Massey Ferguson 5S.135 Extra Coolant Notes
| Engine horsepower | 135 hp | 100.7 kW |
|---|---|
| Engine displacement | 4.4 L | 268 cu in |
| Capacity note | For the Massey Ferguson 5S.135, the listed cooling system capacity is 2.6 gal | 9.9 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 5S.135 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 5S.135 Coolant FAQs
How much coolant does a Massey Ferguson 5S.135 take?
The Massey Ferguson 5S.135 takes 2.6 gal | 9.9 L of coolant. That is about normal for the compact tractor benchmark shown here, so plan it like a standard drain-and-refill rather than a tiny top-up.
Is the Massey Ferguson 5S.135 coolant capacity normal?
Yes, 2.6 gal | 9.9 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 5S.135?
This is a manageable refill amount. A 2.6 gal | 9.9 L system needs about 3 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 1.3 gal of concentrate and 1.3 gal of distilled water. In metric terms, that is roughly 2 x 5 L containers for a full premix refill.
How much concentrate and water does a Massey Ferguson 5S.135 need?
With the listed 50/50 antifreeze and water mix, a full 2.6 gal | 9.9 L refill works out to about 1.3 gal of antifreeze concentrate and 1.3 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 5S.135?
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 5S.135 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.
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.
