I have a 1997...

I have a 1997 Cadillac with a North star engine that I had a mechanic repair the head gaskets.it still overheats.He claims the pellet we added to the new coolant was not necessary and gunned up the system causing the overheating.Do you agree..

Mechanic's Assistant: How many miles on the car? How has your mileage been lately?

101000 .can't drive it mote than 2 miles.It overheats.

Mechanic's Assistant: What is the model of your '97 Cadillac?

Sedan DeVille

Mechanic's Assistant: Are you fixing your DeVille yourself? What have you tried so far?

I had a mechanic fix it.

Hey how are you , I will try to help you with this issue ,
Did he replace the head bolts , the head gasket job on this car requires new head bolts and rethreading of new head bolts and will have new sleeves inserted ,if he only pulled heads and send to machine shop and installed new head gasket only with out buy the bolt kit and the procedure to do it ,it want work, what happens is when the car start to over heats those head bolts will stretch and cause a gap in the gaskette making it over heat again, it is common problem if repair shop has no experience doing this job .You are very welcome :)
