Car Forum / Ford / Ford Cars / September 2005serpentine belt adjustment, '90 T-Bird
anybody out there know how to adjust the serpentine belt on a '90 T-Bird? I'm replacing the alternator, and even with the top tensioner removed the belt is so freaking tight, I can't get the bolts into the alternator. There has to be an adjustment, yet I can't seem to figure out where, unless it is the torx bolt on the bottom tensioner, i.e., where one would have to be a contortionist with a whole lot more of hours in the gym than I've got. > anybody out there know how to adjust the serpentine belt on a '90 > T-Bird?

You mean like the 3.8? Truly a PITA but >>>> carefully <<<< use the square hole in lower tensioner to swing it. Top one is meant to be idler only.

Sounds like a 3.8. The tensioner is down low on the motor and is spring loaded. It takes a long 15 or 18mm wrench to swing it up to remove the belt. >> anybody out there know how to adjust the serpentine belt on a '90 >> T-Bird?

Don't try to bolt the alternator on under tension. Remove the belt, bolt the alternator on, loosen/rotate the tensioner(s) enough to slip the belt on the alternator, then tighten/release. Good luck.

Pull the tensioner over with a 1/2" breaker bar at the square 1/2" hole in the tensioner bracket. Take the belt OFF the alternator pulley, THEN change the alternator complete, THEN replace the belt using the breaker bar & tensioner. Thanks for all the replies. I went back to work on it after posting my note - and with brute force from a couple of long screwdrivers, I was able to get it on, but its good to know there's a tool for the belt, as I suspect this car's going to need one sometime in the next few months. >> anybody out there know how to adjust the serpentine belt on a '90 >> T-Bird?
