Cadillac Repair: 1995 cadillac deville engine problems, blown head gaskets, coolant levels

Question
Hello, I recently purchased a 1995 deville concours. The mileage is about 174,000 mi and I have gotten an oil change, a transmission flush, filled the car up with plenty of oil and coolant and I am getting the engine overheated, check coolant levels reading on the dash and the car will run hot and then automatically stop on its own....I am thinking it needs a tune-up also and I recently got into an automobile accident 3 weeks ago so that might have something 2 do with all the malfunctions being that everything is electrical...please help ASAP. Thank you very much

Answer
Sounds like a possible stuck closed thermostat or blown head gaskets.

NOTE: Did you add the SEALANT SOLUTION to the anti-freeze as recommended by the manufacturer when you flush out the cooling system. If NOT, Ask any auto parts store for the additive and install it .
