Why choose an aluminum housing over the original plastic part?

Aluminum resists cracking and deforming better than many factory plastics, especially under heat cycling and coolant chemistry exposure. That increased strength reduces the chance of coolant leaks and repeat replacements, giving a more durable long-term solution.

• Higher thermal durability than plastic housings
• Improved corrosion resistance for extended service life
• Precision-machined mating surfaces for secure seals
• Less likely to warp or fracture under pressure

What comes in the package and what tools will I need?

The kit comes with one completed aluminum thermostat housing assembly and one water temperature sensor, so you have the essential components for replacement. Basic hand tools and routine cooling-system precautions are all that’s required for most installations.

• Package: 1 thermostat housing assembly and 1 water temperature sensor
• Recommended tools: socket set, torque wrench, screwdrivers, coolant drain pan
• Service notes: drain coolant before removal and replace any old gaskets or hoses as needed
• Installation time: typically 1–2 hours depending on access and experience

Will this part match my vehicle’s OE part numbers?

Yes — this MILIPARTS housing cross-references multiple original equipment numbers so it aligns with factory specifications. Verify the listed OE references against your vehicle’s existing part number or repair manual before ordering.
