Hi guys:

Ok. I took it off the mountain and drove back up the mountain. The temperature guage maintained at way less than 80 degrees as I coasted down the hill.

When I drove back up the hill, at about half way up <1 km, the guage hovered just above 80 degrees. I assume this is when the thermostat opened up fully. As I approached my house at about 1.5 km, the guage jumped to over 100 degrees and then dropped down to just above 80 degrees. (It's a cool morning here in Vancouver.) So, I couldn't get it to over heat today.

When I got home, I pulled into the garage, popped the hood and turned off the engine. The fan IMMEDIATELY stopped spinning when I turned off the engine.

So...I guess this means that the fan clutch is ok.

My next step may be to flush and refill the cooling system?

Any other suggestions?

Thanks so much for your help.

This is kind of like medicine.....consult that is...

Brad.
