Re: Serpentine Belt tensioner
Looks like I have the solution.
Many thanks to Callaway cars and Boostedmaxpsi
Turns out the 1987 used a different method to lubricate the turbos.... apparently a pump mounted to the front of the power steering pump.
This turned out to be not a great solution and in 1988 they changed it to a pump mounted to the serpentine belt tensioner
See cut & paste from relevant section:
1987 cars had a pump that was driven off the front of the power steering pump. This pump is obsolete! If you see one of these on a car call the factory immediately. All cars should have a scavenge pump that is integrated with the accessory belt tensioner.
So the 1987 should be using a 1988-91 serpentine belt tensioner (the 1987 one wont fit).
I have one on order and will report back once its on and working.
Hope this helps all 1987 CTTC owners as well as 1989-91 Owners

Re: Serpentine Belt tensioner
Is 2250MM the correct length belt for 1989 as well?

Re: Serpentine Belt tensioner
Callaway Chris - were you able to measure the belt in your office? Thanks
