You got excited and pumped diesel into the gas tank of your Jeep. Now you’re going to have to go through with that jeep diesel conversion project after all. The easy way is to hire a diesel conversion specialist to do the work for you.
If you’re determined to go at it alone, here’s what’s coming next:
With enough gumption, you can stuff a Ford, GM, or Cummins diesel motor in your Jeep, but crate motors don’t come with everything you need.
Here’s a partial list of everything you’re going to need to find on your own:
A diesel Jeep Wrangler conversion kit comes prepackaged with the extra parts. These kits make home projects much easier to get started.
Create a workspace for your engine swap. A two-car home garage is adequate but uses both bays for your equipment and supplies.
Speaking of which, these are the essentials:
A professional gas to diesel conversion mechanic already has the shop and supplies to get the job done.
Strip the older parts out by following removal instructions in your repair manuals. Buy a manual if you don’t have one already.
You might be tempted to go through like a wrecker and smash up the used bits of Jeep you’re tired of, but don’t do it. Those old parts come in handy, and you might just need them again. Tag and store the leftovers.
Even a simple B4T Cummins conversion kit estimates at least 60 hours of total work time on the project from start to finish. It’s likely to take you longer depending on how much bodywork is required.
When you finally finish, and the last bolt is tight, it’s time to add your fluids and test your motor's operation. Make sure the garage is ventilated and follow the manufacturer’s recommended break in procedures.
Take it easy driving on your new engine for the first few weeks. It’s likely you will find mistakes that need correcting and some errors can lead to catastrophic failure.
