Case IH C70 Extra Coolant Notes
Engine horsepower
73 hp | 54.4 kW
Engine displacement
4.2 L | 258 cu in
Capacity note
For the Case IH C70, the listed cooling system capacity is 4 gal | 15.1 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 C70 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 C70 Coolant FAQs
How much coolant does a Case IH C70 take?
The Case IH C70 takes 4 gal | 15.1 L of coolant. That is below the average utility tractor benchmark, so it is not a huge coolant job, but you still want spare premix for topping off.
Is 4 gal | 15.1 L a small coolant capacity for a Case IH C70?
It is below average compared with the benchmark on this page. That makes the job cheaper, but it does not make coolant choice or bleeding less important.
How many coolant jugs do I need for a Case IH C70?
This is a manageable refill amount. A 4 gal | 15.1 L system needs about 4 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 2 gal of concentrate and 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 C70?
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 C70 need?
With the listed 50/50 antifreeze and water mix, a full 4 gal | 15.1 L refill works out to about 2 gal of antifreeze concentrate and 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 C70?
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.
