Capacity note
For the Massey Ferguson 690T, the listed cooling system capacity is 12.5 gal | 47.3 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 690T is 7 psi | 48 kPa. Do not replace it with a random cap unless the pressure rating matches.

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 690T Coolant FAQs
How much coolant does a Massey Ferguson 690T take?
The Massey Ferguson 690T takes 12.5 gal | 47.3 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 12.5 gal | 47.3 L a lot of coolant for a Massey Ferguson 690T?
Yes. For this tractor category, 12.5 gal | 47.3 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 690T?
Do not underestimate this refill. A 12.5 gal | 47.3 L system needs about 13 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 6.2 gal of concentrate and 6.2 gal of distilled water. In metric terms, that is roughly 10 x 5 L containers for a full premix refill.
What coolant should I use in a Massey Ferguson 690T?
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. 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 690T need?
With the listed 50/50 antifreeze and water mix, a full 12.5 gal | 47.3 L refill works out to about 6.2 gal of antifreeze concentrate and 6.2 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 690T?
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.
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.
