Re: 160 or 180?????? (myscx)
Do you drive at all when it's cold up there? If so, stay with the 180. If you have the ECM reprogrammed to turn on your fans early then maybe 160. I personally would rather use the 180 which I have because it gives me a good compromise between summer and winter temps. Besides, your car's emmisssions is designed to work at the 200-210 or hotter range. Now, if you're running a 383 with no emissions or exhaust, go with the 160. If you want a heater, stay with the 180. Just know that what was said earlier about the thermostat openning and staying open does not affect the operating temp of your car if there is a cooling problem. :chevy

Re: 160 or 180?????? (Strick)
On an LT1/4 the engine temp stabilizes about 10 degrees warmer that the thermostat setting, probably due to the reverse cooling and the relative positions of the thermostat and coolant temp sensor.
So a 160 thermostat runs about 170 degrees in my 95 LT1. The stock thermostat ran over 190. Of course in hot weather, the thermostat temp is irrelevant. Our winters get down to 20 or so, and the heater works just fine with the engine temp at 170. The oil temp stabilizes about 20 degrees warmer than the coolant, so 190 or so minimum.
I reset the fans to come on at lower temps to take advantage of the lower thermostat temp.

Re: 160 or 180?????? (myscx)
I have a 160 now with a thermomaster chip (Hypertech). I was just told that the motor will not burn off the moisture and that the motor needs to run hotter or it will put twice the wear on the engine. I do not drive it in the winter so no problems with heat, just worried about putting more wear than needed on the motor. :confused: :( its a 1990 L98 :thumbs:

Re: 160 or 180?????? (myscx)
I had a 160 on mine for a while, didn't like how the temps were and went to a 180. IMHO I like it. Doesn't get overly hot and if you can get going it will bring the temp down to 185 which shuts my rad fan off.

Gee does water evaporate if its 160 degrees outside, or only if its 180 plus ?
I run chip and 160 stat and seen no signs of moisture in oil. :smash:

The more important question is whether or not the oil tem can get high enough with a 160 stat.

I have a 160* stat in there and lately my oil has been running 200* on 80* days. On cool nights though it is in the 183* area. Coolant stays in the 170-180* area.

Re: 160 or 180?????? (mitchcole)
If you put water and oil in a container heat it up to 160, the water will stay there forever. Water needs air to evaporate at temps below boiling. If there is an oil barrier, it just won't happen. If you bring it up to 212, the water will boil and the vapors will go through the oil to the surface.

I Use the 160. On the highway with the stock motor it used to run very cool, and pulled better near redline. City driving and lower speed driving the temps are about the same, especially when its hotter outside.
