Mixture note
Use the coolant type listed above and match the antifreeze/water mix to the operator manual and local freezing conditions.
Radiator cap note
The radiator cap pressure listed for the Massey Ferguson 251XE is 7 psi | 48 kPa. Do not replace it with a random cap unless the pressure rating matches.
Refill note
Refill slowly, run the tractor until warm with the heater circuit open if fitted, let it cool, then recheck the coolant level. Never remove a hot radiator cap under pressure.
Massey Ferguson 251XE Coolant FAQs
How much coolant does a Massey Ferguson 251XE take?
The Massey Ferguson 251XE takes 11.1 gal | 42 L of coolant. That is well above the normal utility tractor benchmark shown here, so treat it as a full cooling-system service job, not a quick top-up.
Is 11.1 gal | 42 L a lot of coolant for a Massey Ferguson 251XE?
Yes. For this tractor category, 11.1 gal | 42 L is well above normal. This is the sort of refill where you want all coolant on hand before draining, because stopping halfway through the job is annoying and messy.
How many coolant jugs do I need for a Massey Ferguson 251XE?
Do not underestimate this refill. A 11.1 gal | 42 L system needs about 12 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 5.5 gal of concentrate and 5.5 gal of distilled water. In metric terms, that is roughly 9 x 5 L containers for a full premix refill.
What coolant should I use in a Massey Ferguson 251XE?
The listed coolant is 50/50 ethylene glycol-based coolant. Ethylene glycol tells you the base coolant, but the additive package still matters on diesel engines, so match the manual or an approved equivalent.
Can I use a different radiator cap on a Massey Ferguson 251XE?
The listed cap pressure is 7 psi | 48 kPa. That is a lower-pressure cap, so do not upgrade it to a higher-pressure cap just because it sounds stronger. Too much cap pressure can stress hoses, radiator seams and older seals.
When should the Massey Ferguson 251XE coolant be changed?
The listed interval is every 600 hours. Hour-based service matters most on working tractors that spend long periods hot under load.
Official information note
Mistakes do happen. Coolant specs can change by year, engine, market, radiator option and coolant chemistry. Check the operator manual, parts book and official masseyferguson.com website before draining, flushing or refilling the cooling system.
