As I had written in a previous post, after I bought this 88 Ranger I took it in to be inspected, and the mechanic found coolant from the radiator in the engine oil. Took it back to the dealer to have the engine fixed under warranty, they found a cracked cylinder head.
Dealer replaced the cylinder heads, did a valve job, etc., and then when testing it, he found that they now improved (no longer leaking) cooling system, having more pressure, had opened a seam in the radiator which was leaking. Dealer had him replace the radiator.
On driving it back to the lot after the radiator, replacement, mechanic found steam rising from the dash. I guess improved coolant pressure was too much for the old heater core. The dealer had the heater core replaced as well.
My warranty specified dealer pays half, I pay half. Total cost was $1200, so my share was $600. Not too bad for this amount of parts and work?
