The ECU signals the radiator fan to work at the precise time. See Contact Test in Step 1. Normal engine temperature is achieved within 30 minutes of idling, and within 45 minutes, sufficient heat should build within the cooling system to require additional cooling via the radiator. Older Volvos had a separate water temperature sensor at the radiator. Fig. Cooling Fan Switch - Radiator. Connect PicoScope Channel A. to the fan switched earth circuit. You'll then hear medium for test 1 and high speed for test … The coolant temperature fan switch/sensor at the bottom of the radiator is new and works as it should in another similar Camry (I switched it out to test). It's not under "cooling system" or "troubleshooting", it's under "switches" page 19-10. This is a DIY test with No T4 TESTBOOK required !! In these designs, the fan switch is a little more complicated than on single-speed fan systems, but instead of supplying current to a relay, the switch feeds power to resistors. Check that the cooling fan stops. General E46 Forum Use manufacturer data to identify the cooling fan circuit functions. Remove the radiator fan relay from the fuse and relay box on the fender well. Fan will work by jumping straight from the battery or by jumping the two wires together that are plugged into the sensor on the radiator.According the my … In the above schematic the item number 5 is the Fan Motor Assembly part number 19030-MAA-023. The radiator is typically inaudible from the driver's seat, so a simple test to see whether it is working correctly, is to switch on the engine and allow it to idle for 45 minutes. If you can do this test, I can fruther help you troule shoot this circut. They're right under the thermostat housing, as others described.

The inputs the computer uses to decide how fast to spin the fan are: Radiator outlet temperature Catalyst temperature (calculated temperature) Vehicle speed Battery voltage A/C pressure (calculated pressure) To troubleshoot: check computer for any set codes unplug the fan connector and test for voltage on the two large wires. If the fan starts to spin, the motor is good. 1 - Radiator Cooling Fan Relays Testing The fan can be tested with the engine on or off (but preferrably off), by removing first the "Fan Low" relay, and putting a test lead, or a heavy wire jumper between relay socket contacts #30 and 87. Connect the high amp clamp to PicoScope Channel B, zero the clamp before inserting into the fan power supply circuit. If it stops working, your engine could overheat and be damaged. Switch must be bad. [If you can't find the fan circuit test lead near the ECU, you may not have the coolant recall fan modifications.] It’s the fan motor that makes the radiator expensive. ( Note: if the circuit is computer controlled a delay could be programmed into the operation of the accessory, additionally if a cooling fan is being tested the engine must reach operating temperature before the computer will trigger the circuit.) The temp increased to to 109C and the radiator fan didn't kick in. Fans should come on immediately at low with A/C switch engaged. If so, a replacement fan costs upwards of $45. The coolant fan will continue to run until the engine temperature cools down to a specific predetermined level. Item number 34 is the Thermo Switch Assembly, part number 37760-MT2-003. A cooling fan module helps to maintain a constant supply of fresh air into the cabin of a car by controlling the blower that supplies the air. 2007 Brute Force 750. 1-24 of 230 Results.
