    I just placed an alluminum racing radiator in my blaze and was wondering about the temp. Usually I would run aprox. 150 degrees average engine temp under normal operation. Now, however, with the new radiator I am running aprox. 102 degrees. My question is, could running cold like this have any long term negative affects on the 6.2? I know there is no thermastat in the truck, being in Cali. I really don't need one. But could the absence of back pressure in the system affect the pump? ------ I am always looking to learn. You guys are the best teachers I have found.

    Yes, too low a temp can be bad. Diesels "slobber" at low temperatures like excessive idling/running with no load. Fuel will contaminate your oil, sometimes you can see the fuel (oil-like) leak under the exhaust manifold where it mates to the head. Without sounding like your dad, put your thermostat back in. Members of the DieselPage swear by the RobertShaw brand, minimum of 160F, 180F for colder climates.

    Put your thermostat back in. If California cars didn't need them, then I would think the manufacturers would save themselves a few pennies and not put one in. Low operating temperatures will increase emmisions, decrease mpg, and considerably decrease engine life.

    My truck has not had a thermostat for who knows how long. It was obviously removed by a past owner. I plan on putting one in soon, expecially now that the temp is running so low. Thanks for the info.
