Jeep 2.4L (148 cu in) firing order — diagram & guide

Over the years, Jeep experimented with a lot of six-cylinder engines for the entry-level models of their vehicles, but a 2.4-liter was pretty striking news back in the day. It’s one of those engines that didn’t seem as good as V6 or V8 versions but made pretty stable options for low-end trims of Jeep cars.

Even though these engines proved to be durable, it can’t hurt to explore more about the Jeep 2.4L (148 cu in) firing order and that’s exactly what we’ll provide you with in this guide. Not only will we clear out your doubts about the firing order, but we’ll also discuss the different versions of this engine and cylinder layouts, so stand by for details.

Jeep 2.4L firing order

The 2.4-liter four-cylinder made its debut in 2007 and it was based on the “World” engine developed in partnership with Chrysler. As a four-cylinder, the Jeep 2.4L firing order is 1-3-4-2 and it’s one of the few options possible since these engines can never fire straight from 1 to 4.

It would put too much stress on the crank and that’s why most four-cylinder engines use this firing order. However, confusion was caused once Jeep revealed another 2.4-liter engine in 2014, so we’ll get to that one as well.

Jeep 2.4L Tigershark firing order

As a new and updated version of the four-cylinder engine, the Jeep 2.4L Tigershark firing order is 1-3-4-2 just like with the previous one. There were only some minor changes that Jeep has made using the variable valve timing and the multi-air technology to optimize fuel efficiency and power supply.

So, for anyone wondering if the new 2.4-liter four-cylinder differs from the previous one – it kind of does in terms of the VVT technology, but the firing order is still the same.

These engines were pretty classic in terms of the cylinder arrangement as they came with an inline-four configuration. This means that the engine was placed in the engine bay with cylinders 1 to 4 going in a straight line from the front end to the rear end of the engine.

So, you’ll find the first cylinder being close to the radiator, and the fourth cylinder reaching out towards the rear end of the engine.

Jeep 2.4L vehicle applications

Considering that the 2.4-liter four-cylinder and the Tigershark engines have been produced for 15 years now, Jeep put those in quite a few models. We wanted to give you a full list of these in the period between 2007 and 2023 so you won’t mix up the firing order:

• Jeep Cherokee
• Jeep Renegade
• Jeep Compass
• Jeep Patriot

The first generation of this engine was only available on the Patrior and the Cherokee, while the Compass and Renegade were only available with the Tigershark version.

Our take

Ultimately, we have to say that the 2.4-liter engine was a decent option for Jeep cars and it still is in its Tigershark form. So, as long as you maintain it properly and put the Jeep 2.4L firing order to good use when checking the cylinders, it should be a silky smooth ride.
