1997 Sebring Convertible Timing Belt and Water Pump Replacement

Posted by Russell Wright on January 24, 2012

2012-01-24

I found myself needing to revisit a potential leak from the water pump and found the instructions I had written several years ago when I replaced my timing belt and water pump in my Sebring.  These instructions were originally posted on the Sebring Club web site at the following address.

http://www.sebringclub.net/diagrams/96-00-timingbelt-waterpump-replacement.pdf

I’ll be updating them as I do some more work with, hopefully, some better photos.

Original post:

I was motivated to do this work because of a bearing growling sound emanating from the engine. It would grind at low rpms when the engine was cold and then only be noticeable when you initially put on the gas (very quick growling sound). I figured it was the water pump bearing, the tensioner pulley bearing or the idler pulley bearing. At 104,000 miles, I figured it wouldn’t hurt to replace some stuff, anyway.

There were two main reasons that I did this work myself. One, I am a do-it-yourselfer that doesn’t shy away from most any task. Two, I’m cheap! Another motivation was I got several quotes for replacing the timing belt and water pump. The lowest I got was about $600 (and I think it would have been higher). The highest was from the dealer…$1100! All I heard from everyone was how hard this was, so I was thinking I would have to put out some bucks to get ‘er done, but luckily, I reconsidered.

To start this job, jack up the car and support it with a jack stand. I always use the jack and a jack stand for safety. Remove the right wheel so you can get to everything.

image

You probably notice the smaller jack that is under the engine. This is used for supporting the engine when you remove the right engine mount. Removing the right engine mount is one of the first things you have to do.

image

I didn’t get a picture of this, but you need to remove the lower plastic splash shield that covers the a/c compressor, power steering pump, etc. It is held in place with 2 plastic rivets and 3 plastic barbed push fasteners. I was able to reuse all the fasteners when I went to reinstall it.

Take off the power steering pump belt and the a/c-alternator belt. To remove the p/s belt, loosen the bolts and it should come off easily. Notice that the p/s pump has a ½” square socket on it. You can put a ½” ratchet or breaker bar in the socket to hold tension when you reinstall the belt. The a/c belt is removed by loosening the idler pulley bolt slightly and then loosening the tensioning bolt. It’s very easy to reinstall.

image

 

image

Remove the radiator overflow tank by taking out the two bolts and disconnecting the hose. Unbolt the a/c drier (one 10mm bolt) so you can move it out of the way. I also removed the two bolts that hold the power steering reservoir so it could be moved out of the way of the right timing belt cover. There are 3 bolts that need to be removed to separate the engine mount. You’ll be able to tell you have the engine supported correctly as the bolts will come out easily.

image

Here’s a photo showing the p/s reservoir swung out of the way.

image

Next, remove the two bolts that hold the engine mount to the frame. This is done from underneath the car. Now you should be able to remove the engine mount from the top.

image

Remove the 4 bolts that attach the engine mounting block to the engine. The engine mounting block should be easily removed.

image

More engine mounting block bolts, shown from below.

image

Now its time to remove the flywheel pulley. There is a 22mm bolt that holds it on…real tightly! I had to use a chain wrench to hold the pulley while using a ½” breaker bar. I’m sure there is a tool for holding the flywheel pulley, but I didn’t have it. I tried using one of those rubber strap wrenches, but it just wouldn’t hold tightly enough.

Here’s a photo of the flywheel pulley. I actually put the pulley back on temporarily to take this photo. It slips easily on and off the end of the crankshaft. Just be sure to align the pin.

image

Here’s the wrench arrangement I used. I had to be very careful not to mar the pulley with the chain wrench. Man, was it on tight!

image

Now on to removing the timing belt covers. There are three of them. You need to remove the upper left first (near the front of the vehicle), then the lower and then the upper right (near the firewall).

Here’s the lower cover.

image

Here’s the left cover. Don’t have a good picture of the right cover, but it’s underneath the power steering fluid reservoir.

image

After you get the timing covers removed, take the time to line up all the timing marks. The crankshaft has a mark that lines up with a mark on the engine block. The cam pulleys have timing marks on them that line up with “V” notches.

