Some customers may comment on coolant leaking from the engine.
The gasket located between the coolant crossover pipe and the front of the right (rear side) cylinder head may be leaking.
Replace the coolant crossover pipe gaskets with current service replacement gaskets, P/N's 12577704 and 12590668. Before installing the new gaskets, make sure that the mating surfaces on the crossover manifold and cylinder head are completely clean and that NO OIL or OIL RESIDUE exists.
