The GM 2.4L Engine and Its Industrial Applications
General Motors’ 2.4L inline-four engine, known internally as the LE5 or LN2 depending on configuration, was originally developed for passenger vehicles but later adapted for industrial use. In forklifts, aerial lifts, and compact construction equipment, this engine became a reliable powerplant due to its balance of torque, fuel efficiency, and ease of maintenance. By the mid-2000s, GM had partnered with equipment manufacturers like Snorkel, Hyster, and Yale to integrate the 2.4L into machines such as the TB60 lift and various warehouse forklifts. These industrial variants often featured simplified electronics and heavy-duty cooling systems to suit demanding work environments.
Challenges in Identifying the Correct Filter
Unlike automotive applications where VIN-based lookup is standard, industrial engines often lack centralized databases for parts. When a filter falls off or is missing, technicians must rely on physical inspection, cross-referencing, or trial-and-error. In one case, a technician spent over three hours searching online and contacting dealers, only to find that most parts suppliers required an exact filter number to proceed—highlighting the gap in support for industrial adaptations of automotive engines.
Recommended Oil Filter Models
For GM 2.4L engines used in industrial equipment, the following filters are commonly compatible:
In Ohio, a technician working on a Snorkel TB60 lift found the oil filter missing and the machine parked in front of a sheriff’s department entrance. With no time to waste, he jerry-rigged a temporary solution to move the lift, then sourced a Wix 51040 the following Monday. In Alberta, a heavy-duty mechanic confirmed that most GM 2.4L industrial engines he serviced used the same filter, simplifying inventory management across multiple brands.
Best Practices for Maintenance
Identifying the correct oil filter for a GM 2.4L engine in industrial equipment can be frustrating without a part number, but common filters like the Wix 51040 and NAPA Gold 1040 offer reliable solutions. These engines, though derived from automotive platforms, perform admirably in lifts and forklifts when properly maintained. Technicians should prioritize proactive inventory management and routine inspection to ensure uptime and avoid costly delays.

Recommended Oil Filter Models
For GM 2.4L engines used in industrial equipment, the following filters are commonly compatible:
- Wix 51040: A high-quality spin-on filter with anti-drainback valve and 21-micron nominal filtration. Known for durability in high-hour applications.
- NAPA Gold 1040: Manufactured by Wix, this filter offers identical specifications and is widely available in North America.
- Fram PH3387A: A budget option with basic filtration, suitable for light-duty use or emergency replacement.
- ACDelco PF47E: OEM-grade filter used in GM passenger vehicles, often interchangeable with industrial variants.
- Spin-On Filter: A self-contained unit that screws directly onto the engine block, simplifying replacement.
- Micron Rating: Indicates the size of particles the filter can trap. Lower numbers mean finer filtration.
- Anti-Drainback Valve: Prevents oil from draining out of the filter when the engine is off, reducing wear during startup.

Best Practices for Maintenance
- Keep Spare Filters On Hand: Especially for remote job sites or emergency service scenarios.
- Label Filters by Equipment: Use tags or bins to associate filters with specific machines to avoid confusion.
- Change Oil Every 250–300 Hours: Industrial engines often run longer and hotter than automotive counterparts.
- Inspect for Leaks After Installation: A misaligned gasket or over-tightened filter can cause oil loss and engine damage.
