I used this video today to diagnose and fix my daughter’s CRV with this EXACT same problem! Video was so informative, and walked me through the process step-by-step. I am a 43 year old woman with no car repair experience. For real, this was my first repair, but my husband isn’t in town and the car was overheating. With bated breath I started the car and turned on the ac, the absolute delight I felt when the new fan started spinning was amazing! Thanks for putting out content to help us regular people, Dave!!!
For the last 3 days I've been preforming major surgery on my 2000 CRV. It's a fun project and I think my odometer is at 227k too. Thanks for the video.
@@FamilyFriendlyDIY Hi Dave, I changed the cam seals, belts, water pump, tensioner, timing belt, and broke a bolt along the way 😂 I still have to change the valve seals because my vehicle smokes after extended idling. I'm not a mechanic so this is all new to me but is a lot of fun.
@@mybrotherscout3661 Glad to see that you can stay positive while doing the timing components. It’s so tight in there! You’ve really accomplished something when you get that done.!!!
11:03 - "let's test it to make sure it works" BEFORE installing into the vehicle. I don't know how many times I have installed parts without testing them - assuming they should work. +10 man points.
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
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 : )
I change both heating sensors.change both relay checked 20 fuse and termostat and still the fans don’t turn on when reaching 200 f temperature. But when i turn AC on they both turn on.
What do you think the issue would be if the radiator fan only comes on when the AC is turned on, but will not come on when the vehicle tries to overheat? The coolant temp sensor on the thermostat has been replaced and has continuity when it should.
Hmmm. The only other thing I can think of if those two things are true is that might a problem with the computer. I hope it’s not. Maybe someone else out there has an idea?
@FamilyFriendlyDIY it may very well be the computer. I have an issue with the security system on mine that I haven't been able to resolve, which I'm sure is computer related.
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.
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/
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!
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.
@@FamilyFriendlyDIY I do think so, as it overheated I didn’t check last night, should I wait for it to overheat ? Think the overheating cause a leak in coolant or something too
@@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.
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?
@@FamilyFriendlyDIY ok i got the part and one gallon of coolent i called a mechanic hes like is not the thermostat bring in so i could see it . The problem is when iam idle with the ac on it over hears only when is realy hot out . If iam driving with the ac no matter the temperature its fine it wont heat up . I changed the fans and the water so it has to be the thermostat right
@@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.
@@FamilyFriendlyDIY fans they do come on and i have replaced both recently so it couldn’t be the fans . When its 96 degrees out and iam just idling with the ac on the its starts overheatingafter a good 8 min . Once i start driving with the ac on temperature goes down

😅😊clear and Easy...from Argentina..IAM 72 and is expensive switch don't sale...but I try to keep my 2000 in good service
All the best to you!
How long does fans stay on with AC off? How many seconds do fans on before turns off? Thanks
Use only genuine Type 2 coolant for the CR-V. Mine is going on 247k miles. Good video!
Thanks for the advice!
In my case its the PFI Sub Relay or (ECU) not energizing the fan relays.
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 : )
Thanks for the tips!
Does it matter if the heat is turned up all the way?
@@mikewilliams4947 Does what matter?
Thank you had same problem i managed to diagonise the problem thru your video
Glad it helped :-)
I change both heating sensors.change both relay checked 20 fuse and termostat and still the fans don’t turn on when reaching 200 f temperature. But when i turn AC on they both turn on.
Hmm. The only other thing I could think of is the ECU. But I wouldn’t even think it was that.🤔
Did you figure this out? I'm having the same exact issue. I'm about to change the water pump as my assumption is the coolant isn't circulating.
Dad to the rescue!
Cheap dad to the rescue ;-)

22 mm for temp switch I think. ?
God bless
:-)
What part number is the fan that you bought?
It’s your fan same problem with mine change thermostat and fan!!
Definitely was the fan.

Try bypass the fan temp switch (supposed to switch ON fan, at 93C), by shorting its connector.
How’s the Toyota doing any updates

Any thoughts if neither fan kicks on? We have a 2004 with same issue. Fuses are good
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.
We will try that, thank you for taking the time to respond!
@@msiebs5040 it might be called the ECT sensor or switch, for “engine coolant temperature”
1:02,sir, what this mean that this could be reversed, Please explain and clear my doubt
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?

Hi Dave, What scanner did you use for Honda diagnose?
I use a Bluedriver. ... I don't remember if I used it in this video though?🤔
@@FamilyFriendlyDIY Lol, You have not use any scanner in video. I want to know if you have time to test our Launch Honda scanner
I have a Honda CRV 2000 and I remplace the radiator, thermostat, fans , everything looks like is working fine but still overheating, please help 🙏🏻🙏🏻

I have a 2007 honda crv i changed both fans and it only gets got when i turn on the ac
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.

No need to drain the fluid, that's the UPPER radiator hose😂
It's still full of coolant if the radiator is full. Why would you want to get antifreeze all over if you didn't have to? SMDH
When you started car that fan kicked! Yikes
Lets hope the other fan does not have 200,000 mi on it.
Hmmm.... uh oh ;-)
