Capacity note
For the New Holland T8020, the listed cooling system capacity is 18.5 gal | 70 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 New Holland T8020 is 15 psi | 103 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.
New Holland T8020 Coolant FAQs
How much coolant does a New Holland T8020 take?
The New Holland T8020 takes 18.5 gal | 70 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 T8020 coolant capacity normal?
Yes, 18.5 gal | 70 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 T8020?
Do not underestimate this refill. A 18.5 gal | 70 L system needs about 19 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 9.2 gal of concentrate and 9.2 gal of distilled water. In metric terms, that is roughly 14 x 5 L containers for a full premix refill.
Can I mix coolant types in a New Holland T8020?
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 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 T8020 need?
With the listed 50/50 antifreeze and water mix, a full 18.5 gal | 70 L refill works out to about 9.2 gal of antifreeze concentrate and 9.2 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 T8020?
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.
