Hey guys, i d like your opinion on what to start repairing on my diesel mule.
Its an 03. The Mule just started leaking coolant into the oil. I have a foamy stuff under the oil cap and on the dip stick. i drained the coolant, removed the water pump and i see a little rust in side the head. could this just be a gasket problem on the water pump. or a bad water pump? or head gasket ? Any thoughts on where to start.
