i have a question, im pretty sure u can do this, but can u take out the thermostat for instant cooling?

 

Yeah, you can, but its not recommended for several reasons. Mainly, you really do want the engine to warm up. Second, its designed, if tuned right, to run best in a narrow range of temps, and the thermostat keeps it there: no thermostate and you will get rather wild swings in temp when driving depending on speed, etc.

Finally, there are a few cases where removing the thermostate results in the coolant flowing too fast and the result is it does not warm up as fast or as much possible and . . whatever . . its bad. This was a problem ith early aluminum engines (e.g. Buick 215 cubic inch aluminum V8 in the mid 60s) and could result in cracked heads or blocks or something bad. I don't know if it is still an issue today.

 

ok thanks, i was gonna get a 160 degree one nyways.

 

If you're in a very cool area, you wouldn't want to go with such a cool thermostat. In fact, I've actually heard that a 160 degree thermostat is too cool anyway. The recommended operating temperature is around 180 degrees.

 

If you are going to use a 160 deg stat, and you have electric fans, you need to have the fans come on sooner, something like 180 deg instead of 220. Otherwise you will be running hot in traffic and cold on the highway. You should try to minimize temperature swings for the good of the engine.
