Hey guys,


I have no idea whats up, but on occasion I can hear a groaning from the engine compartment, and what sounds like a low whine when I'm on the highway.

My thermostat is wicked amounts of wacky; It'll peg itself at 120 and jump down to 60 on a whim.

I assume the first is my fan clutch? Is that a tough job to do for a light DIY-er?

Also I've read it's best to do the thermostat and a coolant change at the same time; what do you guys say?

the 560 has officially gotten to 213,000 miles today, still running strong (I'd prefer to keep it that way).


Thanks a lot,


Carlen
