Baldwin Filters BW5086 Automotive Coolant Filter

Product Description

The BALDWIN FILTERS BW5086 is a spin-on coolant filter designed to remove contaminants and maintain coolant chemistry in heavy-duty and automotive cooling systems. It threads onto the filter head with an M36 x 2.0 thread and weighs 1.5 pounds. The BW5086 is installed by diesel technicians, fleet mechanics, and heavy-equipment service professionals performing scheduled coolant maintenance. Keeping coolant clean and properly conditioned helps prevent cavitation erosion, scale buildup, and liner pitting in high-load engines.

This filter is suited for use in heavy-duty diesel and automotive applications where coolant filtration is part of a routine service interval. It is a direct replacement for several OEM and aftermarket part numbers, making it a practical cross-reference choice for fleet shops and dealership service bays stocking a single SKU across multiple equipment brands. It fits systems using an M36 x 2.0 filter mount, which is common across a range of commercial and industrial engines.

Installation Notes

Coolant filter replacement is typically performed by a diesel mechanic or fleet technician during scheduled coolant service. Before removing the filter, relieve system pressure by allowing the engine to cool fully and loosening the coolant reservoir cap slowly. Use an appropriate filter wrench to remove the old unit, and hand-tighten the new filter until the gasket seats, then snug with a wrench per the filter head manufacturer guidance. Dispose of used coolant and filters in accordance with local environmental regulations.
