New Holland T4.105 Coolant FAQs
How much coolant does a New Holland T4.105 take?
The New Holland T4.105 takes 4.1 gal | 15.5 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 4.1 gal | 15.5 L a small coolant capacity for a New Holland T4.105?
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 New Holland T4.105?
This is a manageable refill amount. A 4.1 gal | 15.5 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 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.
How much concentrate and water does a New Holland T4.105 need?
With the listed 50/50 antifreeze and water mix, a full 4.1 gal | 15.5 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 New Holland T4.105?
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.
When should the New Holland T4.105 coolant be changed?
Use whichever limit comes first for the New Holland T4.105: every 1,500 hours or 3 years. Low-hour tractors can still age out on time, because corrosion protection gets weaker even when the coolant still looks clean.
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.
