New Holland 1120 Coolant FAQs
How much coolant does a New Holland 1120 take?
The New Holland 1120 takes 4.8 gal | 18.2 L of coolant. That is above the average compact tractor benchmark, so buy enough coolant before starting instead of relying on one spare jug.
Is 4.8 gal | 18.2 L a lot of coolant for a New Holland 1120?
Yes. For this tractor category, 4.8 gal | 18.2 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 1120?
This is a manageable refill amount. A 4.8 gal | 18.2 L system needs about 5 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 2.4 gal of concentrate and 2.4 gal of distilled water. In metric terms, that is roughly 4 x 5 L containers for a full premix refill.
How much concentrate and water does a New Holland 1120 need?
With the listed 50/50 antifreeze and water mix, a full 4.8 gal | 18.2 L refill works out to about 2.4 gal of antifreeze concentrate and 2.4 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 1120?
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.
When should the New Holland 1120 coolant be changed?
Use whichever limit comes first for the New Holland 1120: every 1,500 hours or 3 years. Low-hour tractors can still age out on time, because corrosion protection gets weaker even when the coolant still looks clean.
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.
