Buick Lucerne Problems

Engine Overheating Due to Leaking Headgasket on Buick Lucerne

Problem Description and Possible Solution

Overheating of the engine may cause the cylinder head to expand, severely straining the head bolts and damaging the threads in the engine block. This commonly results in a blown head gasket. Our technicians tell us the engine block threads must be repaired before the cylinder head is reinstalled.

this buick Lucerne is a cxs northstar engine 4.6, the engine run fine on the highway at a high rate of speed but in the city at normal speed 34-45 mph it would start to run hot, and when the engine is running in idle. The car now have 60000 original miles on this car and only been service by the dealership and this car was purchase new. I don't want to believe that is car have a blown head gasket problem. I would like to know is this engine have a recall on this north star 4.6 liter engine because the motor have lots of service repairs. it's still running hot and I need some help with problem.

Thank you very much.
