I had posted yesterday about changing the Y-pipe with cats on my 3.0 Ranger, which I will do soon. Ive heard that the 3.0 Vulcans are notorious for coolant leaks from the timing cover. While mine doesnt leak, would it be senseless to change the gasket and water pump as preventive maintenance? In October I had to drive through some saltwater (storm surge) for about 20 miles to get back home. I dont know if thats what caused it, but theres a small amount of corrosion around the cover. Truck has 147k miles and starting in August I will be driving it to Texas once sometimes twice a month. I have no problems taking a 15 year old truck that far, I just would like to prevent any problems. So would it be a dumb idea to change the gasket and water pump? Easiest way seems to pull the engine, and pulling the engine doesnt look hard at all.
