John,
I didn't replace my thermostat when I did my install as I only had 20K on the odo. & also because it was another $70 +/- I didn't want to spend...I hope that doesn't turn into a regret.
Just remember to take your time during disassembly & label everything (where hoses/electrical connections came from).
What Jolly Roger said is so true, I have a company van, but if I have service calls that don't require too many tools, I take the VX.
Also, my newfound extra large lead foot is killing my mileage,I've
seen some nasty addictions in my time, but this one is a real bad monkey...Oh well.
Anyway,best of luck w/ your install, do try to get the new throttle/cruise bracket before you start as it is much easier to install on the back of the s/c before it's bolted on.
Also, don't forget to "marvel" at the incredible vagueness of the
instructions.Oh yeah,draw yourself a diagram of how the serpentine belt is routed,if your memory is anything like mine, You'll be glad you did.
