radiator fan running high
Is the engine hot? If so the fan is doing its job.
no, the temperature is normal
The fans should come on at preset temperature and then cycle off once the fans cool things down a bit. Are the fans coming on and off or do they stay on all the time?
only 50,000 miles on it. also the heater is blowing cold air.
the fan gets loud after about 15 minutes of driving. it has never done this before.
If you have a clutch fan the clutch is probably bad. The heater problem may be a bad thermostat or air in the system.
both symtoms seemed to be linked because they began at the same time.
If the engine is running hot the fan will come on more. Maybe you should service the cooling system.
Is the fan electric? If so it could be a defective pressure switch on the AC compressor.
I have a f- 150 2013. Both cooling fans run all the time after 160 degrees. They changed the water pump. Then the shit started. Before that they never kicked on
I have the same issue. I HAVE to turn my car off to go through drivethrus. Its embarassingly loud, my wife says she can hear me coming. Father in law even commented on it. Didn't do this in the beginning but now that fan runs so hard. Took it to the dealership. They say some wire on the fan burnt out.
I have the same issue as well. I have a 2012 Ford F150 Fx4. There is a fan noise coming from my engine compartment that is really loud. The fan kicks on and off. Also when I am stopped or moving really slow my truck is blowing cold air even though I have the theromstat set on heat. Spectrum_7968 did you ever figure out what was wrong with your truck?
Sams issue. 2013 fx4. Fan running fast and when the heat is on cold air. Started yesterday. Any answers?
I think we have narrowed it down to a coolant leak but we haven’t taken it to the shop to find the leak yet. But we are having to add coolant every week to the truck.
have been having the same problem with 2011 F-150 Platinum. Mechanic said coolant was low. topped off and reset the system. So far so good. Did not identify any leak but will have to keep an eye on it.
I have 2012 F150 XLT just had the same problem start happening. Heater will not blow hot air unless I rev up to 3000 RPM or so at stop light. Goes back to blowing cold air when going in 30-40 MPH traffic. Some loud auxiliary fan is coming on. Will have to check coolant and system. Thanks. I will get back here about this.
Humm Yea added 1 3/4 gallons of 50/50 antifreeze into the plastic coolant reservoir. Heater works, did not hear the loud auxiliary fan on the way to work. BTW I am found out in old school again. The only way to add water/antifreeze now is through the plastic coolant reservoir? OK I guess. Now to find the leak.
I’ve got a 2012 FX4 5.0, with a performance Tune, but the last few days I’ve noticed my coolant temp getting in the 230° range and a fan kicking on. Then today while driving home the temps reached up to 240°, going in tomorrow to get the coolant system check. Hopefully it solves the problem.
Exact thing happening with my 2013 150. Fan kicks on, won’t blow hot when stopped or driving at a low speed. Anyone have a solid answer?
I changed my thermostat and about a week later the cooling fan started coming on intermittently at high speed. This is in 0 deg weather. One post talked about resetting the system. More about that please.
I am having the same issue, the cooling fan comes on and stays on at high speed. I took it to the dealership and had it serviced and they said it was coming on because I was running the defrost. The temperature has been In the 20s all week, but now is a Saturday and it is 70° outside and now my AC does not blow cold air. Any ideas?
The AC High Pressure Switch (Behind RF Headlight On A 2013 F150 Towards Middle)Could Be Bad. Have To Monitor It With A Scanner. Pressure Shot Up To 425psi, when AC Was Shut Off Pressure Would Drop Real Slow, So Fan Would Stay On High Unless You Switched It Off. Ours Was Actually .5 lb. Low Charge. Compressor Is A Little Noisy & Ford Appears To Be Using Expansion Valve Instead Of A Tube. This Thing Seemed To Straighten Up With Just A Charge. So I Guess We Will See!!
@TheJamster1 Have you had any problems since the charge?
I have the problem with my 2013 f150 unhooked the ac switch and fan stoped have check Freon level next hope its a easy fix.
Mine is in the shop now with over 300psi and they don't know why... and my cooling fan runs pretty much all the time. Mines also a 2013 F150
I still have the issue. When I get home I can bleed off the pressure and air from the reservoir. It helps for a while but the fans start kicking on again after a day or 2. I see a lot of posts describing similar issues but never any fixes. Has anyone tracked this down?
They said mine was .7lbs low and recharged mine and it has been fine since Thursday. I did have a coolant leak but got it fixed, i thought that was why my fan was running. Fan still ran so it brought it back in the shop... they are baffeled and don't know why or how the pressure got so high sitting still and with the A/C off
Having the same problem with my 2011 Expedition. Fan starts going on and off, very loud after driving about 10 minutes. Heater blows cold when driving very slow or stopped. Did anyone figure out what the problem is? Please help.
I've heard its because of a coolant or freon leak!
