I know this has been discussed many times but my car is over heating. I took it to my mechanic, he said pull the thermostat and run it without one. I did and the car ran fine and the temp gauge went up about half way. Listening to advice of many on the this site I felt I had to have a thermostat (why do I have to have one if I'm not driving in the winter?) so I put in a new 180 now it doesn't run as hot as it did with the old one. Obviously my old 180 thermostat was bad.With the new thermo the temp gauge almost tops out but not all the way (a little over 3/4) like the old thermo. Ok so I can do one of two things, put in a 160 (some here have advised not to do that) or I can take my mechanics advice and run without a thermostat (I figure we have a thermostat in there for some reason but honestly don't know why). So what do you guys think, run the 180, 160 or nothing? BTW I have the stock fan shroud and a new 3 row rad.
