New Holland 8670 Coolant FAQs
How much coolant does a New Holland 8670 take?
The New Holland 8670 takes 15 gal | 56.8 L of coolant. That is above the average row-crop tractor benchmark, so buy enough coolant before starting instead of relying on one spare jug.
Is 15 gal | 56.8 L a lot of coolant for a New Holland 8670?
Yes. For this tractor category, 15 gal | 56.8 L is above average. 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 8670?
Do not underestimate this refill. A 15 gal | 56.8 L system needs about 15 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 7.5 gal of concentrate and 7.5 gal of distilled water. In metric terms, that is roughly 12 x 5 L containers for a full premix refill.
What coolant should I use in a New Holland 8670?
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 8670 need?
With the listed 50/50 antifreeze and water mix, a full 15 gal | 56.8 L refill works out to about 7.5 gal of antifreeze concentrate and 7.5 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 8670?
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.
