New Holland T9.435 Coolant FAQs
How much coolant does a New Holland T9.435 take?
The New Holland T9.435 takes 30.5 gal | 115 L of coolant. That is above the average large ag tractor benchmark, so buy enough coolant before starting instead of relying on one spare jug.
Is 30.5 gal | 115 L a lot of coolant for a New Holland T9.435?
Yes. For this tractor category, 30.5 gal | 115 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 T9.435?
Do not underestimate this refill. A 30.5 gal | 115 L system needs about 31 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 15.2 gal of concentrate and 15.2 gal of distilled water. In metric terms, that is roughly 23 x 5 L containers for a full premix refill.
What coolant should I use in a New Holland T9.435?
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 T9.435 need?
With the listed 50/50 antifreeze and water mix, a full 30.5 gal | 115 L refill works out to about 15.2 gal of antifreeze concentrate and 15.2 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 T9.435?
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.
