Coolant overflowing out of overflow tank? OVERHEATING!!!
I just recently replaced my engine with a brand new remanufactured engine...I've put about 600 miles on it...
Runs awesome, but now I've run into a overheating problem, first thoughts was thermostat & rad cap so I replaced those & i'm still having the same issue.
After about half a mile of driving the temp starts going up, it's pushing coolant into the overflow tank & overflowing if it gets too hot. Once you let it cool, it all goes back into the radiator leaving my overflow tank at MIN
My radiator fans are working, so could it only be a waterpump?
Really frustrating spending $4,000 on a new motor & I'm running into other issues...
The place I took it to, all they work on is 350z,g35, & vq35 engines so I'm sure they knew what they were doing, I don't think it has anything to do with them putting on something wrong...
What could it be?
