I had to stick my hand down behind the radiator to make sure it was even blowing all.
They do have 2 speeds which come on at different stages. After I had the car tuned, I think the temperatures for the fan speeds were changed, my car SITS on 180* now and NEVER moves. I'm almost starting to think my guage is broken (even though it's a '98).
the fans are wired in such a way that they will first come on at 226F and go off at 217F. At this turn on temp, each fan gets 6v and turns at a slow speed. When the temp reaches 235F (2nd turn on temp) both fans receive 12v and turn at full speed. They are rather loud at full speed and pull alot of air. when the temp drops below 226F the fans go back to slow speed.
While the car will work just fine with these turn on/off temps, if you can, it is a good idea to lower them. i guess that is how ls1blur has his sitting at 180F...

ok. i when i replaced my stat i set the fans back to stock. went out today and reset them to 180 and they are once again coming on hard and loud. but there is still no back pressure in the system. it went from violent overflows to no pressure at all. still no leaks, just no pressure when i remove the cap. anyone had a water pump fail and have these problems before? still no water in the oil, however could my pressure issues be a bad head gasket?
i have posted this problem before, i just wanted to try and figure this out before i tear the top end off the engine.
