I've actually decided to start very basic, I've picked up another bottle of WW and I'm going to try that first. The range of coverage for a bottle of WW is "1 bottle per12 to 20 quart system", I'm actually closer to 6 gal. or 24 qts. so I figure that being close to the limit of coverage, I may not be getting the full benefit of the product. @ $4.99 a bottle its jsut as cheap as a thermostat and easier to install. Anyway my approach to diagnostics is to first check all settings and make sure everything is within spec. So, we'll see if I need to spend another $4.99 on a thermostat after I test the car tomorrow.

Also on the subject of 160 vs. 180 thermostat I'm not sure I follow the logic. A 160 will open sooner however, the engine does not continue to run at 160. Most will continue to increase in temp to around 180-185 I would guess. A 180 will not open full until 180 however, both the 160 and the 180 are open full once the engine is at operating temp which as I said I believe is normally 180-185. Plus, most electric fan thermo switches turn the fans on at 195+ so the engines would seem to always exceed the 180 mark and the thermostat should always be open full. So,What is the benefit of running a cooler thermostat?
