New Holland TT50A Coolant FAQs
How much coolant does a New Holland TT50A take?
The New Holland TT50A takes 13.4 gal | 50.7 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 13.4 gal | 50.7 L a lot of coolant for a New Holland TT50A?
Yes. For this tractor category, 13.4 gal | 50.7 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 TT50A?
Do not underestimate this refill. A 13.4 gal | 50.7 L system needs about 14 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 6.7 gal of concentrate and 6.7 gal of distilled water. In metric terms, that is roughly 11 x 5 L containers for a full premix refill.
Can I mix coolant types in a New Holland TT50A?
Because the listed coolant is extended-life OAT coolant, 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 the recommended coolant mixture ratio for the New Holland TT50A tractor is 50% antifreeze and 50% water, so do not run straight water except as a short emergency move.
How much concentrate and water does a New Holland TT50A need?
With the listed the recommended coolant mixture ratio for the New Holland TT50A tractor is 50% antifreeze and 50% water mix, a full 13.4 gal | 50.7 L refill works out to about 6.7 gal of antifreeze concentrate and 6.7 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 TT50A?
The listed cap pressure is 13 psi | 90 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.
