I need help on which timing belt to purchase for replacement. 1998 S70, want to get belt replaced but I have two options, eng #1266128 or #1266127. I thought the correct number would be on the timing cover but it's not, any suggestions? Thanks.

 

Sorry to say but we will need a little more info to be able to tell you which one you will need.

We need to know if you have a manual tensioner or a hydrolic tensioner.

The 1998 was a split year for the 2 different belts.

 

Jayturk, Actually, you should look for an engine number UP TO 1266127, or OVER this number to determine which belt kit you need. You probably don't have either of the two numbers. If you don't have the sticker on the timing cover, the other way to determine which to use, short of removing the cover and checking the tensioners (best way), is the type of ignition system you have. Tech can give you hints on what to look for better than I can.

 

Thanks for the help fellas, I had to take the timing cover off will at a Volvo shop and had it identified. It was a hydraulic tensioner. The guy suggested I change the pulleys if once the belt is off they have a problem turning. The mileage is at 213k, last t-belt change was at 140k, he also suggested to not change water pump since it was not leaking. Does any of this sound legit??

 

I would do the pulleys no matter what.

If the pump is not leaking I would leave it. But thats just me I can do the job in no time as well.
