read through the other forum on overheating to find out what all I did... to answer your question though... you are overheating on the trail because your engine is working harder at slow idle speeds and your fan isn't moving enough air. It's a little pricy but an electric fan (mine is from flex-a-lite) will do the trick. You could also try installing a lower temp thermostat (180 degrees).

Cracked head or bad gasket will show itself in form of steam or excess condensation at the tailpipe, discolored(greyish) foamy engine oil or a slimey film inside the radiator.

Im guessing you replaced the radiator for a reason. Did you replace the hoses as well? Old hoses can and will bloat as they get old and cause a pressure drop within the system which in turn leads to overheating.

A couple of simple things you could try. Retard the timing a degree or 2. Use Water Wetter, it works. Gunk has a product called COOL that works well also.

Good luck

All that should help, but since 97 is OBDII, I don't think you can retard or advance the timing...it's all controlled by the 'puter. Wink
