What is this shop doing to repair Northstar engines?
There is common thought that Northstar engines fail and are very tricky to repair and reinstall. The center of gravity for the failure is a blown head gasket.
I cam across this vendor in California that implies he can repair a Northstar, at a much lower cost than rebuilding the engine. I am wondering what he is doing, and does his process reduce the exposure that is implied in replacing a Northstar.
""Do you have a vehicle with a Cadillac Northstar engine it. And you have a blown head gasket or a cooling system problem that cant be figured out. Well I can help. I can repair the head gasket without a rebuild please read below and contact me for more info.
The Northstar condition:
The Northstar'* rarely exhibit typical blown head gasket symptoms. Initial overheating issues can usually be traced to component failure and repaired. This corrects the problem for a while and the first indication of some residual problem begins with a low coolant warning. The car runs great so you add coolant and don't think too much about it. You check for leaks under the car and everything looks good. Your mechanic checks the cooling system and also finds nothing wrong. The coolant seems to have just disappeared. As the distance between low coolant warnings gets shorter and shorter you begin to have episodes of overheating. There is little time from between the low coolant warning before the temp gauge starts to rapidly climb. Usually this sudden rise in temp is followed by a rapid fall in temp (back to normal). This is again followed by a rise in temp, but this time it doesn't come down.
When a car overheats it is only logical to conclude that some component in the cooling system has failed. Although there is no indication of what is causing the problem, mechanics frequently suggest replacing the water pump. When the engine still looses coolant and overheats the frustration mounts. Next you replace the thermostat, but no luck. Finally, you install a new radiator but the coolant loss still persist.
With nothing left to replace your told that you must have a blown head gasket and replace the engine.
I can fix this without a rebuild or new engine. I can save you thousands of dollars and save your car. Please contact me for more info.
