View Full Version : Resurrecting '90 SC

12-13-2006, 02:18 PM
Greetings to all from this new member.

I'm in the early stages of restoring my '90 SC -- owned since new, only 47k miles, but suffering from 17 years exposure to the Texas sun and parked the last couple of years because of a leaky heater core.

Anyway, I've got it all running, licensed, and inspected, and am about to dive into the smaller issues.

One thing I haven't found is a new tensioner/idler pulley for the supercharger. I've replaced the other two, but nobody I checked with seemed to have this one. Can somebody recommend a source?

supercoupeperformance sells stiffer springs for the tensioners but not sure about the unit as a whole.

Kragen carries replacement pullies for our cars. They're metal instead of plastic. You could search for the part number here on the message board.

Go to Advance Autoparts. It's a Dayco part #89007. Just replaced my SC pulley with one of these. It's steel and the pulley only.

The consensus seems to be that the Dayco 89016 is the best match.

I'll get one and see what happens.

Kragen doesn't carry Dayco anymore, they've got .... mmmmm..... I want to say Goodyear, but I don't remember now. Regardless, the new company is MUCH more expensive than the Dayco ones used to be.