Here’s the crankshaft and its timing marks.

image

Here’s a picture (not very good) of the timing marks on the left cam. Mine had a little bit of white paint on the mark on the cam pulley. The valve cover has a notch in it that should line up with the mark on the cam pulley. There’s also one on the right cam, but I failed to get a good picture of it. Picture, if you can, a similar set of marks under the power steering reservoir.

image

The hardest part (and I do mean the hardest) had little to do with the timing belt. It had to do with the power steering pump bracket. In order to remove the right timing belt cover (nearest the firewall) you need to unbolt the power steering pump from its bracket (3 bolts) and take 3 of the 4 bolts out of the power steering pump bracket, and swing it out of the way to provide clearance for removing the cover. Sounds easy, right? This was the most difficult task for me since the top two bolts are in a very tight clearance area. Here are a couple of photos that show what you are up against. It was hard just to get some photos that show much.

Important!!! There are two bolts on the top of the p/s pump bracket. You only need to completely remove 1 (towards the passenger side) and loosen the other. This will allow enough movement of the bracket to swing it out of the way of the right timing belt cover. Unfortunately, you can’t even see the tops of the bolts from this picture. I’d have to have a fiber optic camera to show you the heads of the bolts. Use your imagination!

By the way, I’m about 6’-1” 220 lbs and was able to put my hands up in that area to get to the bolts, so someone with smaller hands will likely have an easier time.

image

Here’s another one showing where the lower two bolts are on the p/s pump bracket and the 3 bolts that hold the p/s pump to the bracket.

image

And here’s one showing my hand and the wrench working on one of the hard-to-reach bolts. It’s one of those situations where you have to work the bolt a little at a time and, if your hand will fit, finish it the rest of the way with your fingertips. Sorry for the focusing problem.

image

I have a garage full of tools (well, actually TWO garages full of tools), so I thought I would have most of the tools needed to do the job. Turned out I still needed to make one tool, but hey, now I have it. Here it is:

image

It’s made out of a piece of 1/8” x 2” steel bar (could have been 1/8” x 1-1/2”) and two #6 hex standoffs. I measured the distance between the holes on the tensioner pulley and punched and drilled the holes for the screws to hold the standoffs. After determining that the original length of the bar caused some interference problems, I cut out a square 3/8” hole so I could put a socket wrench on it. I could have cut it off to be 1” long, but I was lazy and didn’t want to get the hacksaw out again!

This tool is used to preload the tensioner pulley with 3.3 ft-lbs of torque prior to releasing the hydraulic tensioner. Took me a little while to figure out what they were trying to accomplish in the shop manual, but after careful studying, I finally got it. There are two holes in the tensioner pulley that accept the #6 male ends of the studs. Basically, you loosen the tensioner pulley bolt and put 3.3 ft-lbs of CCW (counter-clockwise) torque against the timing belt and then tighten the pulley bolt. This is all done with the hydraulic tensioner in a compressed mode. To compress the tensioner, remove it by taking out the two bolts. The, using your handy vise on your workbench (everyone has one, right?) compress the tensioner. I suppose you might be able to use a C-clamp to compress it, but I’ve never tried this. The hydraulic tensioner is held compressed with a pin (small allen wrench or cotter pin). The pin is removed after you have preloaded the pulley with the 3.3 ft-lbs of torque and tightened the bolt. You know if you have correctly torque the tensioner pulley as you should be able to remove your “pin” without any excessive force, i.e., the forces are balanced between the tensioner and the pulley.

image

To remove the old belt you can loosen the bolt on the tensioner pulley and then remove the bolts on the hydraulic tensioner.

image

Installing the belt involves lining up all the timing marks and installing the belt over the pulleys in the order specified in the instructions. The instructions that came with the timing belt kit didn’t match up with the instructions in the shop manual. It appears either set of instructions should work.

