Mixture note
50/50 antifreeze and water.
Radiator cap note
The radiator cap pressure listed for the New Holland T9.600 is 15 psi | 103 kPa. Do not replace it with a random cap unless the pressure rating matches.

New Holland T9.600 Coolant FAQs
How much coolant does a New Holland T9.600 take?
The New Holland T9.600 takes 66 gal | 249.8 L of coolant. That is well above the normal large ag tractor benchmark shown here, so treat it as a full cooling-system service job, not a quick top-up.
Is 66 gal | 249.8 L a lot of coolant for a New Holland T9.600?
Yes. For this tractor category, 66 gal | 249.8 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 New Holland T9.600?
Do not underestimate this refill. A 66 gal | 249.8 L system needs about 66 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 33 gal of concentrate and 33 gal of distilled water. In metric terms, that is roughly 50 x 5 L containers for a full premix refill.
Can I mix coolant types in a New Holland T9.600?
Because the listed coolant is extended-life OAT coolant meeting MAT 3724, 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 New Holland T9.600 need?
With the listed 50/50 antifreeze and water mix, a full 66 gal | 249.8 L refill works out to about 33 gal of antifreeze concentrate and 33 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 New Holland T9.600?
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.
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 newholland.com website before draining, flushing or refilling the cooling system.
