Any interest in an auxiliary AC condenser fan kit? INSTALL DIRECTIONS IN FIRST POST (2 Viewers)

And why would i want my wife to ride in my 80? That's crazy talk!

Well, I mean... someone's gotta push...

OK, fellas... I've got two boxed up and ready to go. $215, shipped in the lower 48.

Is the fan manual on/off switch or temp sensor activated?

Is the fan manual on/off switch or temp sensor activated?

It's wired on with the ignition, so key on = fan on. There's a temp sensor in the harness that will shut the fan off if it's below 60°F ambient. If you need to shut it off manually, there's a fuse on the relay that can be pulled.

*edit- I'll be posting install directions with pictures tomorrow.

I have zero experience with the LCP kit, but it uses what looks to be the same fan as my Sequoia and the fan I'm using on my 80 moves a LOT more air than that fan in the Sequoia. Let me finish mine up and crunch the numbers, get a supporting vender status, then we can talk prices and whatnot.

*edit- I too replaced all my AC components, so I essentially have a new AC system (plus a modded blue fan clutch) that this electric fan is making an improvement on.

Nice to see a new product..

FWIW the fan we used was from an early 100 series.

The only reason we stopped was that we could not get DEPO to produce enough. We would run out every year.

Thanks, Phil! Your supply chain issues is one of the reasons I went with an aftermarket fan. That said, I had a hell of a time finding a place that would reliably ship the correct fan. I think I returned five or six fans throughout the process because they weren't what was pictured, didn't have the correct blade design, or would have required a complete redo of the mounts.

Even thoughts AC is off, the fan will kick in if anbient sensor sees 61°F?

Yes. These were the only sensors available at the time. Future harnesses will have the off temp set at 77°F. Alternately, there's a fuse on the relay that can be pulled if you want/need it off. I decided to not use a switch on the dash because 1) I wanted to keep the install as simple as possible, and 2) I couldn't find one that was labeled "FAN" and that looked OEM.

A way is to wire it to the A/C trinary pressure switch, using the unused middle pressure pin as a ground to activate a relay to turn the aux fan on. There is a write up on it.

 

[Mandrake]

I considered that, but it's my understanding that it turns on and off, and if triggering the relay, would cause the fan to turn off when the compressor is off and only run when the compressor does. The condenser still has heat to shed even when the compressor isn't running and I wanted the fan to run continuously so that it could help the condenser recover more between thermal loads.

 

[Mandrake]

OK, both fans sold and both headed to TN! Looks like I'll have to bend up some more metal and cut up some more wire. Thanks for the business, guys! It really means a lot to me.

 

[NeverFinis]

No, it should have nothing to do when/if the compressor is running. Only depends on A/C pressure:

MED pressure circuit - on - continuity = 192psi (Aux Fan on)
MED pressure circuit - off - no continuity = 156psi (Aux Fan off)

Part III - Pressure Switch Activation of Aux Fan for better A/C Condenser Cooling.

In Part II, you will find the relay trigger options for wiring the pusher Aux fan for maximizing A/C condenser efficiency. In Part III, I will detail the procedure for wiring the Aux Fan to come on using the A/C Condenser Pressure switch. Luckily for the Toyota purists this uses only 10 dollars worth of Toyota Parts.

By now, you should have the Aux pusher Fan mounted in front of the A/C condenser, a relay mounted, and your Battery Feed (with appropriate Fan Fuse please!) to pin 30, and the Fan...

I like how that keeps all the wiring in one area without the need to run the relay trigger wire into the cabin. I'm going to look into that more. Thanks!

Smart guy here .... I just dove down this wiring hole on a ls swap i finished 2 months ago. Smart guy im referring to you @NeverFinis

I've updated the first post with install instructions. If you have any questions about it, post it up or PM me.
