Ford Transit Cooling Fan Diagnostic. FANS NOT WORKING OVERHEATING!!! (FIXED)
Вставка
- Опубліковано 4 січ 2023
- If your engine is running hot, there are a few potential culprits. First, check the coolant. Make sure the coolant is full and the mixture is correct. Next, check for any leaks in the radiator and cooling system. Any leaks will cause your engine to run hotter than usual. Finally, make sure that the fan is working correctly and that the fan belt if you do not have electric fans is in good condition.
If all of these things check out, then it may be time to take a look at the thermostat. The thermostat could be stuck open or closed and this would cause the engine to run hotter than normal.
In this video it was the electric cooling fan circuit that was faulty. Follow along as we trace through the circuit and test to determine which component is defective.
The electrical diagnostic process was challenging But with the right knowledge and tools, it's possible to work through the process and find a solution. I'm glad I was able to work through it and find a successful outcome. #ford #transition

the process of elimanation you're doing is incredible
Somehow I find myself loving these types of videos. In the moment of electrical issue troubleshooting I am cursing myself for getting into such a mess, but fixing the issue is so gratifying. Thanks for the rundown!
You are so correct
Man! Wish I would had seen this video a week ago, it would had saved a blown gasket. Great educational video, thanks
Have to share this breddah, up!
Please do. Respect
Excellent, you really deserve 5 🌟 stars.
I had this issue with my Transit. Your video walkthrough solved my problem. A million thanks.
So happy to hear that
I am studying electromechanics and heavy equipment technician here in Panama, i always try to see all your videos, bro you are great, you inspire me to continue with my carrier, thanks for share your experience!!! blesss Yaaahhhhh
Lol you will be awesome I am certain. Just pay attention and get as much experience as you can even for free. The knowledge is what you are after. Then you can charge the big bucks
Great diag and will keep this in mind!
Excellent breakdown of the troubleshooting process. Thank you.
Respect teacher I'm learning a lot of stuff frm ur videos
That's a perfect explanation, I'm going back to school. Thanks again
Love your videos and Blessed day to you sir
Thanks man very informative 👍
That was awesome
So informative and such a treat to watch. The way that you broke down the relay system and how it works in relations to the fans was really impressive and expertly done. I really enjoyed this and I would love to watch more of your stuff
you are so very welcome. My subscribers get notifications. Please consider subscribing
Nice and thorough approach, loved it. I however would go further test and change every fuse & relay which relates to those fans to ensure everything proper.
Very nice detailed diagnostic,thank you.
You are welcome
Nice job 👍
Thank you very much for your video. I have a Parts van it was doing exactly the same thing. Saw your test plan checked it blown fuse. Thank you again very much for that.
Glad it helped
Perfectly expained 💥💥 thank you rust man
Thx I brush the Rust off
You de best mate
Awesome diagnostic
Thank you
You know your stuff man . Great work
Thank u
Excellent work, thank you!
Thank you too!
You did a great job I
Thanks
Thanks for the teaching process
U welcome
Blessings for sharing!
Welcome
Blessed man
You’re star 👍🏻
Thankful
bad you bad🔥
good job!!
Thx
gracias maestro
Welcome
I told u teacher! D class filling up fast iyah. 🇯🇲
Good troubleshooting walk thru 👍...those fuses seem horrible to work with
Thanks awesome video. I had the same problem. All three cooling fan fuses were blown. Any idea if this is a common electrical issue?
Thanks for the video.
Great job but what was or did cause the fuse to be blown in the first place, a bad ground??
love your videos Rasta. but this one did not make sense to me. why when you swapped the relays they stoped working? that tells me that one of the relays is no good. second while looking at the video again i see that when you swapped the relays that blue fuse was already missing. can you clarify that for me?
You did better than I could have done. I would have walked dung dis rabbit hole different. Would have chased why the gauge reading normal and the MaxSys reading 224F. Would have sed to myself the temp sensor is in a gas bubble caused by head gasket gases… and just changed the head gasket, skim block and head and probably overhauled the engine. I would have been WRONG…
Lol it happens it happens. I was authorized to do a head gasket job
The reason for the three relays and the extra fuse, is that the AC turns on the low speed on its own.
This is basically the same system that GM uses on some of their vehicles as well now with the same three relays setup, however as far as I know GM is detecting whether or not the fans are running with some current sensing in some cases and so the BCM can tell when the fans are not running in low speed and can force it in to high speed even before the temperature gets too hot.
It can also detect a failed fan sometimes, and then force the working fan to high speed to try and compensate.
Ok nice thanks
big up
Respect
Awesome explanation! Where are you based can I bring my car to you?
I notice that if I turn on ac or windows defrost the high speed fan runs and run after I turn of ac or defrost I will only turn of after I turn van of for about 20mins
Where there any codes that popped up for this issue?
Wag1 G,
My Ford Transit 2.0 EcoBlue Diesel (UK Version), when I turn the AC on, the high speed fan kicks in intervals, and this never use to happen before. I use to hear the low speed fans, however, for the last 2 weeks the high speed fans keep on coming on each time I turn the AC on, what can be the symptoms of this problems ?
Thank you big man
Bad low speed fan relay or low speed fan fuse
So i have a 2007 Chevy Cobalt 2.2L LT. The high speed fan runs constant and the car wont get up to operating temp.
I changed the temp sensor, thermostat water pump & coolant reservoir cap. I pulled relays and low speed works as well as high speed.
Temp sensor only reads wen CEL is erased, fans not on wen temp sensor is reading.
Car wont pass 150 degrees, then CEL comes back on (P0128) now high speed fan is on constantly again.
What do i check now? Please help
Email me at rastamanbuilds gee mail and I will share what I know and see if it helps.
I have a transit mk7 with the same problem won’t blow hot air changed thermostat still not really heating up help me bro 🏴
Check the temp of inlet and outlet heater core tubes then email me at rastamanbuilds gee mail. If the temps are low then its not the heater core
Where can we print out those diagrams??
Its a paid subscription with Alldata
Learn smthn today. . Man them a JAGAS nuh teach them simple smthn yaah lol
Where can I get the wiring diagram from?
Email me at rastamanbuilds gee mail
What if all my fuses and relays are good and pcm grounds fine. I have brand new fans from ford and still no fan operation ……Help!!!!!!!!!
Then the wire from ecu to relay must be checked for continuity
Always check the voltage at fan pwr connector as well. Theses fans are wired in series for low speed and parallel in high speed. also check for GND continuity. The GND It is a double wired (one for each fan) blue with black stripe.
I like your contents. I am in that field. How can I contact you?
Thank you. Shoot me a email rastamanbuilds@gmail
RITE DEAR
Lol hahahaha thats what I said
First, it is a Ford of all things. If it was my car, I would just provided a normal ground.
You bad
It was tricky lol
