3375252 Coolant Tank provides auxiliary coolant storage and level management for B2B excavator parts repair, replacement, and wholesale sourcing.
The 3375252 Coolant Tank YNF17841 is used as an auxiliary reservoir within a compatible construction machinery engine cooling system. Coolant volume changes as the engine heats and cools during operation, and additional fluid can be stored within the reservoir according to the cooling-system design.
This component may also be referred to as a coolant reservoir, sub tank, expansion tank, or radiator overflow tank. It should be distinguished from the main radiator because its primary role is coolant storage, recovery, and level management rather than direct heat dissipation.
For B2B buyers, the 3375252 coolant reservoir should be checked by reference number, overall tank shape, mounting points, hose connections, cap position, and existing-part photos before quantity purchasing. Accurate confirmation helps wholesalers reduce incorrect stock, installation mismatch, customer returns, and unnecessary international freight.
