Case IH Farmall 50B Coolant FAQs
How much coolant does a Case IH Farmall 50B take?
The Case IH Farmall 50B takes 15.9 gal | 59.9 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 15.9 gal | 59.9 L a lot of coolant for a Case IH Farmall 50B?
Yes. For this tractor category, 15.9 gal | 59.9 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 Case IH Farmall 50B?
Do not underestimate this refill. A 15.9 gal | 59.9 L system needs about 16 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 8 gal of concentrate and 8 gal of distilled water. In metric terms, that is roughly 12 x 5 L containers for a full premix refill.
Can I mix coolant types in a Case IH Farmall 50B?
Because the listed coolant is extended-life OAT coolant, 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 the recommended coolant mixture ratio for the Case IH Farmall 50B tractor is 50% antifreeze and 50% water, so do not run straight water except as a short emergency move.
How much concentrate and water does a Case IH Farmall 50B need?
With the listed the recommended coolant mixture ratio for the Case IH Farmall 50B tractor is 50% antifreeze and 50% water mix, a full 15.9 gal | 59.9 L refill works out to about 8 gal of antifreeze concentrate and 8 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 Case IH Farmall 50B?
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 caseih.com website before draining, flushing or refilling the cooling system.
