wussup fellas, I have dual fal fans that were on my car when I bought it. for some reason, just today, it started to overheat. popped the hood and the fan isnt turning on. I checked all the fuses and they were good. How do I check to see if it is a bad relay? or fan or switch? I dont know how to hard wire it to see if the fan still works but it has been up until today. The ac fan still comes on when the ac is turned on. I tried to do a search but couldnt find how to hard wire or however you say it to check the fan. Thanks for your help fellas,

Sounds like the coolant temp switch is faulty.

To hardwire the fan, take a run of wire (14g) and put it from the fuse box on an ignition source to splice it into the hot lead on the fan's plug.

any way to check and see if the relay is bad?

jdmturboitr

I want to just check and see if the fan is not messed up. dont want to hard wire it for good.

might need a new fan relay. i would just run two wires into the plug of the fan itself, and then run them to the battery, neg and pos. if the fan works, could be a fuse, relay, or a temp switch.

tried to run it str8 to the batt, fan didnt turn on, switched the plugs to the ac fan, the ac fan only turned on when I switched ac on. it has dual fal fans and the way it has been working is that everytime I turn on the ac, the ac fan would turn on and constantly run until I turned the ac off.....

so....you have a fan burned up is that what you saying?

jdmturboitr

change......... I went to the wires and spliced them to the plug and the fan came on. so the fan works. I guess when I was touching them earlier to the inside of the plug I guess I wasnt gettn good enuf contact. but the fan came on when I spiced into the wires

replace your fan switch on the back of the thermostat housing

jdmturboitr

thanx bro but.............been a little while since ive messed wit my car. where is the thermo housing? under vtec solenoid area right? im about to go start pulin **** off. haha

jdmturboitr

the fan switch the one under the vtec solenoid? mine is green......

jdmturboitr

aight, fan switch changed out, still doesnt turn on. I hardwired it to the batt so that I can drive it to wrk, I get bout half way down the block and she starts overheating again! WTF! fan is constantly runnin and still pegs the needle on Hot. wtflip? any suggestions???????

jdmturboitr

didnt think it made a difference but just so yaw know, she was runnin fine till I changed the oil. used a oil filter from honda and castrol syntec blend. 10W-40.........i usually use 10W-30 but my mom bought me the oil. didnt think it would matter on the weight. thanx again fellas.

start the car and let it idle till the fan comes on , make sure the fan spins the right way.

jdmturboitr

fan doesnt turn on! thats the problem. I have it hard wired to the battery but its still overheating. "spins the right way"? ummmmmm I thought it would only spin one way, how/why would it spin the other way? thanx

gabe

jdmturboitr

k, made sure its spinning the right way, still overheats when I take off. its fine at a idle. as soon as I get into like 2nd gear drivin down the road she shoots to hot.....earlier it looked like the needle on the temp gauge was going up and down then it would shoot to "H".......im puzzled and a little frustrated.

follie gatts

sounds like the fan isn't the problem. have you ever changed the thermostat?

jdmturboitr

naw, I havent changed it since Ive had the car. go n on 5 years, its markin about 193k.......but does that have anything to do with the fan not turning on when it gets hot?

follie gatts

if the thermostat isn't opening to let coolant into the motor, it doesn't matter what your fan is doing to the coolant in the radiator.

i am pasting from my service manual, pardon the weirdness...

Fan Motor Test
Disconnectth e 2Pc onnectofrr om the fan motor.
Test the motor by connectingb atteryp owert o the
B terminal, and ground to the A termlnal.
lf the fan motor fails to run smoothly, replace it.
NOTE: The illustrations hows the radiatorf an.

if you look into the connector with the notch facing towards the sky, the A terminal is on the left.

the fan is supposed to kick on at 196 degrees F, or rather the fan switch delivers juice to the fan. the switch could be bad, or the thermostat could be bad.

follie gatts

the fan switch test says hang the fan switch in coolant and add a thermometer. heat the coolant and make sure the switch closes (passes juice) at 196 degrees F

jdmturboitr

ok. there sems to not be a problem with the fan. I hard wire it to the battery and it comes on. so the thermostat would keep it from comin on?

jdmturboitr

what is the OEM temp? autozone has 3 different thermostats with different temperature settings. one for 170 deg, 180 deg, and 195 deg.........the 170 deg one is only 13bux and the 180 is 8bux 195 deg has to be special ordered

follie gatts

no, the radiator fan switch turns the fan on. the thermostat is a mechanism that lets coolant into the engine block.

the integra thermostat is a 170 degree unit.

aight, first off, let me just say "thank you" to all da fellas who helped me. I finally got it straight. Turns out that I had some loose wires on the plugs to the fans(figured that out with a voltmeter) then figured out the fan switch was bad. took out the thermostat and tested that since I was there, thermostat was bad, stuck closed. replaced that, she runs like a champ...........THANKS again to everyone who helped.
