New Holland Boomer 46D Coolant FAQs
How much coolant does a New Holland Boomer 46D take?
The New Holland Boomer 46D takes 10.5 gal | 40 L of coolant. That is well above the normal utility tractor benchmark shown here, so treat it as a full cooling-system service job, not a quick top-up.
Is 10.5 gal | 40 L a lot of coolant for a New Holland Boomer 46D?
Yes. For this tractor category, 10.5 gal | 40 L is well above normal. 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 Boomer 46D?
Do not underestimate this refill. A 10.5 gal | 40 L system needs about 11 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 5.2 gal of concentrate and 5.2 gal of distilled water. In metric terms, that is roughly 8 x 5 L containers for a full premix refill.
Can I mix coolant types in a New Holland Boomer 46D?
Because the listed coolant is extended-life OAT coolant meeting MAT 3724, the clean move is to stay with the same approved chemistry. Do not casually mix it with old green conventional coolant; if the old coolant type is unknown, flush first or confirm what is already in the system. 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 Boomer 46D need?
With the listed 50/50 antifreeze and water mix, a full 10.5 gal | 40 L refill works out to about 5.2 gal of antifreeze concentrate and 5.2 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 Boomer 46D?
The listed cap pressure is 7 psi | 48 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.
