How do you change the intake manifold gasket in a 3100 Chevy lumina?

that's what it is, i have a lumina, had same problem, replaced the intake manifold. run like a top since

Sounds like a blown headgasket or intake manifold gasket. Sounds like a blow intake gasket to me...It happened to My 86 Mustang and my 96 Lumina.

start with water pump. If its a V6 3.1L have the intake manifold gasket checked. You may have a coolant leak.

I'll assume Lower Intake Gasket, since they tend to cause vacuum leaks. Get a manual from Autozone and expect about 4 hrs labor, you need to take off the upper intake manifold just to replace the Lower Intake Gasket. Probably should change/clean the PCV valve while ur in there. Good luck, man.

had a 95 3.1L V6 Lumina that would lose AF as well. Maybe your intake manifold gasket or head gasket are going bad. If there is unusual stuff on the oil fil cap or dipstick you have a gasket leak.

if you are going to replace the intake gasket you might as well change the head gaskets at the same time[it will cost you a little now but save you a lot later

if you had it heat high enough it very likely worped your heads and or damaged the head gasket

Upper intake manifold plenum leak/crack most likely. If its blowing out coolant then you probably have a bad head gasket.

You may have the problem of your intake manifold gaskets. They are a problems on the lumina. I had to have mine replaced due to the same thing. Also check if your coolant is mixing with your oil if it is. Than it is definitally your intake manifold gasket.

Try cleaning the intake manifold.

A good place to look for Coolant Leaks is around the Intake Manifold, as if the engine has recently started to run rough, this could be a definite sign of a bad intake manifold gasket. Unfortunately, the cost of this type of repair at the local Clip Joint can end up costing you $800.

do i need to change the manifold when replacing thermostat

$150-200 u need upper and lower intake gaskets new o-rings for injectors radiator fluid and you should change the oil

Engine? 3.1L V6 are notorious for intake manifold gasket leaks. get it fixed soon or your engine is at risk. My Lumina had oil in coolant and coolant in oil. If there is tan foamy stuff on oil fill cap, coolant is in oil too.

Remove the cylinder head from your 1992 Chevy Lumina engine. Remove the head gasket and clean the surface. Put the new head gasket on and reverse the process.

You will need to remove the cylinder head from your Chevy Lumina engine. Remove the head gasket and clean the surface. Put the new head gasket on and return the cylinder had to its original position.

you probably have air in cooling system, which is probably caused by blown head gasket(s). Head gasket and intake gasket on these engines are notorious for failing.

loose or broken connections at coils or alternator,not enough fuel reching injectors, or vacuum leak at the gasket between the intake manifold/plenum and throttle body.

The EGR valve on a 2000 Chevrolet Lumina is located inside the intake manifold. A replacement valve can be purchased at any auto parts store.

upper or lower? if it's lower you can bet on paying upwards of 400$

Its too much work. You will need to remove: the throttle cable and sensor tree bracket nearby coils behind the rear head and the coil bracket (7/32 long socket) egr valve alternator upper intake manifold fuel rail power steering pump (requires fuel rail removal first, unless you can get the pulley off) intake rods (don't mix 'em up) intake manifold gasket intake manifold You should now be able to see the cylinder heads!

Torque specs for the Chev. 3.1 intake manifolds are as follows: Lower Intake Manifold Center bolts Step 1 - 62 in-lbs Step 2 - 115 in-lbs Corner bolts Step 1 - 115 in-lbs Step 2 - 18 Ft-lbs Upper Intake Manifold Bolts & Studs - 18 Ft-lbs Specs are taken from Hayes Repair Manual: Chevrolet: Lumina, Monte Carlo, & Impala (FWD) 1995 thru 2005

It's your intake manifold gasket. My 99 Blazer was doing that same thing. Took 5 trips to the mechanic to figure it out and about $750 to fix.
