Thread: Problem with radiator cooling

Tweet

Bigtruckdriver...You do not need a differant thermostat for every season, just install the 195 thermostat as per Dennyw said, and leave it in. I live in Canada and it gets extreamly cold in the winter and hot in the summer, and I use the same thermostat year round. With the engine running at 195 it also helps stop that little bit of oil sludge build up in the engine.

Like Dennyw said, the proper mixture is 50/50 as there is more than one reason for the antifreeze. First reason is for the coolant not to freeze during colder weather, second is that the antifreeze acts as a lubricant for the water pump, and also helps keep the inside of the block and heads from scaleing with rust, and thirdly it raises the boiling point of the water by about 15-20 degree's so it doesnt boil as fast as it would with straight water.

Running pure atifreeze in your engine is defentetly not a good thing, it will turn to jell when it gets cold. I am wondering if the engine not heating up has something to do with having to much antifeeze and not enough water. I have never run straight antifreeze so i do not know if that would cause the engine to disipate to much heat or not. You posted that your thermostat is fairly new, and since you have to drop 1/2 your antifeeze anyways, try doing what Dennyw said and just add the water to get your 50/50 mixture, then see what happens, if its ok, then great, if not, then as Dennyw said, change the thermostat. ( dont mind me, im just curious to see if to much antifreeze will cause the engine to not warm up so i will know for next time i come across that problem.. )
