some vehicles have 2 fans, one for when the air is kicked on and the other fan for normal driving so there is 2 switches.
The computer uses the two wire sensor near where the upper radiator hose attaches to the engine to decide when to activate the radiator fan.The computer uses the two wire sensor near where the upper radiator hose attaches to the engine to decide when to activate the radiator fan.
I assume this readiator is in a non-turbo car. The fan units are attached to the radiator itself. Once you remove the whole radiator fans and all it will be much easier to work on. The radiator is held in place by two clamps at either top side of the unit. Remove feed and return hoses, and unplug two temp sensors at bottom of radiator. Remove trans cooler lines (if auto trans). The fan units are secured to the radiator by four screws.
The problem you seem to be having is the cooling temp sensor. It controls the fan speed which has two speeds. Try that.
The relay is more likely to fail than the fan. Easiest way to check is to disconnect the electrical connection to the fan and hook it up to two substitute wires ... one to the battery and the other to a ground. If the fan runs, you know it works, so your problem is either in the relay, the wiring, or a temperature sensor.
There are three coolant sensors installed to a 1989 Toyota Corolla 1.6 GL. One is a thermostatic valve switch that controls vacuum lines and is located near the passenger side of the carburetor and below the intake manifold. This can be identified by the hoses connected to it. The two other coolant sensors are located immediately before the big water hose leading to the radiator (upper hose). These two sensors can be identified by their electrical connectors. The bigger terminal is connected to a relay that controls the operation of the radiator fan. The smaller terminal is connected to the temperature gauge at the instrument panel.
By the radiator fan on the battery side. Visible leaning over front bumper into engine bay looking back at radiator fan. Black box with several wire harness connections and two screws.
The cooling fan relay on the 2004 Chrysler Sebring is in the engine compartment fuse box. There are actually two cooling fan relays in this fuse box. One is a high speed radiator fan relay and the other is a low speed radiator fan relay.
Remove the radiator cover the connects to the frame. These are connected by 4 bolts.Unplug the radiator fan.Remove the top two clips that hold the radiator to the fan.Remove the bolts on the sides of the fan.An instructional video explaining how to remove a radiator fan from a 93-97 Dodge Intrepid has been included below.
the relay should be next to the fan on the radiator shroud The radiator cooling fan fuse is #1 on the fuse box. The 1988-1989 Cabriolets have a two-stage cooling fan relay, which is mounted to the left fender in front of the battery.
there are roughly 10 bolts.rather you have electric fans or not iam not sure. i have a regular fan so ill tell you from there. First you should take the fan off it helps. (OOpps drain the radiator!!!) undo the fan shroud, 2 bolts, pull it out and set the fan and the guard to the side. take the plate off of the top of the radiator.,4 bolts, take the grill off ( two bolts in between grill slots) then take the two bolts out of the radiator support bracket and then the radiator should come right out. good luck.
WHICH fan relay? There are three fan relays, located in the ecu box on left side, under the hood, just behind the battery. The aft fan is for the radiator fluid temp control, the two fwd fans are for a/c related temps....good luck
Dead fan motor, bad connetion to fan motor, faulty swith on radiator. To check, pull connetion to fan apart, this is a two spade connection found close to fan. Run a live wire from battery to connection and another wire from connection to negative pole on battery. If fan starts to spin, the motor is fine. This test can also be done at the thermostat switch on the radiator. Fault must be at radiator switch. This switch is located half way down the right hand side of the radiator. Drain radiator, remove switch, replace switch, refill radiator, bleed cooling system. Problem solved.
