I have a 1997 and 2001 XJ. I notice that when I order parts, some of the gaskets are different material even though the mating parts are the same. The water pump, thermostat housing, and front cover seals are the ones I'm talking about. The old style was more of blue paper and the newer one are gray. The water pump and thermostat housing gaskets also have a red bead on the newer style.
I am wondering if the newer style is better? Why do companies still sell both?
