The Cadillac Northstar rarely exhibits typical blown head gasket symptoms

The most common symptoms for a Northstar, are unexplained coolant loss & overheating.

Often there is no white smoke from the exhaust, no water in the oil.                                                                                            

The more extreme cases show white smoke – which can still be repaired. (watch the repair videos)                                                                                                  

HISTORY:  The Northstar engine features a die-cast aluminum block and aluminum heads. The Northstar was designed to produce more power to compete with BMW, MBZ, and new luxury cars like Lexus & Acura. Installed in Cadillacs and other models from 1993 to 2010.        

CONS:  Coolant system problems have plagued the Northstar engine because of some design flaws that have never been corrected.      * Over time the steel head bolts and the threads in the aluminum block will begin to “stretch” and the head will seperate from the block, usually around 100,000 miles.                                                                                                                                                                                                               * The design of the thermostat housing also contributes to the overheating problems.

NORTHSTAR HEAD BOLTS

Often when a Northstar overheats, a mechanic checks the cooling system and finds nothing wrong. With no clear indication as to what’s causing the overheating problem a mechanic may suggest replacing various cooling system components, like a radiator, water pump or thermostat. Eventually, coolant starts disappearing again and the overheating returns.

If this sounds familiar, it is time to get a proper diagnosis. An experienced Thermalweld technician can provide the fastest and most cost effective solution to your problem. Let us help you properly diagnose your Cadillac’s overheating problem and ultimately determine if you have a head gasket problem.                                                                                                                                                                                  

To repair the head bolt problem requires a complete teardown, rethreading the holes & replacing the head bolts.               Some repair shops refuse to replace a Northstar head gasket, the ones that will, the starting price is $2,400 up to $4,500. Many suggest “just replace the engine”. Replacing the engine is in the $6,000 to $7,000 range.
