Although it was installed on many different models between 1988 and 1999, the 2.4-liter Nissan KA24E engine—also known as KA24 for short—is best known for the Pathfinder and Terrano SUVs. Many of the concerned pickup trucks have this power unit under the hood.
The KA20DE and KA24DE internal combustion engines are also members of the KA family.
The engine was mounted on:
- Nissan 240SX S13 in 1989 – 1994;
- Nissan Bluebird U12 in 1988 – 1992;
- Nissan Navara 1 (D21) in 1990 – 1997;
- Nissan Navara 2 (D22) in 1997 – 1999;
- Nissan Pathfinder 1 (WD21) in 1990 – 1995;
- Nissan Prairie M11 in 1988 – 1998;
- Nissan Stanza U12 in 1989 – 1992;

Disadvantages of the KA24E engine
Owners typically lament excessively high fuel or oil consumption;
Since there are no hydraulic lifters here, the valves must be adjusted on a regular basis;
Impact causes the engine pan to wrinkle easily, which increases the risk of the oil receiver becoming blocked;
It is frequently already necessary to replace the timing chain or its tensioner closer to 250,000 kilometers;
Cheap oil causes the power unit to cokes quickly, so it dislikes it.
