New Holland T7.290 Coolant FAQs
How much coolant does a New Holland T7.290 take?
The New Holland T7.290 takes 16.5 gal | 62.5 L of coolant. That is about normal for the large ag tractor benchmark shown here, so plan it like a standard drain-and-refill rather than a tiny top-up.
Is the New Holland T7.290 coolant capacity normal?
Yes, 16.5 gal | 62.5 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 New Holland T7.290?
Do not underestimate this refill. A 16.5 gal | 62.5 L system needs about 17 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 8.2 gal of concentrate and 8.2 gal of distilled water. In metric terms, that is roughly 13 x 5 L containers for a full premix refill.
Can I mix coolant types in a New Holland T7.290?
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 T7.290 need?
With the listed 50/50 antifreeze and water mix, a full 16.5 gal | 62.5 L refill works out to about 8.2 gal of antifreeze concentrate and 8.2 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 New Holland T7.290?
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 newholland.com website before draining, flushing or refilling the cooling system.
