Looking for suggestions. A few weeks back my car over heated and steamed over. I went and checked the fuses and the 50amp under the hood was blown. Replaced the fuse and went to top off the coolant and noticed the fan was still not kicking on. Tried both heat all the way on and getting the car to operating temp and also tried turning the AC on and still no fan. Are these fans prone to fail? is there a relay or something I don't know about? Any suggestions what to double check.

Yes they are. Theres a chance the fan broke and is jamming the motor. There's a thread on here somewhere with the Dorman part number.

My fan took a dump. Caught it before it really shattered and made a mess. I swapped an old Mark8 fan I had laying around from my fox body days. Fits like a glove and in my opinion moves a significant higher amount of air. Mark 8 fan has 7 blades and supposed to run at higher rpms than the new edge v8 fan. I figure the extra blades help out. .

It’s not a bolt on affair. But it’s an easy swap. I tied the 2 positive leads from the CCRM together was the mark 8 fan motor is a single speed. it does have 3 wires but two of them are positive.

i figured a OEM fan would be more durable than a Dorman.

BTW Ford does still have supplies of OEM fans. I’d rather spend a few more bucks versus Dorman.

Unplug the connection on the fan and run +12v and ground to the connector to test the fan.

Three wires total, one is high speed, one is low speed, and the last is ground. That’s the easiest way to test if the fan motor and/or the low speed resistor is good or bad.

Quickest easiest is to unplug the fan and jumper it to the battery. If it comes on jumpering it than you know it's plug back but if the fan does not come on then you know the fan is most likely dead. Could be the CCRM or could be a fuse or other.

I had an issue on connection at fan

fan side, barrels were back to far and had intermittent contact,,

the Dorman fan side by side to ford

exactly the same thing right down to casting numbers on plastic

there is also a resistor on fan case

green barrel looking thing ..
this will also cause some problems

keep the old one,,fan comes with a new one
