The TJ Wrangler 2.5 4 cylinder engine was the result of a three year development project by American Motors to engineer a Jeep-specific system that would combine off-road performance and durability with lightweight efficiency, and it delivered. But even the best-maintained machine is bound to need a few tune-ups and repairs along the road. At 4 Wheel Parts you'll find a full suite of top-quality replacement parts, from valve cover grommets and oil pan plugs to pistons and pins. For a quick overview, check out our Jeep 2.5 engine diagram.

The Value of Good Maintenance
The engine is the beating heart of your machine. In addition to staying on top of routine maintenance, reacting quickly to fix leaks and repair damaged parts is crucial: especially when your rig is a rough-riding Jeep.

Avoiding Engine Leaks
Oil leaks are one of the most common engine issues, and Jeeps are notorious for "marking their spot". Most 2.5 and 4.0L systems begin to develop oil leaks at around 100-150K miles. While plenty of Jeep owners resign themselves to perpetual dripping, neglecting a faulty seal is always a gamble. A small leak can become a big one in the blink of an eye when treading rugged terrain, and a sudden drop in oil levels starves the engine, leading to potentially catastrophic damage. In addition to replacing your filter with each oil change, it's important to keep a close eye on the integrity of all engine seals.

Small Parts, Big Jobs
Every part of your Jeep engine has been precisely designed and positioned to perform an important function. As with leaks, damaged or misaligned parts can only get worse, and can easily lead to even more devastating problems.

Easy Ordering and Installation Expertise
Track down exactly the part you need in seconds using the search bar or the Jeep 4.0 engine exploded view to order online, or visit us at one of our 60+ locations across North America and let one of our experienced technicians handle installation.
