Hi all. I pulled out of the bank yesterday and all of a sudden, Clunk, Rattle, Squel..... NOOoooooo! This sound kept repeating until I turned off the A/C and now at 6 hunderd rpm's it sounds like a pully is going to fall off.
Do you think its the A/C cluch?
I think this vette knows when I have extra $ in the bank?!?

 

So you hear the noises then revved it to 6k why?

 

If it's an L98 fairly stock you shouldn't really be pushing the motor that hard to begin with. After noises? Your asking for trouble.

That noise was probably the clutch. This is what comes to mind.

Your compressor ceased up. The clutch engages against what is essential a solid piece of aluminum (Clunk). The pulley stops and your belt jumps (kinda like when you slam on your brakes on a really sticky road and you get wheel hop....scary!) which jostles your tensioner (rattle). After the initial jump, the belt rubs up against the stopped pulley (squeal). The A/C clutch realizes something isn't right and releases.
Repeat.
Well, it makes sense to me.

Get new A/C compressor (OUCH)

 

Opps, i meant 6 hunderd

 

Could be the clutch, some more like the compressor since it goes away

 

Okay, 600 sounds better. The slamming from the clutch that I mentioned above either bent the shaft or cracked the pulley. When my Bonneville SSEi had a bad pulley, I heard it around the same RPM.

New compressor or get the delete pully......there is another option....

It's my favorite option.....

Put a supercharger there......
Just a few pounds, no biggie

 

I realy like the air, do you know a good place to get another compresser?

 

The damdis thing, after looking at how to remove the compressor it looked like the S belt was very loose. Turns out to be the power streering pump mount is broke off so the compressor sounds off when I turned it on and the power streering pump pulley is resting on a hose clamp and burned 1/2 way through it. Wow!
Anybody got a mount cheap?

 

Take it off and have it welded.

 

HMMmmmmm, I'll check that out. Is that Alum?

 

Check out some of the Vette recyclers or watch the Parts for Sale for a part out.

 

I found a mount for $35 bucks shipped!

 

My smog pump siezed, shaft sheared and the pulley fell off at 85 mph. I shut it off, and coasted off the freeway to a stop.
A friend went to a wrecking yard for me, bought a pump, drove it over to me, and I installed it on the side of the road. He also brought me some wrenches and a screwdriver.
A cop came by, and told me I couldn't park there. So I asked him for a 1/2 inch ratchet or a breaker bar to get the belt back on the idler, and he had some home made funky 90 degree tool that just happened to be just under a half inch at the business end, but it was 3 feet long.
Just enough to get the belt on, and I moved the car and tightened everything up about 50 feet away in a private driveway. I think the person that lived there must have already gone to work because nobody came out to find out what I was doing.
Happened last month.

 

LOL.

I have had road side adventures like You too.

Last week I ran out of gas in my 87 Vert.
I forgot to fill up the tank the night before.
After work & had to run to the south side of Peoria, IL to pick up some Bobcat skidsteer parts for the RH final drive unit for a buddies Bobcat machine.
I made it there before they closed.
Drove 50 miles from work in 40 minutes.
I am not from Peoria, IL so I trusted my Garmin.
It took me straight through the Ghetto.
No big deal.
Made it to the bobcat dealer OK.
Driving back I cut through the bad side of Peoria in my bright 87 Vert.
I ran out of gas right in front of the projects downtown.
I said to myself OH........chit. LOL
My bright red 87 vert caught attention within 2 minutes.
Every hip hopster on his cellphone wandered by in their Caddies & on foot.
I managed to start my vette on fumes & swung it around 180 to a side street 2 blocks away before the engine died again.
Called the wifee..........she was mad.
LOL
Ran out of gas where?
A cop rode by 20 minutes later.
I waved hi.
He said to me what the Fick are you doing here????????
I ran out of gas...........
Am I going to get shot after you leave?
Na no...........roll your windows up though he told me.
Long 40 minute wait for the wife to come by with 2 gallons of gasoline.
Dumped the gas in into my Vette,
wife was still pissed.
I burned rubber home.
