How To Automatically Control Your Jeep Xj E-Fan On A Budget And With Ease!

[@Steve_Reject]

For my XJ I put in a time delay relay so I flip that switch on and it stays on until I turn it off. When I turn the switch off, the time delay activates and keeps my fan running for one minute whether the engine is on or off. Works great!

[@davidmoore_oo1]

Good work. I appreciate the content and fun commentary. One thing to help others - that "aluminum" wire to the temperature "probe" is actually a tube that carries pressurized alcohol, so you CAN'T cut it OR kink it. If you do, then you just wasted the controller, because itll never work again. I find it best to leave most of the aluminum tube coiled up as it was in the box, and only unwind what is needed to get to the radiator. And i like how you just mount the "sensor" end inside the top hose protective shrouding. Extra points for use of Duck Tape. I've replaced the burned diode pack that is factory hard wired into my '90 xj a few times.

im loving these videos man. its keeping my old jeeper runnin good (shes all i got *crying face*)

[@DannyCsaszar]

Great video, I have been enjoying my setup like this for a long time. I wire tied the probe to the hose too. I did a relay and kept the oem connection but through the relay so when the thermostat switch triggered it closed the relay to enable the thermostat.

Finally got the glue tread repair kit I’ve been yapping about 👌🏻

[@dexjs]

Is it in the video?!?

[@Dmowery5036]

Another very helpful video!! 👍🏻👍🏻

[@sheepwolf1st]

More than one way to skin a critter... really great info, thank you.

[@mrkultra1655]

Thanks, that's a good set up

[@WylieWiggins]

Nice, and likely cheaper than a W1209 temperature control circuit board, a water tight project box and a relay fused with a few add-a-fuses. I've never done this, it just came to mind watching your video.

[@chadsanders3506]

I used the same switch dex is using, but I used for a ground for a switched ground relay,

[@M_Phipps0520]

Good information!

[@slantedperspective]

Look into thermal switches. Cant remember the name exactly but it screws into the bleed thrn run it to a relay and it pops on at whatever temp you get. Very similar consept!

[@ericsennert7933]

Dex, you hack job buddy will love this.

[@destinyballard925]

Jeep stopped threatening you? You wearing your logo again!

[@dexjs]

Ain’t scared. I got yalls support. 😜

[@Jfreeman-k4l]

I’ve used a hot water thermostat to turn a fans negative on and off the top hose.

[@TheDylon121]

Hey dex something I haven’t seen yet on KZbin or good information online is the difference in Dana 30 axles that come underneath Cherokees. Iv swapped out a set that had 373 gears and went to change the brake calipers and they were very different from what was originally on my 98 wasn’t to sure if I could take the bracket off and “update “ them or if I’m kinda stuck with what it is. Anyways just a video idea. I would of thought they were all the same but guess they are not

[@craigdoesstuff5270]

in the future it would be helpful if you put the links to the items in the description

[@Lachen908]

I have mine hooked up to a relay, circuit breaker, battery, then finally the switched 12v to my radio so it comes on with ignition

[@savage22bolt32]

When I replaced my XJ 4.0 radiator, I didn't reinstall the electric fan or shroud. It always runs at 210° on the temp gauge. If you have a leaking heater core, check out how I fixed it on my yt channel. It's still working for a few years now!

[@jeremyhanna3852]

On the older cherokee the flat plug is a delphi weather pak 2 pin connector easy to get And you said you didnt know that fan controller works that pill part has a mecury like substance in it and when it gets hot it expands back up the tube and completes a circuit in the controller

[@mmadrid295]

Will you do a video on the volt gauge dropping

[@dexjs]

That’s on my list too!!

[@Racerflea]

If the Cherokee has issues running hot wouldn’t removing the thermostat, therefore allowing constant flow through the radiator, help alleviate the issue?

[@JBdizzy]

You have any videos of working on a jeep compass 2.0 motor?

[@dexjs]

I don’t. Sorry

[@jamesdodson9417]

What is the lifter creeking after you turn engine off on a Cherokee ? Might make for a good video…..

[@CGRFS]

Lifter bleed down

[@VC-TV]

Hey Dex! I just did engine mounts today! Give us some tips to make it easier please! Idk if you did already, i found it to be a pain in the butt, driver side was easy and lifts up, passenger side not nearly as high, and passenger side is the pain in the butt side!

[@VC-TV]

Center bolt a pain to line up on passenger side but i got it couple taps of the hammer and lifting engine way higher than i wanted to, wasn’t impossible but definitely a sketchy process

[@lookoutmountaingarockhunte1300]

LOVE IT 😊

[@noberet]

2:10 "like a spring and something that gets hot and clicks over" sounds suspiciously like a relay.

[@hoslerwhitney3574]

Have you ever had an issue with your Cherokees repeatedly having their blinker and blower relays go bad?

[@jeremyhanna3852]

Check your windshield gasket in the vin number area it leaks and the under dash gers wet

That's way I been doing for years works great parts store does sells them if they know where to look universal fans aftermarket to kits are usually two of them this metal with probe other is way more sophisticated not worth it lol . Patch into relay for more amp setups etc

[@SuperUnknown1967]

Good one Dex!

[@eddiereichel9354]

10 years ago I had a trailblazer that I put a lift and 32 on. It got shitty mileage. The Internet told me to take mechanical fan off and use a electric fan. I forgot to turn it on and smoked the engine. If only I had 20 bucks and watched this video ....

[@nathanhyland910]

So, my XJ’s (2000)fan does come on auto, is there a year gap where they don’t? Or do some just break?

[@Fooses]

00-01 fan only comes on at 218 and shuts off when it cold to 208.

[@Fooses]

Sorry misread. But I have 00 too and it only briefly comes on at the temps described. Much more peace of mind to just switch the fan on and leave it when crawling on a hot day

[@nathanhyland910]

@@Fooses yeah that would be nice, I tend to just do the “overland” BS and occasional mud run stuff, I’m over in NC not may rocks to crawl

[@Fooses]

@@nathanhyland910 same here. By crawling I mean going slow in 4LO uphill, everything working hard and no airflow. Flip the fan on and the temp needle stays a good half tick left of 210 the whole time.

[@kevinstott1317]

Maybe a dumb question but this is for when the factory fan control isn't working right?

[@papatomsthoughts]

That is my guess. 😊😊

[@DannyCsaszar]

It's never working right in my opinion since it triggers at 220 and that is way too high.

[@KCsRefurbs]

Yes or make adjustable but run lower temps which these run to hit cause other problems. Plus motors get hotter when you shut them off etc if wires like this it run for like 10 minutes when you shut it off to avoid this problem just make sure battery good and not weak reserve capacity etc

[@kevinstott1317]

That's a bummer. Mine kicks on at 210 or with high pressure on AC. But I've also noticed it creep up after turning off like he mentioned. Either way glad there are videos like this that keep me learning

[@aaronyates6753]

Unhook ac compressor, then bypass low pressure switch for ac. It all works from climate control. Just turn ac on

[@brysonshires9742]

That's how I have my Mazda set up. Helps heat soak a tonn

[@CGRFS]

What happends when you forget to turn on ac??

[@mattlinderkamp9489]

My daughters 98 is always cycling on/off, drives me crazy, is that normal?

[@savage22bolt32]

Must mean it's working

[@kevinstott1317]

If it does it when ac is on it could be the compressor is short cycling on and off triggering the electric fan. Usually means it's low on Freon.

[@Bodie2020]

We just unplug the sensor and it stays on while we are at the trails.
