Mixture note
50/50 antifreeze and water.
Radiator cap note
The radiator cap pressure listed for the New Holland TZ22DA 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.
New Holland TZ22DA Coolant FAQs
How much coolant does a New Holland TZ22DA take?
The New Holland TZ22DA takes 1.5 gal | 5.7 L of coolant. That is on the low side for the compact tractor benchmark, which makes the refill cheaper, but the level still needs to be checked after the first heat cycle.
Is 1.5 gal | 5.7 L a small coolant capacity for a New Holland TZ22DA?
It is low 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 New Holland TZ22DA?
This is a manageable refill amount. A 1.5 gal | 5.7 L system needs about 2 one-gallon containers if you are using premixed coolant. If using concentrate at a 50/50 mix, plan on about 0.8 gal of concentrate and 0.8 gal of distilled water. In metric terms, that is roughly 2 x 5 L containers for a full premix refill.
Can I mix coolant types in a New Holland TZ22DA?
Because the listed coolant is extended-life OAT coolant meeting MAT 3724, 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 New Holland TZ22DA need?
With the listed 50/50 antifreeze and water mix, a full 1.5 gal | 5.7 L refill works out to about 0.8 gal of antifreeze concentrate and 0.8 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 New Holland TZ22DA?
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.
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 newholland.com website before draining, flushing or refilling the cooling system.
