Question about 1997 Buick Riviera

3 Answers

I have a noise coming from (what I think was the S/C). I found out that it was the coupler. I replaced the coupler, reassembled and I still have the noise. I then went and replaced the tension pulley(s)and idlers. Still have the same noise. I hear a loud click when I start the car and when I turn the car off. This all goes away when I give it gas. I am at a loss. any idea? Thanks Sickriv. Ps. its a 95 124,000 3800

It is probably the supercharger coupling located inside the supercharger. It is a plastic disk with several holes. Half of the holes match the compressor shaft on the supercharger compressor the other half are on the drive for the supercharger that has the serpentine belt driving the supercharger. The holes wear oblong the make alot of noise at idle. Under acceleration the noise goes away since this torque has caused rotation into the far end of the oblong holes. Not a major problem but it sounds really bad at an idle.

Have you tried checking the traction control module if its a clicking noise and you step on the break it goes away and comes back after a while then you need to check the abs plugs and the bake pads

Hi can some one help me if got audi a 4 1.9 i replace headgasket new cam set now i start ca make noise sound come from cam shaft i dont know why,,:

I suggest you have a professional listen to the noise. It is kind of hard to diagnose engine noise from this keyboard. I would suspect you did something wrong when you reassembled the engine.

Hello all, I've bought a 57 reg V70 that has a rumble coming from the nearside underframe. All suspension bushes, etc. have been check and nothing found wrong. The noise is there all the time, not just on...

first thing to come to mind is a wheel bearing, being a noise that 'rumbles'-jacking it up, one wheel at a time and turning by hand might reveal which wheel is making the noise. Does the noise 'change' with speed, or braking? Noises are tough over the internet, but your description leads me to think they need to be checked first.

I have a rattling sound coming from the coupler. The motor seems to have a loping or missing to it too. Would the coupler going bad cause this?

are you sure it is not the iac valve you are hearing. this could cause a miss also and make a noise. If it is the coupling , it is a fast fix. If the coupling is bad enough it could cause some problems. You know the coupling itself can be found on E-bay for under 40.00. Then 12 oz. of special charger oil and a hour of time to replace. Have you checked the OIL? To replace the coupling , remove the belts , I think about 6 bolts , and pull the nose off to access the coupling. First try and remove the oil. A spray nozzle from any bottle will fit in the fill hole to squirt out the oil to a bottle. After the oil is out , the bolts(allen head I think) are removed ,pry off the cover . the coupling will be right there Put it back in reverse with new oil and torqe the bolts back , belts and you are ready to go. Since the coupling needs replacing anyway do it and then check the running of your car. I am told the dealer does not sell just the coupling so you have to get after market.

I have a 2001 chrysler voyager that is making a noise

I have the same problem. Have a late 2000 Voyager. A company recently replaced the shocks and reassembled the struts. I now found out that they did not assemble them correctly. The noise is from the strut central nut working loose. It is a serious problem in my case. I would get one of your struts removed and checked ASAP.

Noise coming from turbocharger

1995 riviera is not turbocharged; it is supercharged--big diff; if the noise sounds like rocks tumbling, then you need to replace the plastic coupler in the supercharger; part is cheap -;labor is a lil high; it is a pain because you have to remove the alternator bracket on the buick version of the 3.8

1998 Pontiac Grand Prix GTP Supercharger coupler

The rattle you are/were hearing is typical on the Eaton blowers. After they get some miles on them, the coupler wears out and the holes become ob-longed or out of round which causes the rattle you are hearing.
Usually at idle you can hear it very clearly.
I have changed a few, and they are pretty simple to change. Just take off the supercharger belt, then you may have to remove your alternator bracket, depends on which years, drain the supercharger oil with a spray bottle sprayer (it does stink badly) then just remove the 10 or so bolts that hold the snout to the housing. Remember to keep track of where they go, some are different lengths.
You may have to use a rubber mallet, or your hand to hit the snout around to break the gaskets loose. Pull off the old black hockey puck looking thing (coupler) clean out the snout, attach new coupler, then reassemble and put new supercharger oil back in, and your rattle will be gone, at least for another 100k miles.
Best place to get a coupler is at,
Costs about 30, plus the few bottles of oil for the supercharger.

Transfer case? Front diff? HELP!!

Sounds like a transfer case problem. But I can't verify that from here. Coupler is inside the unit on the output shaft and needs teardown to get to it.
