Buy Water Pump, TJ, KJ (2.4L) (4694307AF)

The Water Pump (Part Number 4694307AF) is a crucial component in the cooling

system of many vehicles equipped hwith the 2.4‑liter inline 4‑cylinder engine, notably

certain Jeep Wrangler (TJ) Water Pump 4694307AF and Jeep Liberty (KJ) Water

Pump 4694307AF applications. This part is designedh to circulate engine coolant

throughout the engine block, cylinder head, radiator, and heater core, ensuring that operating

temperatures remain within a safe range and preventing overheating.

Mechanically driven off the engine’s accessory belt or timing belt system, the water pump

houses a rotating impeller that draws coolant from the radiator and pushes it through the

engine’s internal passages. As the engine operates, heat generated by combustion and friction

must be carried away; the water pump makes this possible by maintaining continuous flow of

coolant. Without a properly functioning water pump, coolant would stagnate, the engine

would rapidly overheat, and severe damage such as warped heads or blown gaskets could occur

The 4694307AF version is a direct replacement

The 4694307AF version is a direct replacement for earlier water pump part numbers like

4694307AB, 4694307AC, and 4694307AE — meaning it supersedes those older components

while fitting the same mounting points and sealing surfaces. It typically includes the pump

housing, impeller, and necessary seals or gaskets to ensure a leak‑free fit once installed. As an

OEM‑designated part made to meet original manufacturer standards, it offers reliable

performance and compatibility. In terms of fitment, this water pump is most commonly

associated with Jeep models equipped with the 2.4 L engine from the early to

mid‑2000s, such as the TJ Wrangler (2003‑2006) and KJ Liberty (2002‑2005). However, the

4694307AF designation may also appear in broader Mopar 2.4 L engine applications across

other Chrysler‑ and Dodge‑branded vehicles. Always verify specific vehicle fitment before purchase.

When replacing the water pump, technicians typically drain the cooling system, remove the

accessory drive belt and any obstructions (such as fan shrouds), and then unbolt the old

pump. New gaskets or seals are essential to prevent leaks. After installation, the cooling

system must be refilled and properly bled of air to maintain optimal performance. A worn or

failing water pump can exhibit signs like coolant leaks at the weep hole, overheating, or reduced heater performance, signaling replacement is needed.
