New Holland 5640 Coolant FAQs
How much coolant does a New Holland 5640 take?
The New Holland 5640 takes 2.2 gal | 8.5 L of coolant. That is about normal for the compact tractor benchmark shown here, so plan it like a standard drain-and-refill rather than a tiny top-up.
Is the New Holland 5640 coolant capacity normal?
Yes, 2.2 gal | 8.5 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 5640?
This is a manageable refill amount. A 2.2 gal | 8.5 L system needs about 3 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 1.1 gal of concentrate and 1.1 gal of distilled water. In metric terms, that is roughly 2 x 5 L containers for a full premix refill.
What coolant should I use in a New Holland 5640?
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 5640 need?
With the listed 50/50 antifreeze and water mix, a full 2.2 gal | 8.5 L refill works out to about 1.1 gal of antifreeze concentrate and 1.1 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 5640?
The listed cap pressure is 7 psi | 48.3 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.
