Thread: Thermostat on fuel injection motor?

I think I found my answer on the 10 page of google and then 3 pages in off of the link,lol.


Automotive engineers who get paid to “tear up” engines in the laboratory tell me they can destroy an engine quicker by running it at 160 degrees. This is due to the engine not getting hot enough to evaporate the acids in the crankcase. Your trucks engine requires 195 degree thermostat, nothing cooler! Your trucks electronics are calibrated for the engine to run at this temperature. Besides effecting fuel mileage you are promoting premature transmission failure. Running a too cool thermostat will contribute to “crankcase sludge” in your engine. This will cause your trucks engine to smoke and use oil prematurely. This is why older cars engines of the 1960’s and 70's wore out and smoked by the time they had 100,000 miles. Running the engines too cool with inferior oil by today’s standards. So if you think you have an overheating problem you need to make sure that it is not a head gasket problem. To verify the truck can cool down when it is hot, just take a water hose to the radiator while the truck is running. If the temperature gauge goes down then you have a problem with the fan or radiator. If it still gets hotter and won’t cool down then you have a head gasket (or cracked head) or the wrong water pump (turning backwards) As to the A/C system keeping R-12 as the refrigerant is the smart thing to do in the long run. R-12 may cost more than R-134a. In the long run it will do a better job keeping you cool and you’re a/c system lasting longer.
