So I need some help guys. The trooper is running hot. (above the half way mark). Strange, when it warms up for the first time it climbs (temp gauge) to almost 3/4 then comes down after a minute or so. Then just stays hot. I think this is killing performance and my engine. Is there a way to get it running cooler without buying amymore parts right now? I probably need a radiator and this after market thermo is probably acting up. However, I need to drive to work tomorrow about an hour away and I dont want to run it this hot. Is there a way to get it running cooler? Someone said they run straight coolant with no probs and it runs 20% cooler. Is this ok? What about drilling a hole in my thermo? Any acvise would help. Thanks guys! Im kinda up a creek right now.
