Baldwin BW5071 Coolant Filter

The Baldwin BW5071 is a spin-on coolant filter designed for heavy-duty cooling systems. Its 11/16 inch thread size fits compatible filter heads on commercial vehicles and industrial equipment. The unit uses a 20 micron rating to capture contaminants that degrade coolant chemistry and damage water pumps or radiators.

Replaces standard coolant filters without

This filter includes four units of BTA PLUS formula additive that releases conditioners during operation. The jump is worth it when maintenance intervals are extended or when plain filters allow additive depletion between service intervals. Systems running straight water or conventional coolant without a pre-charge benefit most from the integrated chemistry.

Sustained load maintains additive release over

Under continuous engine operation the spin-on canister maintains structural integrity while the BTA PLUS additive dissolves at a controlled rate. This steady release protects cylinder liners and aluminium components from cavitation and corrosion longer than a burst-dose treatment. The filter media continues trapping particles at the rated 20 micron level throughout the duty cycle.

Questions about this item

What thread size does the BW5071 coolant filter use for mounting?

The filter mounts with an 11/16 in thread, matching the specification listed for this Baldwin spin-on unit.

How is the spin-on filter installed, and what step is often missed?

Screw the filter onto the 11/16 in thread by hand until the gasket contacts the base, then tighten the recommended additional turn; skipping the gasket-contact check causes leaks.

When does the 20 micron filter element need replacement?

Replace the element at the engine manufacturer's coolant service interval or when the BTA PLUS additive package is depleted, whichever comes first.
