Capacity note
For the Massey Ferguson 425 Xtra, the listed cooling system capacity is 11.1 gal | 42 L. Buy slightly more coolant than the exact capacity so you have enough for topping off after air burps out.
Mixture note
50/50 antifreeze and water.
Radiator cap note
The radiator cap pressure listed for the Massey Ferguson 425 Xtra is 10 psi | 70 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 425 Xtra Coolant FAQs
How much coolant does a Massey Ferguson 425 Xtra take?
The Massey Ferguson 425 Xtra 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 425 Xtra?
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 425 Xtra?
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.
Can I mix coolant types in a Massey Ferguson 425 Xtra?
Because the listed coolant is the Massey Ferguson 425 Xtra tractor uses Hybrid Organic Acid Technology (HOAT) antifreeze, which combines the benefits of both inorganic and organic acids for corrosion, the clean move is to stay with the same approved chemistry. Do not casually mix it with old green conventional coolant; if the old coolant type is unknown, flush first or confirm what is already in the system. The listed mix is 50/50 antifreeze and water, so do not run straight water except as a short emergency move.
How much concentrate and water does a Massey Ferguson 425 Xtra need?
With the listed 50/50 antifreeze and water mix, a full 11.1 gal | 42 L refill works out to about 5.5 gal of antifreeze concentrate and 5.5 gal of distilled water. If using premix, do not add extra water unless the product label says to.
Can I use a different radiator cap on a Massey Ferguson 425 Xtra?
The listed cap pressure is 10 psi | 70 kPa. Use the same pressure rating when replacing it. The cap is part of the cooling system, not just a lid, and the wrong rating can cause boil-over, leaks or pressure problems.
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.
