Hi,
I have a 98 Navara ( Frontier ) Diesel Pickup, 2.5TDI engine and since a while now I have to refill my coolant after every trip. Apparently the pressure becomes soo high that the overflow valve can't take it anymore, and it sprays out. I've already done the following:
- changed the radiator , it shows the same reading, 0.9 bar
- tested the air in the radiator after a test run for carbon monoxide, with a tester, which would show a opening from the gasket into the coolant, leaking compression. This test came back negative. There's no oil in the water either, so I'm out of guesses... Any idas, hints, suggestions?
