Engine displacement
14.2 L | 868 cu in
Capacity note
For the Case IH 4994, the listed cooling system capacity is 22 gal | 83.3 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 4994 is 13.1 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 4994 Coolant FAQs
How much coolant does a Case IH 4994 take?
The Case IH 4994 takes 22 gal | 83.3 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 22 gal | 83.3 L a lot of coolant for a Case IH 4994?
Yes. For this tractor category, 22 gal | 83.3 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 Case IH 4994?
Do not underestimate this refill. A 22 gal | 83.3 L system needs about 22 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 11 gal of concentrate and 11 gal of distilled water. In metric terms, that is roughly 17 x 5 L containers for a full premix refill.
What coolant should I use in a Case IH 4994?
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 4994 need?
With the listed 50/50 antifreeze and water mix, a full 22 gal | 83.3 L refill works out to about 11 gal of antifreeze concentrate and 11 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 4994?
The listed cap pressure is 13.1 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.
