Baldwin B5089 Coolant Filter Application

The Baldwin B5089 is a spin-on coolant filter designed for automotive and heavy-duty cooling systems. It removes particulate contamination down to a 20-micron rating without adding supplemental coolant additives. The cartridge includes an integrated gasket for a secure seal during installation. This unit suits maintenance on compatible equipment requiring chemical-free filtration.

Thread Size and Clearance Verification

Confirm that the engine mounting boss accepts an 11/16 inch thread before ordering. Measure available space to accommodate the 4 3/8 inch installed height and the 3 11/16 inch outside diameter. Ensure the cooling system operates with coolant fluid compatible with a non-chemical spin-on design. Cross-reference the original equipment part number to validate fitment.

Fleets Needing Chemical-Free Spin-On Filtration

This filter serves operators who require a 20-micron coolant filter without supplemental chemical treatment. It is not suited for systems demanding a charged coolant filter that releases corrosion inhibitors. Buyers needing a different thread pitch, a larger micron rating, or a cartridge-style element should look at alternative configurations.

Questions about this item

Does the Baldwin B5089 coolant filter come with a gasket or must I order one separately?

The filter includes an integral gasket so no separate seal is required.

When should I choose the 20 micron rating over a finer or coarser option?

A 20 micron rating balances particle capture with coolant flow for typical heavy-duty cooling systems.

How does the 11/16 inch thread size affect installation on my equipment?

The 11/16 inch thread matches standard spin-on coolant filter heads used on many commercial engines.
