Supercharger coupler replacement

**Leedeth** · 04-11-2014

So I went to the dealership today, picked up some supercharger oil, and asked for some anaerobic gasket maker. He asked if it was for the intake or something, I told him it was going between the supercharger snout and the supercharger housing. He came back with some AC Delco "Engine Sealant" part number 88861418 which didn't say if it was RTV or anaerobic sealant on the box, so I thought it was the right stuff.

But now that I can look it up, it says it's RTV. http://acdelcochemicalcatalogue.com/...hp?prod_id=129

Is this right or did the guy not give me the right sealant?

Also, when sealing up the supercharger does both sides of the housing need to have sealant or just the snout?

Thanks in advance. It's a 1997 Grand Prix GTP.

I used red RTV on mine and ive never had any issues. Just spread it on the snout and snug her up.

Both sides of the rotor pack housing need the sealant.

i have the giant 1.69 fl oz tube of GM gasket maker (loctite anerobic sealer rebadged for GM) GM# 1052943

rtv is not ideal as more than a fingerprint thick can shoot a good amount of rtv towards the gears as its tightened down...people use way to much rtv it seems lol

ive pulled apart a blower with rtv shredded all through the gearbox.

i prefer to use the anerobic sealer (without hardener, easier for future repairs and it seals just fine without it...easier to cleanup) as we are talking about a component where you dont want excessive runout to prematurely wear out bearings and seals/parts/rotors/case

I used the AC delco stuff and it appears mine isn't leaking.

We have tons of little 30ml tubes laying around at work, did the job just fine!
Where are you located? Maybe you're close to me...

Ah, thought you might be closer! That's about as far as you can get!

Also people seem to not know that when using RTV as a gasket between two smooth surfaces and not as a filler, you are supposed to let it get tacky before you assemble and torque down.

Same tube here and ... always less is more in this case.
