CTS dampening

[Dave Zug]

I'm not going to say the silly things like:

Make sure the air deflector is on below the radiator
Make sure BOTH speeds of the fan are working
Make sure a hose is not collapsing under pump suction (no 'spring' inside?)
Water wetter actually works (??)
Small race crank pullys (like the one you *may* still have) are buggers in
the heat, and at stop lights and the taco bell drive thru.
Lean condition?
Hot trans cooler up front?
foot-on-the-floor-eye-tis?

Nope - Ain't gonna say it... Dont need to  ;-)

Oops, this ain't the GN list?! sorry, flashbacks.
