Fri, 18 February 2005 02:47 If you want to run your car a FEW degrees cooler (like 5 degrees) you'll get a slight power increase. You'll also get a similarly slight emissions increase. I don't believe any cars in this thread run UNDER the thermostat temps. If they do, then the thermostats are faulty. A car should run on or just over the thermostat temp. If its under, then your not getting enough water circulating round your block (no flow) and you'll get hot-spots and cause a BHG or worse. Running thermos full time is a bit silly (depending on car etc.), you'll always have COLD water entering a HOT engine instead of WARM water entering a HOT engine. COLD water into HOT engine = cracks. Which is also why you don't put cold water into a radiator when you've just changed the thermostat and the engine is still HOT. Points of interest: - Holden commodores running temp is around 100 degrees (maybe higher, but couldn't find it on google). - 1UZ-FE engines have the thermostat in the hose between engine EXIT and radiator ENTRY. They have a nifty recirculate pipe so there are no hot-spots when the engine is warming up. [Report message to a moderator]