I used some plastic clips that I got at Harbor Freight to hold the belt on the pulleys while threading over the pulleys in the correct order, as specified by the instructions.

I’ve included a scan of the instructions that came with the timing belt kit I purchased at NAPA.

Setting Up RDP (Remote Desktop Connection) Through Verizon Fios

Posted by Russell Wright on January 15, 2012

I see lots of discussion about getting RDP (Remote Desktop Protocol) to work on a Verizon network.  Much of this discussion is pretty harebrained and doesn’t speak logically about the issues.  Here’s my process and discussion on the subject.

Why do you want to do this?  Because there’s are not many reasons to pay GoToPC or other companies for the privilege of accessing your computer remotely.  Most Windows computers have RDP built in, unless you get one of the “Home” versions of Windows 7, in which case you’ll have to work around that.

The main idea is you want to take RDP traffic coming from the internet (TCP default port 3389) and route it to a machine in your house on your local network.  This will be TCP traffic on port 3389 if you use the defaults.  It’s not much more complicated than that.

I have the Actiontec mi424wr router and my brother-in-law has the Westell 9100em.  I’ve got it working on the Actiontec and next up is the Westell.

This is what you need to do:

  1. Enable RDP on the machine for remote access
  2. Insure you have an account with a password that is an administrator or in the Remote Desktop Users group
  3. Add a port forwarding rule on the router (the hard part) to forward the RDP traffic to a specific machine
  4. Provide rules for any firewall(s) you have running to allow the RDP traffic to your computer
  5. Make sure your ISP or the router is not blocking the RDP port (TCP 3389) universally
  6. Change the RDP listening port to another port if 3389 is being blocked and adjust your port forwarding rule

Enable RDP on the machine for remote access

Type sysdm.cpl in the Start prompt to start the System control panel applet.  Select the Remote tab and allow connections using whichever method you want to allow.  The less secure method refers to the original RDP client on Windows XP and other prior operating systems (might also be the Mac RDP client).  The more secure client can be updated on XP and is part of Windows 7.  Don’t ask me about Vista…just like Windows ME it never existed in my book.

You can add users for remote desktop action if they are not already in the administrators group.

image

Insure you have an account with a password that is an administrator or in the Remote Desktop Users group

To enable remote desktop, you must have an account that has a password, otherwise you’ll never connect.  Unless, of course, you start the Group Policy Editor (gpedit.msc) and make some adjustments to the Security Options (Accounts: Limit local account use of blank passwords to console logon only).  You can also adjust the User Rights Assignment and Allow log on through Remote Desktop Services to other security groups.  But I digress…

image

 

image

Add a port forwarding rule on the router (the hard part) to forward the RDP traffic to a specific machine

On the Actiontec MI424WR router, log  in as admin and click on the Firewall Settings icon along the top.  Select Port Forwarding and select the machine to which you want to forward the RDP traffic. 

image

Next, select custom ports, as there is not a rule for RDP traffic.

image

Here’s how you have to define your port.  Protocol is TCP, Source Ports is Any and Destination Ports is 3389 (or whatever custom port you want to use).  I have performed some tests to change the source port from Any to 3389 (which would seem to make sense for me) and it no longer works. 

image

If you use a custom port the only difference is what you enter in the Destination Ports field.  There are some limits of allowable port numbers, so be aware and don’t enter something like 99999!

image

Provide rules for any firewall(s) you have running to allow the RDP traffic to your computer

You need to make sure the Windows firewall (or whatever extra firewall crap you have running) does not block the RDP traffic on your port to your computer.  Here’s the Windows Firewall version.

