My Avalanche over heats when I tow but only up.
2002 CHEVROLET AVALANCHE

Radiator is too small. For towing, you need a bigger radiator to keep the motor cool.

I had the same problem with the same avalanche. I replaced the fan clutch and everything works great.

Fan clutch has an effect at idle. It is turned off above idle
