loud belt at idle
#1305679 - 08/24/06 01:08 PM

I just replaced my timing and serp belts. Before the change, the dashboard would shake at idle but after searching I assumed it was normal for a '95 zetek and decided to live with it. I have done all of the tune up items talked about on the board and other than the idle, its great. If only there was a way to adjust the idle - I am sure the problem is just that the rpms are a bit too low but according to searches here on that topic there is no way to increase idle rpms.

Anyway, after replacing the belts now instead of dashboard shaking I get VERY loud belt squealing at idle. I think that since the belt is slipping a little, the load on the engine is therefore less, which results in less shaking.

I just wondered if anyone had a solution to the belt noise. It only happens at idle, while in drive.

Check engine/tranny mounts. Did you replace the tensioner and idler pulley when you changed the serpentine belt?

The mounts are good and the pulleys were replaced. I am thinking of trying a different belt but am not sure what are the odds that will help. The one on there now I bought at autozone - not the gatorback kind, the regular one.

The real problem is the darn low rpm idle. With just a hint of gas pedal (while holding down brake) it purrs perfectly.

Did you mean the tensioner was also replaced? Yes, I would try a different serpentine belt too.

I was thinking of my crown vic tensioner pulley. I can't remember if I replaced it on the contique, but if the tensioner and tensioner pulley are one unit, I am sure I did not replace it. I'll try a new belt.

Johnoh, I adjusted my idle by taking up the slack in the throttle cable and adjusting it out one notch where the housing attaches to the throttle body.

Take the clip loose that holds the cable housing in place, and pull the housing out a little, until you get it where you want it. Put the clip back on, and it should idle a bit higher. Just do it a notch at a time, until it's where you want it. You don't want it to idle too high.

Welcome hopalong that is what I was looking for! Although I am not quite getting your instructions so please bear with me a bit.

There are two cables, the (throttle?) cable which is nearer the TB and then two inches toward the passenger wheel is yet another cable (the speed sensor cable?), which has a green plastic connector about an inch long near its end. So I am not sure which of these two you mean.

Also when you say "take the clip loose that holds the cable housing in place", I'm afraid I do not understand that.

There is the springloaded spring-wound housing (which I am thinking is the cable housing you referred to) that connects directly to the TB, but I do not see how its clipped or how I would loosen it. There is also the cable guide housing where the cable goes from bare wire to plastic-covered wire, but I am thinking you do not mean that.

Would you mind taking another go at the instructions? Thanks a million.

Side point - there DOES appear to be an idle adjustment screw on the passenger side of the TB, but I do not see how one could turn it. By removing the passenger-wheel facing allen-head screw that connects the springwound housing to the TB, you can then see a screw under it that has no visible way of turning it. Its about 1/4 inch in diameter and sits vertically and protrudes down below the housing, and a piece of metal on the housing hits it which causes the cable housing to stop. If I could turn that screw, it appears that the cable housing would not be able to loosen as far, causing the throttle plate to be kept slightly open. Hmm
