NIssan Serena Turbo-Diesel
 

Hi All:

I am driving a 1997 Nissan Serena Turbo Diesel and having some overheating problems. I have taken out the thermostat (car is running in Jamaica), changed the sensors, rodded out the radiator, bled the system, car is still overheating. But the water is boiling only in the expansion bottle and the water in the radiator is relatively cool (hand warm). What's going on? Anybody with an idea? By the way car is running smooth so I hope that it is not the cylinder head. But I am open to any suggestion. Thanks
