Got another question, I'm planning on changing to a 180 thermostat. Will this help with the heat issue, by lowering the temp of the entire engine? It sure does get hot under that hood. I know the fan will still not kick on until 195, so it will technically ''overheat''(but not really, thats what it was originally) until the fan kicks on or I get moving again.
Putting this thermostat in won't crack the head will it? I mean, if it's up to about 200 and that cold water comes rushing in cooling the head down at a rapid rate. I know it's bad to have something cool down quickly, a vice versa heating up causes metal to crack. But will only 20 degrees do that? I thought it was only extreme changes in temp cracks things, but tell me if I'm wrong. I'm not in stopped traffic very often at all, but I'd like to know anyway. That ECU i'm going to get says ''revised fan schedule for better cooling'', does that means it will kick the fan on sooner? Cuz that would be great if it does. Thanks.
