Question about 2007 Cadillac CTS 3.6L
I need to change the lower intake manifold gasket of my pontiac grand prix GTP 1999, do I have to change the Supercharger gasket and what difference makes to install a thinner and a thicker gasket on the SC.
Is there any place where I can see the procedure.
Technically you are supposed to (change the s/c gasket) but if your careful and don't tear it, you don't really need to.
Be sure to inspect the yellow coolant o-rings.
The gasket thickness isn't going to matter at all on the supercharger gasket.
Perfect oportunity to install that Intercooler you always wanted ;)

you can not put a regular 3800 intake in place of the 3800 super charged engine,the compression ratio is lower than the regular 3800 engine.......!

sometimes they just go out....lack of lubrication can cause problems but more then likely it is just going out. Try taking the air cleaner off and reaching in where the fins are and you will see a nut on the end, grab the nut and see if there is any play moving it up and down. If there is any play then the bearing is going out.

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.

The oil should be changed every 30K miles according to the Pontiac manual.
However, it is best to change it sooner or whenever you don't know when the last change was done.
