Looking around the forum and finding a receipt from exactly 3 years ago and 30K miles for a water pump and hose replacement on the 1996 Discovery SE7 gives me pause. Is this normal? Additionally, I just found out that the "number one rated," by area customers, service center that did the job did NOT put sealer on the two long bolts that pass through the water jacket and the top bolt is immovable. I don't see how soaking with penetrating oils or heat will loosen this bolt if corrosion has it seated in the block where nothing can get to it. Warranty was for "2 year/24,000 miles"...
