COLLANT FILTER,SPIN ON,DONALDSON BLUE/// DBC4089

It uses Donaldson’s Synteq media to capture contaminants down to 50 microns with 99% efficiency, protecting the cooling system from scale, rust, and debris. Regular replacement (typically at 150,000‑mile extended service intervals on Volvo applications) helps maintain coolant chemistry, prevent overheating, and extend water‑pump and radiator life. While the P554089 part number cross‑references directly to Donaldson DBC4089, it is a common replacement filter for many on‑highway trucks that use a spin‑on coolant filter with an M16 x 1.5 thread.
