What causes Northstar head gasket failure?
There are three ways the head gaskets can fail on a Northstar. 1- exhaust gases blow into the cooling system under load, such as when you climb a hill or pass someone. 2-coolant gets into the cylinders and you leave a trail of white smoke behind you. 3- coolant gets in your oil or vice-versa.
Is the 4.6 L Northstar a good engine?
Registered. When we had the Northstar Sevilles/DeVilles come in for service, we found the occasional oil leak from the pan, and water pumps are a frequent purchase for some. Overall, performance from these engines, as long as all routine maintenance is followed, is pretty decent reliability-wise.
Why do Northstar engines overheat?
The thermostat gauges the temperature of the engine to control the flow of coolant into the cylinder block and radiator. A faulty thermostat might not open, meaning coolant won't flow. This in turn will cause the engine to overheat. ... If the radiator hose is not hot, the thermostat might need to be replaced.
Do all Northstar engines leak oil?
When Does the Oil Start Leaking? We wish we could tell you that your Northstar engine will never leak, but our experience tells us otherwise. There's no way to avoid this. It's understood that every Cadillac Northstar 4.6 engine will start leaking oil at some point, regardless of the Cadillac model that you drive.
