Thread: GP Upper and Lower Intake Manifold Coolant Leaks

Many have.

It's a stock replacement, just buy the revised manifold from whoever.

Or are you talking about swapping on the aluminum L26 intake manifold? Because you can do that too.

Also; aluminum elbows are just as simple as replacing the stock plastic units.

If you're in there, might as well replace the lower intake gaskets too...and put in the metal ones instead of the plastic ones there to boot.
