Hydraulic Fan <= HAA Ford Failure..

[Travis2000LS]

Okay.. so today I thought I would Flush my old Hydraulic fan fluid out completely and run some Seafoam Trans Tune in it because it had looked like somone put water in it.. ( Pinkish creamy color )

So I first drained most of what I could out of the Tank and put the trans tune in and let it run for 30 mins, Watching it put out alot of dang water out of the cap and what not. So Then I emptied it completely again, Spun the Fan by my hand and kept putting more fluid in the line until i started seeing Fresh dark red new Fluid flow through the other line.

Thinking this would surly fix my overheating problem because about 1 week ago I found out that my fan ISNT kicking on to 100% much less looking like its pushing at 30% of its power..

Well No dice.. Flushing the system out didnt help 1 bit..


SO NOW!

What do I do.. What could cause this fan from actuating its speeds??

Worse come to worse.. Would it be cheaper to buy a new fan or whatever, or do an electric conversion..

Thanks again for all yalls help and advice! I do appreciate it.

I read somewhere on someones thread about a relay maybe on the fan ? Might be time to completely change it out and dude they are not cheap i think its about $350 for a new pump and fan.

Im having some overheating issues myself but im waiting for the degas bottle to arrive from rock auto, Did you check the bottle?

Or you might want to just take it to the dealership and have them diagnose the problem, they usually charge around 80 around my way. I feel sometimes its worth it to pay the price instead of pulling your hair out.

Good luck.

I might take it to the dealer :/

Im firguring about 310$

New Degas Bottle, Coolant Equalizer/Bypass Tube, New Thermostat housing, and New Secondary timing chain, and Engine Flush..


Yay..

And it might go up if I take it to dealer and have to buy a new Fan.. or do a conversion..

See why we recommend the gen II?

Man i would try and do an electric conversion.

Assuming you have no physical leaks from the pump, fan motor or hoses, then you need to replace the hydraulic solenoid actuator that takes an electrical signal from the ECU and switches the pump to high flow/high speed for the fan. Sometimes a flush with seafoam will get this solenoid "unstuck", at least on a temporary basis, but in the end the solenoid will require replacement. The solenoid screws into the pump itself and is a bit awkward to get at. They cost around < $100, which is a lot better than a whole new pump.

That's pretty useful! Thanks!

Change to electric

I'm on my 4th hydra fan pump and motor, these things are junk and the cost is out of this world for a dealer repair or anyone else. Think hard about the electric conversion. there are several posts on how to do it. current replacement cost for fan and motor about $1500 or more.

Not usefull info but thanks for the reminder

Thanks im sure this will help other members out.

Pump for sale

I have a Pump from a 2001 V8 that i will sell to you for $90.00 plus shipping. It has the solenoid with it. PM me and we can go from there.

Do the electric conversion, you wont be sorry.

+1 Fantastic advice and this matches my experience. Solenoid is about $80.00 or so from Max if I remember correctly.
