skyview Posted February 21, 2004 Posted February 21, 2004 I recently had my timing belt and water pump changed and now the aux fan appears to be on all the time. Before the maintenance, I didn't hear the aux fan running at all. When does the aux fan suppose to run? Thanks ...
skyview Posted February 21, 2004 Author Posted February 21, 2004 I may have misquoted the fan that I am referring to. It's the fan that's between the grill and attaches to the outside of the radiator (away from motor).
jzz30 Posted February 21, 2004 Posted February 21, 2004 mainly when the ac is on and when the motor gets a tad on the hot side
obergc Posted February 21, 2004 Posted February 21, 2004 I don't know about the 95's but on a 93 if the electric fans were running all the time I would be checking for an electrical connector located on the bottom, left side of the radiator being disconnected. If you disconnector the connector, the fans will run all the time.
VMF Posted February 21, 2004 Posted February 21, 2004 check all the sensors, you might connect it incorrectly or didnt connect it at all. but in 95 model that fan should be always on.double check all the sensors and you might check for error codes as well.
skyview Posted February 21, 2004 Author Posted February 21, 2004 VMF ... Are you saying the radiator fan should always be on?
VMF Posted February 21, 2004 Posted February 21, 2004 the one inside yeah, its a tthermal clutch fun and its always on while the electrical one outside that tis located on the AC condencer should not be on all the time
tansupplyman Posted February 21, 2004 Posted February 21, 2004 What is being discussed??? The engine fan or the electric aux fan??? :o
jzz30 Posted February 22, 2004 Posted February 22, 2004 i think he means the ac fans they look like they are for the radiator
UCF3 Posted February 23, 2004 Posted February 23, 2004 Two Electrical fans should only be one when the AC is on, and when the radiator requires emergency cooling. Engine fan should always be on, since it's operating your engine. If your electric fans turn on, when the AC is not, it's a good indicator that the coolant in your car isn't as good as it should be.
wandawoods Posted February 23, 2004 Posted February 23, 2004 this topic had been discussed in detail in the past, but the thread was lost in the big crash. my AC fans were on all the time after timing belt/water pump replacement on Sept/03. the cause was the mechanic forgot to connect the ac fan temperature sensor. after recennected the sensor back on, the 2x AC fans (outside radiators; 2 for 94 LS) have been operating normally since. they will only turn on when AC is on, and off in 10~20 seconds once AC is off. check the sensor as indicated in the picture.
VMF Posted February 23, 2004 Posted February 23, 2004 95 version has only one fan but the sensor is still in the same position
