Auxiliary Fan/AC Condenser Fan Motor

[Arnival]

I just changed out by auxiliary fan motor using a Denso fan motor from a 1993 Toyota Corolla. Thanks, jhelton001, you saved me $$$$. The fan motor on the passenger side went out. I didn't realize it was out until I was on my way to Pismo on a 105 degree day and I started to overheat. After changing it out I noticed that the Corolla Denso motor was blowing harder than the good LR Denso motor. It was back to the junkyard to find another motor. The Toyota Denso motor turns a 12 inch fan versus a 10 inch fan on the disco. I think this is why it blows harder. You have to get the motors from the junkyard. Kragens, Autozone, Pep Boys will sell you an aftermarket 10 inch fan with shroud like Flex-a-lite, or some other cheap piece of crap. The holes don't line up and and you would have use those cheap zip ties. The Toyota Denso motor is the same size as the LR motor and fits perfectly. BTW, I paid $45 and $25 for the motors. Hope this helps.

i wish i knew that when i paid an arm and a leg for those things. did that fix the overheating? just wondering becuase i never overheated without them

I think I overheated because I was running my AC with my truck fully loaded and a rooftop carrier on a 105 degree day. My temp would go down when I turned the AC off. From the RAVE cd:

The Condenser Fans Motors (M113, M121) on
vehicles equipped with MFI?V8 engines operate
when any of the following conditions occur:
8. Coolant temperature exceeds 100
C (212
F).
9. The air conditioning system is operating.
10. The Engine Control Module (ECM) (Z132)
determines that fuel temperature exceeds
70
C and coolant temperature exceeds 110
C
after engine shutdown. When this occurs, the
fans are turned on for approximately 10 minutes
after the engine is shut off.

Yup, for the first time ever, in 108 deg, the fan came on after i turned off the truck. The hood temp with a IR thermometer was 187, so i'm sure it was more than toasty under there!

It is a cool swap, I'm happy you saved some cash.

 

[Arnival]

jhelton001, do you know of any other cool swaps. How did you ever find this one.

 

[jhelton001]

lots of looking at bs on e-bay, found what looked like it would work then hit the junkyard. That is the only one I know of but Discoweb holds many things like this. Search the GM fuel pump one that is a money saver also.

Mine are toast also on my 97 Disco.
So last night, had two hours to kill, so I thought I would just remove the offending fans and replace the motors once I found some out of a Corolla.
Tore into the front, took out the 4 bolts on the first fan and that #$%@#% connector was on top of the condenser and it was not coming out the front!!!

Did anyone up in Virginia hear my slew of vulgarity that was coming from my garage in Tampa????

Yea, I had to slap it back together since I did not have the time to unhook the radiator and get to these damn condenser fan connectors.

I called a buddy, James at British 4x4 in Jacksonville and he made me feel even dumber. He told me that the plastic sill under the condenser can be dropped and the fans can be dropped through the opening as opposed to dismantling your front grill, cross bars, tranny cooler moved…

But still, in order to get to the connectors for these fans, you have to loosen and tilt the radiator to get access to the connectors.

Thought I would share that tip for the next person who is about to tackle the condenser fan DYI route.

Later.

I just cut the wires.

Good choice as well since I doubt the new motor connectors will match the LR connectors.

They don't. I just got one in today. Toyota 88150-12130, list price of $120. It fits a GS300 and some Corolla. I did a search and found aftermarket here: http://bbb-carb.com/hc/Toyota.htm I cannot vouch for the aftermarket, but the Lexus/Toyota part fits like a glove with the exception of the plug. I ordered 5 more today. Someone should order the aftermarket and see how it fits. Nicely done on whomever figured this one out. $240 for a pair of fans beats $900 any day. We have a lot of older trucks out there with dead fans.

 

[Arnival]

Aftermarket will not fit, as it is a whole assembly with different size motor and shroud. Tried this already.

Wow, $120/motor? Hope these were 'NEW' motors. I just paid $75 for two.
