Thread: lower intake gasket job list

gonna replace the lower intake gaskets on my 2001 grand prix 3.8 NA

gonna flush coolant at this time and get rid of the dexcool

planning on replacing the coolant elbows also at the time

was looking at this kit at autozone, is this everything I need?

thanks

yes sir that is everything you need besides the coolant, coolant elbows,oil, and oil filter, and rtv for the four corners when installing the Lower intake manifold. After you're done changing the lower intake gaskets and the job is complete make sure you drain your oil and refill with fresh. I go a little over the top and do my refill with a cheap oil, run the car for 5-10 minutes, then drain and refill with mobil 1. All up to you on how safe you want to be making sure all the coolant/water is out of your oil.

got it, changed to the felpro

added thermostat to the list

thanks

making my girlfriend buy me this for doing the work for free

also the felpro doesn't include the upper, so do I need this too?

Felpro/Intake Plenum Gasket (MS95812) | 2001 Pontiac Grand Prix 6 Cylinders K 3.8L SFI OHV | AutoZone.com

the intake isn't leaking just doing it as preventive measures

So is the Felpro that much higher quality?

im in stillwater

what else?
so far
felpro LIM
felpro upper
dorman intake elbows
thermostat
coolant
oil/filter

earlier this spring I put in all new plug and wires, rear brakes, outer tie rod ends, belt, air filter

just finishing what I meant to do earlier

10-4 Billboost,

thanks for the heads up!

thanks for everyone's help, job done and running good!!

Couple tips I learned -

buddy mechanic told me to put a good bead of black RTV sealant on the vally, then lay down the vally rubber gasket and lay another bead.
Remember to transfer the little black hose on the upper plenum intake gasket

other than that it was super easy compared to my ford powerstroke 6.0 oil cooler rebuild job haha

Oh and one more thing, autozone had to special order both felpro gasket sets and did not have the dorman coolant elbows in stock.

Oriely's had everything in stock!

Check that upper manifold in the EGR are to ensure it's not getting weak. If it seems weak, etiher plug the ports or replace upper.

I went looking for that thread Bill, cause I will be doing the same thing, and I can't seem to find it...I know it used to be stickied...(shame it still isn't, was a GREAT write-up!)
