Haynes Repair Manual, 1987 thru 2003, All Models:

Exhaust Manifold, removal and installation

2.4L four-cylinder engine - "Using a new exhaust manifold gasket, install the exhaust manifold and hand-tighten the mounting bolts".

2.5L four-cylinder engine - "Remove the mounting nuts and spacers and detach the exhaust manifold from the engine. Clean the mating surfaces. Reinstall the exhaust manifold and finger tighten the nuts on the end studs". NO mention of a gasket.

4.0L and 4.2L six-cylinder engines - Slightly different procedure for removing bolts and nuts for different years but,,,, "Remove the nuts that secure the exhaust manifold to the cylinder head and pull the manifold off the engine. Remove all traces of old gasket material from the mating surfaces. Position a new gasket on the locating dowels and slide the manifold over the studs".

Intake manifold, removal and installation

2.5L four-cylinder engine - "Drain the cooling system".

All other engines, no mention of draining cooling system.

I hope this helps clarify this subject.

I like the idea from the guy that talks about expansion and contraction of different materials. Maybe if you have a stock exhaust manifold, no exhaust manifold gasket is necessary? But maybe if you have an aftermarket exhaust manifold or header, a gasket is necessary? Thos manifolds sure are heavier than they look once you get them off.

Black 94 Wrangler S. Basic and fun!

Like I posted earlier lots of people say the dealer gasket is the way to go.

just replaced my exhaust manifold today in my 89 and no gasket for exhaust but there was one for the intake. I bought a gasket and used it. it covers for the exhaust and the intake and seems just fine. By the way I thought it was a pain in the butt to replace the manifold but my old one looked like swiss cheese and made my jeep sound like an airboat so it was neccesary. just hoping I dont have to do it again anytime soon. good luck

Alright!

We changed out the old gasket, wich was poop, and put the new one in, replaced my missing bolts, and my jeep sounds awesome now. Its so quiet, im not used to it being so quiet. New milestone: My spedo read 70mph (So i was really goin about 75) I didnt even realize it, was goin down a hill and noticed my spedo, and slowd down alittle.

So anyways...

Yes on the gasket
No on the draining the coolant on my 2.5
And it fixed my problems.

Im so happy.
