98 v70 na timing belt replace - question

Post by **corviarbob** » 23 Nov 2015, 15:50

there are a few u tube videos on removing and replacing those covers. i just did a 99 c70 and it was not a bother to remove the covers and replace them. the hardest part was getting the belt into the crank past the plastic covers, the rest was easy. then the serpentine belt of which i did not find any reference to replacing. my owners manual showed it wrong. i finally got it after a few tries. good luck

I removed the intake cam pulley and the lower TB cover went right in. This is my daily driver and I had to make a decision and go with it around 1:00 PM today. I marked the cam pulley relative to the camshaft before I pulled it so I should be able to get it back to approximately how it was. Hopefully I'll get lucky. Repairing the lower TB cover with fiberglass was easy but time consuming. I am somewhat concerned that it won't adhere well. That said once its installed in really doesn't have any stress on it.

A new OEM lower TB cover is only $43 at dealer.
When using used part, it is often old, weak, brittle and can break during installation
Having said that your repair should be fine, hope that none of it breaks sending shrapnels onto the timing belt itself.

The problem with having an old car as the daily driver is that I have no alternative to get to work. The part broke on Saturday at 11 AM. My first stop was the dealer and the soonest they could have a new one in my hands was about 3 PM Tuesday (today). I'm going out of town tomorrow morning. So using a used part was my only possible option. I'm using a vacation day to work on it. If I was retired or worked for myself and my time was flexible or I had a spare car this would not have been a problem. The car is in the driveway so I can't work beyond around 5 PM because its get too dark to see.

I hear you. This is why when I do a complex repair such as TB, I prepare for all contingencies by:
- Having someone on standby in case I can't fix the car on time.
- Get PNs ready, and when in doubt I got the parts sitting there ready to go in if I need it.

In any cars, most of the plastic parts are brittle at 150K anyway.

I had a ride to work lined up just in case and at the last minute she backed out because she decided to take the day off. I'm 56 and she's about 40. Younger people for some reason don't understand the meaning of commitment. She also drives a volvo. Next time she needs a ride we'll see how willing I am to help.

I spent a lot of time preparing and reading the info available here. I had parts on hand - all of them- except the lower timing belt cover. I never anticipated it breaking. A job that took me 3 days elapsed time would have taken me just about 5 hours if I had the part. My repair isnt that great. Epoxy doesn't adhere well to plastic (peel strength is poor). That said I think it will be OK.

I finished up today. Fired her up an she lives on! Timing may be slightly off. I don't know what the car's idle RPM is supposed to be. I'm right at 925-950 which I think is slightly low but it's OK.

Is the lower timing belt cover absolutely essential? Mine broke when I was trying to get it out. (I couldn've sworn I was supposed to get it out...) I can still screw it on, so it's not broken around the screws, but it's not one piece. What happens if I put everything back together like this? I couldn't get it off for the life of me. (And I can't imagine trying to get one on!)

You don't want road debris, mice, and Swedish fish getting into your TB. I would say essential.

This is because the Lower TB cover needs to be installed with the Water Pump.
I mentioned that in the Timing Belt DIY.

Now, if you don't want to remove the WP to install the Lower TB cover, then I guess you can trim a bit around where it meets the WP to allow it to be installed. I maybe wrong though.

I noticed those cutouts in the lower cover! I don't think I would've gotten the water pump on had it not been loosened. But I was kind of rough with the cover as I was trying to remove it. (It was PAIN to clean the old gasket off with that cover there...) I'm gonna have to asses its stability before putting everything back together again. Hoping for a Thanksgiving miracle here!

By the way, have a happy, joyous Thanksgiving everyone!
