|---|---|
| Engine displacement | 2.2 L | 134 cu in |
| Capacity note | For the Case IH Farmall DX55, the listed cooling system capacity is 4.5 gal | 17 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 Farmall DX55 is 10 psi | 70 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 Farmall DX55 Coolant FAQs
How much coolant does a Case IH Farmall DX55 take?
The Case IH Farmall DX55 takes 4.5 gal | 17 L of coolant. That is about normal for the utility tractor benchmark shown here, so plan it like a standard drain-and-refill rather than a tiny top-up.
Is the Case IH Farmall DX55 coolant capacity normal?
Yes, 4.5 gal | 17 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 Farmall DX55?
This is a manageable refill amount. A 4.5 gal | 17 L system needs about 5 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 2.2 gal of concentrate and 2.2 gal of distilled water. In metric terms, that is roughly 4 x 5 L containers for a full premix refill.
Can I mix coolant types in a Case IH Farmall DX55?
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 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 Farmall DX55 need?
With the listed 50/50 antifreeze and water mix, a full 4.5 gal | 17 L refill works out to about 2.2 gal of antifreeze concentrate and 2.2 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 Case IH Farmall DX55?
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.
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.
