OVERHEATING ISSUE? on 1998 Cadillac DeVille

My 98 Deville is starting to overheat and loose coolant as well. I am sure it is the head gasket because my car symptoms are similar to others who have experienced head gasket difficulties. Would this problem resurface if the timeserts are installed at a Cadillac dealership? I also have an oil leak, which I think is associated with the head gasket problem. Would a bad head gasket make the Northstar leak oil as well? I had a 98 Dodge Neon and the head gasket was bad on it and it leaked oil as well. After the Neon head gasket was repaired, it stopped leaking oil. My car only has 79,000 miles on it, so I think it is worth the repair. Does the transmission usually fail after the head gasket goes bad? Do you have any advice on what I should do?

Sorry to hear about all of these problems. It does sound like the head gasket, and that may be the source of the oil leak, but it may be something else. Regardless, you are going to need a major and expensive repair. My best advice is to have a good technician who really knows Cadillacs check out the car and give you some advice based on it's condition. This doesn't need to be the dealership, and you may save money elsewhere with someone who works on older cars. Check out the common problems page for this car on RepairPal to get an idea of what else could go wrong. The transmission shouldn't develop problems because of the head gasket--they aren't related. http://repairpal.com/cadillac-deville-1998/common_problems
