300 hp | 223.7 kW
Engine displacement
11 L | 674 cu in
Capacity note
For the Case IH 4894, the listed cooling system capacity is 18 gal | 68.1 L. Buy slightly more coolant than the exact capacity so you have enough for topping off after air burps out.
Mixture note
50/50 antifreeze and water.
Radiator cap note
The radiator cap pressure listed for the Case IH 4894 is 13 psi | 90 kPa. Do not replace it with a random cap unless the pressure rating matches.
Refill note
Refill slowly, run the tractor until warm with the heater circuit open if fitted, let it cool, then recheck the coolant level. Never remove a hot radiator cap under pressure.
Case IH 4894 Coolant FAQs
How much coolant does a Case IH 4894 take?
The Case IH 4894 takes 18 gal | 68.1 L of coolant. That is about normal for the large ag tractor benchmark shown here, so plan it like a standard drain-and-refill rather than a tiny top-up.
Is the Case IH 4894 coolant capacity normal?
Yes, 18 gal | 68.1 L lands about where you would expect for this tractor category. The main thing is buying enough for a complete refill plus a small top-off amount.
How many coolant jugs do I need for a Case IH 4894?
Do not underestimate this refill. A 18 gal | 68.1 L system needs about 18 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 9 gal of concentrate and 9 gal of distilled water. In metric terms, that is roughly 14 x 5 L containers for a full premix refill.
What coolant should I use in a Case IH 4894?
The listed coolant is 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 Case IH 4894 need?
With the listed 50/50 antifreeze and water mix, a full 18 gal | 68.1 L refill works out to about 9 gal of antifreeze concentrate and 9 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 4894?
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 caseih.com website before draining, flushing or refilling the cooling system.
