Advisory: Failing Radiator Fans in Jeep JKs

My Jeep had been sitting in the garage for maybe a week.  So I decided to start it up one day, and was greeted with a new chime, and the dreaded Check Engine Light.

I ran my diagnostics through the Bully Dog, and the result was surprising – it returned codes for P0113 – Intake Air Temperature Sensor Circuit High, and P0480 – Fan 1 Control Circuit.

I forced the fan on via the Bully Dog, and nada.  As a friend of mine recently replaced his fan assembly, I figured I was also looking at a $120 bill and 10 minutes of work.  Well I was wrong.  He has the 3.8l.  The new fan (OEM replacement) is a whopping $500 and very hard to find in stock.

With my wedding approaching (and the Jeep playing a key role in it) I was desperate to find out what was happening.

  1. Fuse and relay check.  I purchased some new fuses, and replaced it.  I ensured all relays and other stuff was firmly seated.

2. I inspected all wiring for abrasions and issues.

3. Last, I went on eBay and found a listing for a new fan for $300.

Before getting the new fan, a good friend came over with a much better understanding of vehicle electronics, and helped me further diagnose.

We soon found the problem!  There are 3 wires that comprise the fan harness.  Black is ground, red is hot, and green carries a signal between 9v-12v and that basically allows the fan to operate on a scale based on engine temps.  It isn’t a straight on/off fan.

That little green wire had some sort of a short in the connectors.  We disassembled the connectors, reseated everything, and put everything back together.  I cleared the codes, and it has been great ever since.

So, before you panic and replace a $500 fan, check your wiring!

PS.  To the eBay seller in Miami that graciously let me cancel my order, thank you!!!

 

Product Install: Redneck Ram Hydro Assist Kit + Synergy Sector Shaft Brace

I always wanted to add hydro assist to my Jeep but questioned the PSC kit’s price point.  Being a simple system I figured others would work just as well or better.  Enter Redneck Ram from West Texas Offroad.

I found myself once again calling my buddy Dirk to help lend his expertise with this somewhat complicated install.

This was a two day install, as we could only work nights.

First things first, we put the Jeep on the lift, removed the front driver tire/wheel, tie rod, and sway bar links.   We also removed the pitman arm from the drag link (leaving the passenger side connected).

Product Review: SpiderWebShade for JKU

There are few things in life, than a hot Summer day in a Jeep, topless, and doorless.  I swear it is the best form of therapy available. But, there are days where the thermometer is in the triples where I have been stuck in traffic and have been roasting.

But there was never a middle ground.  It was either run the top as a bikini, or run topless and roast on those peak Summer days.

The fine mesh is really well made and is available in a lot of different colors.

Enter SpiderWebShade, the middle ground.

Product Install: Artec Aluminum 4 Door Bellypan Armor Kit

This is a VERY involved install that will require exhaust configurations, trips to the tool store, modifications, Jeep friends, and beer.  This is NOT a quick “bolt-up” installation as I thought it would be.  Understand that – you may require multiple days to get it done right.

This was one of the most significant installs I have done on my Jeep.

Product Install: M.O.R.E. Mount for ARB Dual Compressor

NOTE: This install includes the additional work for removing an aftermarket vacuum pump relocation bracket.  

I need to upgrade my air compressor, and in a major way.  I was using the Smittybilt portable, and the amount of time it took to air up four 35″ Duratracs was waaaay too long.  My wheeling friends can inflate their tires, have lunch, complete a crossword puzzle book, and read War and Peace by the time I am done.

So, a few weeks ago, I ordered the ARB CKMTA12 Twin compressor from Northridge.

Now, the question arose on where to mount this behemoth compressor.   So to answer this, I did what every self-respecting data geek would do; I made a table.

A table with considerations on mounting locations.

After weighing all the options and their pros and cons, I elected to install the compressor under the hood.  I trust ARB’s testing and figure it will survive well being so close to the firewall.  I will also be using this mostly with the hood open (tools and tires, no air lockers yet) so the cooling factor is less of a concern.

I ordered the MORE under hood bracket from Northridge.

Once it arrived, I happily skipped out to the garage to start the install, cold beer in hand.  I opened the hood, and went to lay out the bracket to ensure it would fit.  Houston, we have a problem. Continue reading Product Install: M.O.R.E. Mount for ARB Dual Compressor
