Product Description

The BALDWIN FILTERS BW5137 is a spin-on engine coolant filter designed to remove contaminants from heavy-duty cooling systems. With an outside diameter of 3.69 inches and an overall length of 4.406 inches, this filter fits a range of diesel and gasoline-powered equipment commonly serviced by fleet mechanics and diesel technicians. It features an 11/16-16 inch thread size and a 50-micron filtration rating, providing consistent particulate control in coolant circuits. The BW5137 ships with a G381-A I gasket included, supporting a clean, leak-free installation right out of the box.

This filter is suited for use in trucks, construction equipment, and agricultural machinery with coolant systems in the 11 to 20 gallon capacity range. It is noted to fit Peterbilt trucks and serves as a direct spin-on replacement in systems that originally use compatible OEM coolant filters across multiple manufacturers. Diesel mechanics and fleet service technicians will find it applicable across a broad range of on-highway and off-highway equipment.

Installation Notes

Coolant filter service should be performed by a qualified diesel mechanic or fleet technician. Allow the engine to cool completely and relieve system pressure before removing the old filter. Apply a light coat of fresh coolant to the gasket before threading the new filter on by hand, then snug with a filter wrench. Inspect for leaks after returning the system to operating temperature.
