What's the normal temp for the 603 engine when in traffic? Is usually hit 110 if it's bumper to bumper. I don't think this is normal. If I rev teh engine a little, th temp goes down to about 100. Any parts I have to change? Hoe do I know if the VISCO CLUTCH is still working, can this be adjusted or replaced?

I also heard somone say that there is a THERMO SWITCH which controls the AUX fan so It can turn high speed earlier?


Thanks!
