Heza Posted October 15, 2003 Report Share Posted October 15, 2003 ok...im trying to figure out some stuff cuz i am mystified. -the main radiator fan is on the passenger side and the auxillary is on the driver side right? cuz my 'aux' fan starts up first. i changed out my coolant sensor thinking that was the problem, but no help. -when does the first fan start to kick in? -could my water pump just be going out? cuz my coolant was a little low, but i just flushed it out and put new stuff in.

99RegalGS Posted October 15, 2003 Report Share Posted October 15, 2003 Your computer controls the fans baced on engine temp and if the A/C is on. As far as which fan is which, I would guess the one that starts up first is the primary. Quote Link to comment Share on other sites More sharing options...

99RegalGS Posted October 15, 2003 Report Share Posted October 15, 2003 The thermostat is a mechanical valve that opens when your engine gets up to a certain temp and allows the coolant to circulate through the radiator. The fans kick on when the radiator isn't cooling the engine enough. Ex. stopped at a stoplight. Quote Link to comment Share on other sites More sharing options...

grandprix104 Posted October 15, 2003 Report Share Posted October 15, 2003 should be the other way around if one isnt coming on right try running some prestone radiator clean through it. for some reason this worked wonders on my car. My guess is the sensors were so gunked up they couldnt tell the temp properly but as soon as i put that in it for a few days it worked great.

Yeah primary is on the drives side, secondary on the left. First one comes on at 220* 2nd at 227* Quote Link to comment Share on other sites More sharing options...
Heza Posted October 16, 2003 Author Report Share Posted October 16, 2003 well, maybe my temperature guage is off then because on my car it kicks on around 230ish...of course the temperature guage on the 94+ prixs is sort of interesting to figure out unless you read the lines with the temps right next to them. i don't know the ratio to the guage...eh...gonna hook my car up to a computer and figure it out for myself sometime.

SmokesGTP Posted October 16, 2003 Report Share Posted October 16, 2003 Yeah it doesn't make sense. I hate that gauge it gives you a within 20 degree approximation. Quote Link to comment Share on other sites More sharing options...
PaPaPooh Posted October 16, 2003 Report Share Posted October 16, 2003 IIRC when i asked the instructor for A/C about A/C and fans he said the aux fan kicks on when running A/C i thing you got a freak on your hands Heza!! Quote Link to comment Share on other sites More sharing options...

PaPaPooh Posted October 16, 2003 Report Share Posted October 16, 2003 does it kick on with A/C off first maybe im confused now hell i don't know Quote Link to comment Share on other sites More sharing options...
Heza Posted October 16, 2003 Author Report Share Posted October 16, 2003 does it kick on with A/C off first maybe im confused now hell i don't know itll kick on by itself when the engine gets shitty hot...but the primary will turn on if not on already when AC is on....if engine is shitty hot and the primary fan turns on....then turn AC on....the aux turns on Quote Link to comment Share on other sites More sharing options...
cutlassdude96 Posted October 17, 2003 Report Share Posted October 17, 2003 the AC has to be on max and fan on high for the aux fan to turn on Quote Link to comment Share on other sites More sharing options...
Lee Posted October 17, 2003 Report Share Posted October 17, 2003 There are two water temp sensors. The fans run by the one near the thermostat, under the front part of the throttlebody. The dash gage is run by one with a pigtail (like the O2 sensor) behind the motor, driverside up high, near the EGR valve. Quote Link to comment Share on other sites More sharing options...
