Two things. No need to remove the lower radiator bolts, just loosen them enough to slide the fan frame out. No need to start the engine, just turn key to run position when A/C is switched ON and blower motor is switched ON. Nice video overall : )

Thank you for this video. I bought a 2007 CRV in India and my mechanic did a coolant flush. Since then the car is overheating when I a/c is turned on. I noticed 1 fan wasn’t working also. Therefore it could be the fan.

Great video! I had the same problem with the wire on the air conditioning fan I replaced on my 98. The frame simply didn't work. I had to take the new motor out of the new frame and put it in the old frame. It's an easy change over. Just a small detail: you don't have to take out the bottom bolts. The frame is slotted where the bottom bolts go in, so you just have to loosen the bottom bolts and take out the top ones. All the best, Cheers Rick

In my case its the PFI Sub Relay or (ECU) not energizing the fan relays.

Any thoughts if neither fan kicks on? We have a 2004 with same issue. Fuses are good

@FamilyFriendlyDIY Ай бұрын

Check all of the wiring to the fan motors and grounds. You could test the fans to see if the motors work by getting some wire and conecting them directly to battery voltage. Also test the temperature control switch.

My 97 Honda CRV is overheating. The fans don’t come on when the AC is off but they do come on when the AC is on. I have replaced the coolant temp sensor, the radiator fan, the coolant hoses and nothing. What am I missing? Thank you.

@FamilyFriendlyDIY 10 ай бұрын

Your thermostat might be stuck closed not allowing the hot coolant to make it to the sensor to heat it up ... check out this link for more info honda-tech.com/forums/acura-integra-6/coolant-fan-only-wants-work-when-ac-3063081/

Try bypass the fan temp switch (supposed to switch ON fan, at 93C), by shorting its connector.

@FamilyFriendlyDIY Жыл бұрын

That's a tough one. It sounds like everything is new. Have you tested the engine coolant temperature sensor? It may be causing the gauge to read hot when it's really not. If the engine really is running hot, my only other guess would be there is a clog somewhere, or a buildup of scale that is impeding coolant flow. Has the "overheating" been getting worse gradually? or was it a sudden change?

@mclovinpo Жыл бұрын

Both fans went on then the engine one went off, is it the fan that’s the problem? Since power went in

Does the engine fan come back on as the temperature rises?

@@mclovinpo my guess would be something wrong with the engine coolant temperature sensor- which you can test … but if it has caused a coolant leak somewhere, that’s usually not good. Usually means something has been warped… like the head gasket.

After reading your comment, Pedro, I checked the oil. Looks like it's burned only half a quart in the last 330 miles. I've got to say it's been really reliable, and I think it rides better, accelerates smoother, and has more power than the Honda Fit we just bought. I prefer driving it over the Fit. I've been getting lots of good suggestions from viewers, and I hope to produce more informative videos soon. Thanks for the comment!

@FamilyFriendlyDIY Жыл бұрын

Are both fans actually running? If so, it might just be your thermostat isn’t fully opening. If you haven’t already, I would start by changing that.

@@wisetv9132 Since it is only while sitting still and not driving, it is probably fan related. Do both fans come on when you turn the AC on? Both fans should instantly come on when you turn the AC on.
