What does the YBDDZH kit include and how does it match original parts?

• Complete water pump assembly sized to OEM mounting and pulley alignment
• Thermostat designed to open at the vehicle’s specified temperature range
• Gaskets and seals to prevent coolant leakage at mating surfaces
• Manufacturing and inspection aimed at OE compatibility and interchange

How do I confirm this kit fits my RAM, Grand Cherokee, or Dakota?

Fitment depends on engine displacement and model year. The kit lists a broad set of compatible vehicles; use the seller’s partfinder or cross-check the OE reference numbers to be certain the mounting pattern and connections match your vehicle.

• Compatible with many 3.7L V6 and 4.7L V8 engines from 2000–2013

What should I expect during installation and maintenance?

Installation follows factory procedures for draining coolant, removing the accessory drive where necessary, and replacing the pump and thermostat with new gaskets. Proper torque, clean mating surfaces, and fresh coolant are important to avoid leaks and premature failure.

• Drain and dispose of coolant safely, then remove old pump and thermostat
• Clean the mounting surfaces and use supplied or equivalent gaskets
• Tighten fasteners to manufacturer torque specs and refill with recommended coolant
• Pressure-test the cooling system and check for leaks after installation
