Hi.
I know is tricky to fix these engines once overheated.
any point trying to resurface the head and reinstall the head gasket or just buy another engine?
Thanks
Describe the overheating event. How long was the engine run after you noticed it overheating? Did you see white smoke out the exhaust? Does the engine run? Shutting off the engine right as it starts to overheat can save it.
Is the electric fan on at high speed, did it loose coolant? We haven't had to replace one engine because of overheating in this model
Right. The N52 engine will usually turn itself off before it turns into a boat anchor. I have never replaced a single N5x engine due to overheating.
