I have replace the gaskets on the cross over tube (fun) as will as Radiator and cleaned the whole cooling
system after I found green coolant , ( radiator did have a small leak on the tank.)
The best I can tell I'am not having any head gasket problems and the car has never been hot.
My question is , Well all the head gasket fail on these cars?
Its sure not the easiest think to work on, as you all know,
Not interested in the head gasket replacement , Sell IT Keep IT Please advise Thanks

 

Hi! I have a 1999 Cadillac Fleetwood Limited (Which is basically a stretched Deville) and I haven't had any problems with the head gaskets. The car has 132,000 miles on it and it still runs beautifully. I actually haven't had any major issues with the car at all besides replacing sensors that go bad over time. In my humble opinion, I don't think there is any reason for your car to have head gasket issues as long as you maintain the engine properly and replace fluids regularly. That is all I have done to my car and it has been one of my families' most reliable vehicles. I hope that this helps!