Start Windows Firewall (firewall.cpl).  You can simply start typing “Firewall” in the Start box and it will be displayed.  Or you can get at it through control panel.  Whatever…

image

After some testing (turning each profile on/off), I found that the Private Profile on the firewall is what does the blocking.  It makes sense, because the traffic coming from the internet is actually forwarded to the local network, hence it is traffic on the private network.  You open the Properties dialog on Windows Firewall with Advanced Security to easily turn the firewall scopes on and off to check them out.  You might want to turn them off until you get it working.

image

image

To allow the RDP inbound traffic on the standard port of 3389, you can enable the Inbound Rule called “Remote Desktop (TCP-In)” in the inbound rule set.  Simply right-click and enable it.image

If you need to create a custom rule for a custom port (in other words, you don’t want to use 3389 or it is blocked) you must create a new inbound rule.  To create a new inbound rule, select Inbound Rules and the right-click to start the Rule Wizard.

image

Select Port rule.

image

Select TCP for the protocol.

image

Select Allow the connection.

image

Select Private.

image

Give it a name.  This is for a custom rule I was using on port 5207.  

image

Your finished rule should look something like this. 

image

Make sure your ISP or the router is not blocking the RDP port (TCP 3389) universally

Now you need to make sure the port makes it through your router.  To do this, use the CanYouSeeMe.org web tool.  If you have set up your port forwarding rule an your firewall rule, the traffic should go to the port (3389 if the default port is used) you’ve set up.

image

Before I created and enabled the port forwarding rule.

image

Here you can see I’ve created the port forwarding rule.

image

image

Specifying the source port in the port forwarding rule as 3389 instead of An which, I think, should work, but doesn’t):

image

Response from Canyouseeme.org:

image

Specifying the source port as Any:

image

Response from Canyouseeme.org:

image

Change the RDP listening port to another port if 3389 is being blocked and adjust your port forwarding rule

If you want to change the listening port from the default of 3389, you can do this in the registry.  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\PortNumber is the key name.  Change it to the Decimal value of your choice (within limits, of course).

image

No need to reboot.  Simply start the services.msc applet and restart Remote Desktop Services so it picks up the new port.

image

It will also restart the Remote Desktop Service UserMode Port Redirector (which really makes sense).

Notes From a Failed Installation of a Parrot CK3000 Evolution Bluetooth in a 2002 Prius

Posted by Russell Wright on January 2, 2012

1/1/2012

These are my quick notes so I don’t forget what I spent a great deal of time doing on 12/31 and 1/1, without a positive outcome.

Purchased a used CK3000 on eBay and took my chances on whether or not it would really work.  Tried to save a few bucks…probably a bad idea.  The CK3000 in my 1997 Sebring convertible works great.

Removed the dash to get to the radio using the instructions located on Coast Electronic Technologies web site.  Relatively easy process, but quickly found that trying to release the clips on 10+ year old plastic quickly yields a handful of broken plastic clips.  Also had to glue the left vent back in place, as it snapped off its standoff that it is screwed to.  Very fragile after 10 years of Texas heat.

Purchased a Metra BT1761 for $29.99.  I think the QCTOY-1 wiring harness is the same.  Found that the CK3000 (s/w 5.11) was an Eclipse model (not marked as Evolution, but is supposed to be the same).  Also found the CK3000 didn’t ship with the ISO power adapter, so I had to do some soldering of the CK3000 power cable to tap into the power.  Since I didn’t have the correct power cable with its connectors, I had to cut the double female ISO connector in two with a hacksaw so each connector was separate.  That way I could plug it into the duplex male connector and feed the power back to the radio.

The speaker connectors and the muting relay box seemed to work, since the speakers on the car correctly worked when everything was connected.  The problem, however, was when power was applied to the brain, there was no indication of power on the controller (no lights).  Even opened up the controller to make sure the wires were attached.  There was also a pin on the small brain connector (white wire) that was pushed out of the connector.  I had to bend the lock back so it would stay in place.

The operation is straightforward.  The speaker relay box is wired so as to disconnect the back speakers and route the phone audio through the front speakers when the phone is active.

Not sure if there is really a TEL/MUTE function on the radio, although the wire is there on my Prius harness.  Doesn’t really need it because the speaker relay box would take care of muting the radio.  The mute wire (yellow) is there if you have another function that needs to operate the mute functionality.
