Engine coolant leaks that have been detected on some 3.5L engines may be the result of leaking gaskets between the coolant crossover pipe and the front of the rear cylinder head.
There are a few different designs for the crossover pipe, but the leak is generally from the same area, the gasket in question is just below and to the rear of the power steering pump. Replacement of the crossover gaskets is necessary to fix this concern.
If you would like any additional information or have more questions please don’t hesitate to ask!

Is there one gasket for both sides of the coolant crossover passage or one gasket for each side? Also do I need to remove any other parts first to get to this gasket?
Ok, there is one gasket for each side of the crossover assembly. To replace the crossover gaskets, you must remove the Power Steering Pump and Alternator and any other Items that are mounted to the Crossover Asembly so that you can remove the crossover to access the gaskets. I was looking for some good illustrations but was unable to locate any close ups as needed...
