Cooling-system maintenance for hard-working 4x4s

A serviceable water pump is essential for coolant circulation when an engine is climbing, towing, crawling at low speed or travelling in hot conditions. Check the rest of the cooling system and replace worn or leaking components as part of the repair.

Fitment check: Confirm WPT-109 against the VIN, engine code, chassis/series, build date and the pump removed from the vehicle before ordering. Only the 4x4 applications listed above are included where fitment details are available. Professional installation is recommended.
