Belt squeak after alternator replacement
Belt squeak after alternator replacement
So my factory alternator quit at 240k miles which was great it had a long life. I replaced the alternator and with new belts for both the a/C alt and the power steering. Car drove completely fine for a few weeks now I've got a nasty loud squeak from the power steering pump on startup. It lasts for about 30 to 45 seconds then clears up. The squeal is coming from the power steering pump itself. Buddy says bearings are going in the pump.
So my question here is, could I have over tightened the tension on the belt for the pump? The pump it self is old, it's been humming since I bought the car about a year ago but never leaks anything on the ground. I've noticed the suction/feed line is saturated and has a little residue on it. I believe this to be the original pump. I purchased new o-rings to possibly stop the pump from leaking or taking air in. So back on topic here, when I did the belts it said to have about 1/4" of give when I press on the belt after installing it. I took the car for a ride and checked it again after install and it seemed to still be in place. But have not checked since then.Any help is appreciated.

you sure the belts are not loose?
sometimes brand new belts will stretch a bit after the first few days or weeks,
thats why you should install new belts tighter then a belt you are just re-installing

Re: Belt squeak after alternator replacement
Why do you say the PS pump will need replacing soon? Common issue with the reservoir is the o-ring leaks air into the reservoir and causes foaming of fluid and noises - simple fix.

For others just search on power steering oring or foaming.

So I reinstalled the PS belt on t he pump... I tightened the adjuster until tension was where it should be on the belt, and retightened the lower nut on the pump then the large nut on the other side of the adjuster screw at the top. I started the car, NO SQUEAL! but it did start to make a few random chirps when the throttle was in the idle position. Give it a little gas and never hear it/like it's gone but comes back slightly at idle.
I drove it around in the parking lot to try and replicate the chirp as if I were coming to stop at a stop sign or stop light, it wouldn't do it. Hopefully I've solved this. We shall see on next cold startup.

Re: Belt squeak after alternator replacement
Was the noise like a loud buzz or moaning that changes as you try to turn the steering wheel (pump), or was it a horribly loud screech (belt)?
The inlet hose fitting on the PS pump comes right off with just one bolt, there's a single O ring that seals that fitting to the pump. As it ages the ring hardens and starts leaking--it can let fluid ooze out and it can suck air in. That is how most of them get foaming fluid, but on some the hose gets loose on the reservoir as well.
The reservoir has a filter screen inside it, that screen can get restricted with age and miles and can make the pump howl even without a leaking O ring. Reservoir is pretty cheap to buy new from Honda.

Spoke too soon. Usually it did the loud squeal on startup. Did not do it this time, it squealed while going down the road for a brief moment and then quit, so it's looking as though I didn't solve the issue but rather delayed it? Which is terrible because I know I got that PS belt tighter than it was when I started this ordeal.

As far as the belt screech it's seeming to be related to the PS system, but the question is why? It's been adjusted 2 times now and it's still making the sound.

Re: Belt squeak after alternator replacement
IF you get a belt screech immediately after startup and/or when the AC kicks on, it's the alternator/AC belt. (this is still my vote)
IF the belt screech happens when you crank the steering wheel all the way to one side and push it, then it's the steering pump belt. (don't confuse belt screech with pump moan and buzz)
Each of these situations presents a high amount of loading on the respective belt, and that loading is when the respective belt is most likely to slip and screech if it's not tight enough.
And...if you aren't turning the steering wheel, the PS belt is nearly freewheeling/minimal load. It's not gonna make belt noise.
IF PS fluid has puked out and got on the belt(s) then all bets are off. Clean up the mess, fix the problem, clean pulleys, replace belt set.
