Wrangler TJ Cooling System Maintenance

The jeepfan.com 2004 Wrangler TJ Unlimited has almost 195,000 miles on it. Since we have only owned it a short time it’s hard to know its maintenance history and recently we have noticed that the coolant has been boiling in the overflow bottle. Even more recently it boiled so bad that it puked up antifreeze …

Wrangler JL 3.6L V6 Oil Change

The 2018+ Wrangler JL uses the same 3.6L V6 as the 2012-2018 Wrangler JK. There are some internal tweaks, but it’s mostly the same on the outside. A redesign of the top engine cover makes accessing the filter possible without removing the cover. Changing your oil yourself can save you some money but mostly it …

How Electronic Start Stop ESS Works on the Jeep Wrangler JL

The 3.6L Pentastar V6 in the new Wrangler JL utilizes the Electronic Start Stop System (ESS).

Determining the Tire Contact Patch

You buy new (and larger) tires and possibly wheels for your Jeep and you wonder what’s the proper pressure.  It’s often different than the stock tires since the larger tires are likely a different weight rating and constructed a bit different.  Finding your proper pressure is done by reading the contact patch. Just how do …

Jeep Wrangler JK VIN Guide

We’ve been compiling information to create a VIN decoder for the Wrangler JK Series which ran from 2007 to 2017.  Some information has been difficult to obtain as years have progressed, modifications will be made as it becomes available. The VIN plate on a JK can be easiest located through the front of the driver …

Jeep Wrangler 2017 Model Changes

It’s likely 2017 will be the final year of the JK.  Hard to believe that 10 years have passed since the release of the first ever four door Wrangler that caused such a stir in the Jeep community.  The controversial Jeep quickly turned into possibly the most successful open roof style Jeep model ever.  Just …
