Description

When your Massey starts running hot or you notice coolant puddles under the tractor after a day’s work, it’s time for a new water pump. This complete water pump assembly protects valuable engine investments by keeping coolant circulating properly through your AD4-203 diesel. Don’t let overheating turn a good work day into a breakdown that costs you time and money.

What You’re Getting

Complete assembly with pulley included – no need to hunt for separate parts
Precision-machined components with high-quality impeller that maximizes coolant circulation efficiency
Durable seals and bearings ensure long-term reliability under the demands of farm work
Direct replacement for your original pump – fits like the factory intended

Built for Real Farm Work

This pump is designed specifically for Massey Ferguson 65, 165, and 255 tractors equipped with the dependable AD4-203 diesel engine. These robust machines handle diverse agricultural operations including row crop farming and heavy field work. Whether you’re pulling a plow, running a mower, or pushing feed with a loader, this pump keeps your engine running at the right temperature.

Made to Last

Engineered to meet or exceed original equipment specifications, this water pump is built to handle the heat, vibration, and long hours that come with farm life. The included pulley maintains proper belt alignment and drive ratios, so your cooling system works exactly as Massey Ferguson designed it.

Installation Notes

Drain cooling system completely before installation and thoroughly clean all mating surfaces. Since you’ll have the system apart, it’s a good time to check your thermostat and flush any old coolant. Contaminated coolant shortens pump life, so start fresh with new coolant and proper mixture. The pulley’s already mounted, so installation is straightforward once the old pump’s out.
