View Full Version : Serpentine belt replacement? - 1990 Brougham 5.7

Another (probably obvious) question, I need to replace the serpentine belt in my '90 Brougham with the L05, and I need to know how. I've only replaced traditional belts on older cars, so this is new to me. I really don't even know how you adjust the belt tension on this paticular engine. Do I need any special tools, etc? Thanks in advance for the help, I'm awaiting a FSM for this car so I can stop asking noob questions about it, lol.

Thank you,

Stick a 1/2 ratchet or breaker bar in the tensioner and push it to whatever side lets off the slack and take the old belt off. Put the new belt on and follow the routing that is on a sticker under the hood or sometimes is also on the wrapper of the new belt. See if you can find a youtube video, any serpentine belt uses the same general way of replacing it.
Some people also replace the tensioner when they replace the belt, others don't. It's up to you if you want to or not.
