Thread: Belt Replacement

  1. #1

    Default Belt Replacement

    Hey guys still in the process of fixing this old girl up, it needs the belts replaced at least I hope that's all it needs cause it made a lot of chirping and almost screeching noise last few weeks, and I tried using some belt dressing but I think I only made it worse cause now the belts are gunked up and sticky so...time to swap them. Here's my question what's the easiest procedure to do this because my 87 has two belts I'm not sure when they did that but I thought my old 86 only had one big main one. The way this is set up though it looks like I'd have to remove the fan to feed the belts over the pulleys cause the fan and fan shroud are in the way. Please help me understand this lol.

    If it helps; my motor set up is the alternator, power steering, and water pump are on drivers side, the passenger side has the ac, air pump and whatever other pulleys to control...

    Thatís a normal setup. You have to install the ac belt first and no you donít have to remove the fan just go around it. Itís just like any other car really.

    belt fishes around the fan. It doesn't come off.

    upper and lower bolt loosen on the alternator for that one. For the AC side there is a bolt facing forward just under the AC compressor and one in the rear you have to fish under the compressor to loosen so it will move. Square hole in the tensioner fits a 1/2" ratchet to tension the belt.

    Spin the pullies, make sure nothing is scratchy. The tensioner tends to get rough and make a lot of noise, same with the alternator.

    So the passenger side belt than driver side? Sorry I feel like an idiot but normally with cars I never had to work around the fan or anything all the pulleys were right in plain sight, but than again I'm use to working on motors from the 2000s and up so this is different.

    Also as far as the tensioner is the square hole facing toward the firewall then? Cause from what I saw there is no hole or bolt sticking out of any pulley from looking at it from the front view. I can send a pic tomorrow but I know about loosening the alternator so that belt should be easy now that I know it just fishes around the fan..

    Yes, the ac belt is on the rear so itís the last one to remove the first to install.

    The hole on the tensioner is on the front near the pulley itself. You might have to feel around for it.

    Dont be afraid to start the car up without any belts and listen for any strange noises. May aid in finding out your issue.


    Like was mentioned alternator belt replacement requires loosening the upper alt bolt and the lower alt bolt.

    The Ac belt requires you to loosen up the bolt behind the tensioner (think under ac compressor from behind..PITA). I would also crack loose the 4 o'clock position ac compressor bolt.

    Below you can see the 4 o'clock bolt and the square drive just to the right of it and almost hidden by the belt



    Here you can see the pivot for the back bolt of the tensioner:



    You just work the belts out by spinning the fan and fishing it out...same for reinstall.

    Goodluck.

    Yes thank you! This is what I needed to know, that tensioner pulley I thought had the square hole or bolt sticking right out of the front of the actually pulley part not on the side of the housing that's why I was confused. I started the car without the belts on and it's quiet as a mouse but if the pulleys aren't spinning aside from bad belts it can also still be one of the pulleys so I'll check them tomorrow when it's light out and hopefully find out it's just the belts. Removing them was easy I just cut the damn things off since they were junk anyways lol.

    So guys it's pretty cold here today so waiting till it warms up a tad before I throw my belts on, I noticed all the pulleys are fine, but the power steering pulley had a bit of play is that normal or could it be causing the noise? I'll obviously know either way once I put the belts on but just a little knowledge before hand would be cool.

    Normal for that to have some in/out movement.

    Thank you gadget relieved to find that out.

    So I put the alternator belt on at least and everything is still quiet so that's good, how necessary is it though for the ac belt to be put on? I know it works the air pump but my brakes seem fine and the climate still works. Is it even necessary at this point? Besides the motor running rich the car wouldn't be driven much at all though. If it will hurt it I guess is my question.

    You can run it with that belt off and it wonít hurt anything. It wonít run rich either, the system doesnít work like that.

    Thanks man yeah I just found that out, it seems to only effect the cats but nothing really with the motor so that's cool. She's good to go again now time to get different tires for her lol.

    air pump has nothing to do with the brakes. Its emissions stuff. AC also won't work, which to me is a much bigger tragedy. I lost the air pumps years ago but the AC is a hard requirement.

    if you run the car in winter having working AC clears the windshield faster. Also the AC gets run in the winter which is better ten letting it sit.

    Oh trust me I hear ya but I live in wisconsin AC isn't something I ever really needed but right now if I can get away without it to me it's a bonus cause the car was about to be parked because of this. I never ran ac in my cars in the winter I only learned about that a few years ago, but the ac in this car didn't work anyways compressor is shot and I always drove cars all my life in winter without ac on. I'll still get it back on but now I can wait till spring and happily still drive her and I didn't even know about the belt bypass to just have only ac and not the air pump. This is new to me still for this era car lol.

    Hey guys figured I'd just put this in here instead of posting a topic that's been hammered to death. I'm looking to replace the wheels cause I have a family member getting rid of a set of tires and rims from a ford. The tires are all 235/75/15 will these fit on the car? I know they will fit on the rear no problem since 245 and up to 275 have been ran in the back with other people's cars but the front is where I'm not sure. The car will only be driven in town for the most part for now. If the rims don't fit I don't even mind cause I wanted to get a set of turbines again those would be a bonus.

    I know a 235/70R15 fits. The 75 gives you another inch. If it were gonna rub, it'd probably be the back side on the plastic inner fender liner nearest your feet.

    Thanks Tiggie I tried installing the rims that came with these tires and no luck, the rims are simply too big 5 x 5.5 or whatever they came off an old truck. So I'm picking up some turbines I found at a salvage yard the only question I have is these are coming off a 90 Mercury GM, and the only concern I have is these are 1" diameter is it possible I need the 1 1/2 ones or whatever? Just want to make sure before I buy these cause I have to drive a few hours to go get em.

    What diameter is 1"


    If the turbine wheels are coming off of a 1990 Mercury Grand Marquis you will have no issues installing them on your 87.
