Mixture note
50/50 antifreeze and water.
Radiator cap note
The radiator cap pressure listed for the Massey Ferguson 6S.135 is 10 psi | 69 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 6S.135 Coolant FAQs
How much coolant does a Massey Ferguson 6S.135 take?
The Massey Ferguson 6S.135 takes 10.2 gal | 38.6 L of coolant. That is about normal for the row-crop tractor benchmark shown here, so plan it like a standard drain-and-refill rather than a tiny top-up.
Is the Massey Ferguson 6S.135 coolant capacity normal?
Yes, 10.2 gal | 38.6 L lands about where you would expect for this tractor category. The main thing is buying enough for a complete refill plus a small top-off amount.
How many coolant jugs do I need for a Massey Ferguson 6S.135?
Do not underestimate this refill. A 10.2 gal | 38.6 L system needs about 11 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 5.1 gal of concentrate and 5.1 gal of distilled water. In metric terms, that is roughly 8 x 5 L containers for a full premix refill.
What coolant should I use in a Massey Ferguson 6S.135?
The listed coolant is 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. 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 6S.135 need?
With the listed 50/50 antifreeze and water mix, a full 10.2 gal | 38.6 L refill works out to about 5.1 gal of antifreeze concentrate and 5.1 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 6S.135?
The listed cap pressure is 10 psi | 69 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.
