Capacity note
For the Massey Ferguson 398, the listed cooling system capacity is 4.1 gal | 15.5 L. Buy slightly more coolant than the exact capacity so you have enough for topping off after air burps out.
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 398 is 15 psi | 103 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 398 Coolant FAQs
How much coolant does a Massey Ferguson 398 take?
The Massey Ferguson 398 takes 4.1 gal | 15.5 L of coolant. That is below the average utility tractor benchmark, so it is not a huge coolant job, but you still want spare premix for topping off.
Is 4.1 gal | 15.5 L a small coolant capacity for a Massey Ferguson 398?
It is below average compared with the benchmark on this page. That makes the job cheaper, but it does not make coolant choice or bleeding less important.
How many coolant jugs do I need for a Massey Ferguson 398?
This is a manageable refill amount. A 4.1 gal | 15.5 L system needs about 5 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 2 gal of concentrate and 2 gal of distilled water. In metric terms, that is roughly 4 x 5 L containers for a full premix refill.
What coolant should I use in a Massey Ferguson 398?
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 398?
The listed cap pressure is 15 psi | 103 kPa. That higher-pressure cap helps raise the boiling point, but only if the radiator neck, hoses and overflow path are in good shape. A weak cap or damaged seat can still cause coolant loss.
When should the Massey Ferguson 398 coolant be changed?
The listed interval is every 500 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.
