What parts are included and how do they improve reliability?

The kit includes the water pump, thermostat housing, and thermostat, covering the primary failure points of the coolant circulation system. Each component uses upgraded coatings and original-style rubber to resist corrosion and leaks.

• One water pump built from thickened steel with multi-layer corrosion protection
• Thermostat housing pre-installed to eliminate mismatched parts during installation
• OE-formula rubber gaskets sourced for durable sealing and minimal coolant seepage

How does installation affect cooling performance?

Replacing an older pump and thermostat restores proper coolant flow and accurate thermostat operation, helping the engine reach and hold its designed temperature range more consistently. Proper installation can reduce overheating events and prevent future component damage.

• Direct-fit design aligns with factory mounting points for straightforward replacement
• Thermostat calibrated to open at the specified engine temperature for correct warm-up
• Quality seals reduce the chance of external leaks after installation

What quality assurances and support does YWPXMY provide?

YWPXMY constructs the metal components with heavy-gauge steel, applies triple-layer electrophoresis and baking paint for corrosion resistance, and uses original rubber compounds to match OEM performance. The kit is backed by a one-year warranty and responsive customer service.

• Triple-layer protective coating for extended component life
• Original-equivalent rubber parts for consistent sealing performance
• One-year warranty and 24/7 customer support for post-install questions

Who is this for: This kit is aimed at owners and independent mechanics working on 3.6L Chrysler-family vehicles who need a reliable, complete replacement set—ideal for cars showing coolant leaks, overheating, poor heater output, or when performing preventative maintenance.
