Question about 1996 Cadillac Seville CA Value
I have a 1996 Cadillac SLS. It runs hot, loses coolant and emits thick white smoke from the exhaust. I see very little coolant on the ground therefor I assume it's sucked into the block. I also have a oil pressure problem. I love the car and want to keep it, but I don't want to buy another engine. What are my options?
The Problem, My friend, is a leaking oil cooler. this item is mounted, inside the engine, under the intake manifold. The cooler or the connections are bad. Coolant flows through the cooler, if it brakes then the oil will contaminate your coolant and make a mess.!! Have it checked. Must times is the seals at the pipe to cooler flange connector. will need new seals.. Hope this helps.

First determine where coolant loss comes from. I would not continue driving, till that step is isolated, or further damage will be done

how many miles are on it? if you have over 70k the head bolts may have let loose and allowed the head gaskets to leak they all do it

OK, check that the 2 fans are turning on when it gets to operating temperature. If not, replace the 3 or so relays that control the two speed fans on your car.If that doesn't solve the problem, then you may have to buy new fan motors and also have the harness replaced if necessary to make it cool reliably.
I had this problem on a 1997 Cadillac Deville Limousine that overheated over 157 deg. F and went into its limp mode for cooling the engine off by allowing 1/2 of the cylinders to circulate fresh air into the engine in case all antifreeze would leak out or the car would overheat.
Don't run the Northstar engine too long, more than 45 min. at a time in this limp mode.
Good luck on this repair of your Northstar Engine.
