How does the aluminum housing help compared with the original plastic unit?

Aluminum offers improved thermal stability and resistance to long-term deformation under heat cycles compared with molded plastic housings. That makes the FRONEZER housing less likely to warp, crack, or develop coolant leaks during engine operation.

• Aluminum construction reduces warpage and maintains a consistent sealing surface.
• Built-in corrosion resistance for longer service life in coolant environments.
• Neoprene O-ring helps ensure a tight, leak-resistant seal at the junction.
• Pre-installed sensor and bolts simplify replacement and reduce installation errors.

What’s included in the kit and how easy is installation?

The FRONEZER kit arrives complete so you won’t need to hunt down separate parts. The thermostat housing comes with the temperature sensor, gasket, and mounting bolts already fitted, which shortens bench time and lowers the chance of losing small components during the swap.

• Complete assembly: aluminum housing with sensor, gasket, and bolts pre-installed.
• Plug-and-play sensor mounting aligns with factory wiring harness and socket.
• Direct bolt pattern and mating surfaces match OEM locations for straightforward fitment.
• Installation typically requires standard hand tools and coolant draining, then refill and bleed.

Does FRONEZER back this part with a warranty?

Yes—this water outlet kit is covered by a two-year warranty that reflects the brand’s confidence in manufacturing and testing processes. If you encounter a defect or fitment issue within the warranty period, FRONEZER provides customer support to resolve the problem.

• Two-year limited warranty against manufacturing defects.
