heat is the worse enemy of the engine, I installed a 180 stat and my tune has the fans come on earlier. always runs about 192, the highest in the last two summers is 206 !!!

Melting Slicks
Might also check the radiator side saddle tanks and the bottom of the overflow reservoir.
Both are plastic.
In my 01s life, both have developed hairline cracks (with the resultant coolant loss) and had to be replaced

What he said. If both fans don't turn on when you turn the AC on, change both the fan motor and the fan relay in the underhood fuse box. As the motors age they start using a lot of current and as a consequence the relays sometimes burn out.
