New Holland T9.615 Coolant FAQs
How much coolant does a New Holland T9.615 take?
The New Holland T9.615 takes 21.1 gal | 79.9 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 T9.615 coolant capacity normal?
Yes, 21.1 gal | 79.9 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 T9.615?
Do not underestimate this refill. A 21.1 gal | 79.9 L system needs about 22 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 10.6 gal of concentrate and 10.6 gal of distilled water. In metric terms, that is roughly 16 x 5 L containers for a full premix refill.
What coolant should I use in a New Holland T9.615?
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 New Holland T9.615 need?
With the listed 50/50 antifreeze and water mix, a full 21.1 gal | 79.9 L refill works out to about 10.6 gal of antifreeze concentrate and 10.6 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 T9.615?
The listed cap pressure is 10 psi | 70 kPa. Use the same pressure rating when replacing it. The cap is part of the cooling system, not just a lid, and the wrong rating can cause boil-over, leaks or pressure problems.
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.
