Thermostat
Ok, I know it's a dumb question. What is the outcome when a Thermostat goes bad or if it's going bad what will it do or not do? Sorry, I'm trying to learn and have bought a book to do my own maint. but, just need some insight here.

If it won't open, the truck will overheat as it warms up, instead of getting to a warm temperature. If it will not close, the truck will take forever and a day to warm up, or not warm up at all, depending on the outside temperature. When is the last time it was replaced?

I run a 180* during the summer, 198* during the winter (still runs 190 or so during both seasons).
I do replace mine every season though...new one for the summer is going in when the headers do.

Cool, thanks for the information everyone. That might explain why w/the most recent temp's warming up outside my temp in the truck has increased. As I stated I have a 90 Ranger w/a 2.9. Should I just go to my local parts store and give them that information and ask for a summer thermostat? Thanks again.

Indeed. You can go to the parts store and ask for a thermostat for the 2.9L, then when they give you the selection pick a mid 180*s one.
The temperature of the truck depends not just on the thermostat, but where you live (how hot/cold is it outside), the distance you travel (does it have time to fully warm up), and the condition of the cooling system in general.
The 2.9L engine is NOT one you want to overheat, it's quite prone to head gasket issues and cracked heads if it's overheated.

That may be true for your f150, but as zach says, those 2.3L engines are prone to hot running problems. Hopefully, other guys with the 2.3's will post in with their experiences. The thermostat you run depends on the weather. If it's hot in your region, the radiator isn't as efficient at cooling. Notice that the thermostat position is pre-radiator and reacts to the temp of the coolant leaving the engine, not entering the engine. In warmer climates, the return from the rad is warmer than in cooler climates. An engine with a 180 T-Stat in a Canadian summer will run cooler than the same engine with a 180 T-Stat in a Georgia summer.

Right. I have the 4.0L V6 which isn't a fan of overheating, and I live in Texas where 110* days during the summer are perfectly possible. I only run the 180* thermostat during the summer, and it will still hit 190-195* on really hot days with the A/C on. It was the only way I could keep it from overheating during the summer with the A/C on however. During the winter I run a 198* (stock replacement) thermostat, and it typically runs around 190*.
