engine running cold
 
Finally got my jeep going,after blowing up my 327 I put in a chevy 283.Today we got or first snow in Minnesota,so i decided to go for a ride.I have an electric fan and an aluminum radiator and a 160 thermostat.All day long it ran at 115 degrees I dont have a heater or top so i'm not worried about that.I'm just wondering if a engine running that cold will hurt it.When I stop it goes up to 150.

Sounds like the thermostat is stuck open allowning colant to flow continuously. For $5 and 10 min. I'd change it. The engine heats up a little when you stop because you aren't forcing air through your radiator and your water pump isn't turning as fast.

The thermostat is not stuck.Today I also found out that you can drive with a detroit and BFG M/T'S on icey roads.Of course I wouldn't recomend going over 45 and watch out for those big rigs on corners.AAAAAAAAAHHHHHHHHHHHHH

Try putting in the correct temp thermostat for that engine. It's probably supposed to have a 195. I'll bet your problem will go away with the correct one.

Also, you should check the actual temperature with a thermometer in case the guage is not accurate.
Running that cool can cause long-term damage to the engine, since the clearences aren't at specs.
