Engine Options
Which engine does your Wrangler have?
Four Wranglers, four sets of engines. The YJ paired the 2.5L four with a carbureted 4.2L six until 1990 and the fuel-injected 4.0L from 1991. The TJ kept the 2.5L to 2002, moved to a 2.4L for 2003 and had the 4.0L throughout. The JK had the 3.8L and then the 3.6L Pentastar, and the JL has offered the Pentastar, a 2.0L turbo, a diesel, a plug-in hybrid and a V8.
The 2.5L and 4.0L span the YJ and TJ, and the 3.6L the JK and JL, but in each case the same size is not the same engine from one end of its run to the other. The table below lists what was offered when. There was no 1996 Wrangler. Both the old JK and the new JL were sold as 2018 models, so for a 2018 Wrangler we check the VIN before anything else.

Before You Order
What to check before you order
Two 2018 Wranglers
The JK stayed in production into 2018 and was sold alongside the new JL, both as 2018 models. The VIN tells us which one you have.
4.2L or 4.0L — YJ
A 1987–1990 YJ six-cylinder is the carbureted 4.2L; a 1991–1995 is the fuel-injected 4.0L. Both are AMC straight-sixes, but they differ in displacement, fuel system and electronics, so one is not a drop-in for the other.
Which four-cylinder
The 2.5L ran from 1987 to 2002 across the YJ and TJ, and its 1987–1990 throttle-body version has a different intake, fuel system and electronics from the later multi-point engine. The 2.4L that replaced it for 2003 is a different engine with different transmissions behind it.
4xe is a hybrid
The 4xe pairs the 2.0L turbo with electric motors and a high-voltage battery. Tell us if your Jeep is a 4xe.
Have your VIN ready
With the VIN we can confirm the engine, model year and body before we quote, which avoids ordering the wrong version.
Common Problems
Common Wrangler engine problems
Carburetor and vacuum faults — 1987–1990 4.2L
The 4.2L’s computer-controlled feedback carburetor and its maze of vacuum hoses are notorious for rough idling, stalling and hard starting as they age. A YJ that runs this badly often has a fuel or vacuum fault rather than a worn-out engine, so have that checked first.
Cracked cylinder head — 4.0L
The 4.0L’s “0331” casting cylinder head, introduced for 2000, is known for cracking between cylinders 3 and 4, causing coolant loss and coolant in the oil.
Oil consumption — 2007–2011 3.8L
The 3.8L is known for burning oil as the miles build. Left unchecked between changes, the level can fall far enough to starve the bearings, which ends in a replacement engine.
Cylinder head wear — 2012–2013 3.6L
Valve guide and seat wear in the left cylinder head causes misfires. Chrysler extended the warranty on that head to 10 years or 150,000 miles; the cover has now expired.
Pentastar tick — 3.6L
A ticking from the top of the engine is usually a failed rocker-arm roller bearing. Caught early it is a rocker-arm and lifter job; left running, it wears the camshaft lobe and can cause a misfire.

FAQ
Wrangler engine questions, answered
Was there a 1996 Wrangler?
No. The YJ ended with the 1995 models and the TJ began with the 1997s. The tenth character of your VIN gives the model year: S for 1995, V for 1997.
Will a 4.0L from a Cherokee or Grand Cherokee fit my YJ or TJ?
The 4.0L was also used in the 1987–2001 Cherokee XJ and the Grand Cherokee to 2004, but the versions differ by vehicle and year. Send us your VIN and we will match the right one.
Is the 3.6L in a JK the same as in a JL?
Both are the 3.6L Pentastar, but the JL has a redesigned version of the engine. We match by generation and model year rather than treating every 3.6L as the same.
Did the Wrangler come with a diesel?
Yes, the 3.0L EcoDiesel on four-door JLs from 2020 to 2023. It is the only diesel offered on a US-market Wrangler.
Is the engine covered by a warranty?
Yes. Every engine we sell is covered by warranty, and extended cover is available at extra cost. The full terms are in our Warranty Policy.
