How does the aluminum housing compare to the original plastic part?

Aluminum brings greater dimensional stability under heat cycling than many factory plastics, reducing the chance of distortion that leads to leaks. The supplied neoprene O-ring and quality machining help maintain a tight seal at the coolant passage and sensor aperture.

• Cast aluminum reduces warpage vs. plastic housings
• Precision bore for improved sensor seating and sealing
• Neoprene O-ring enhances leak resistance at the mating surface

What should I expect during installation and maintenance?

Installation follows the original mounting points and coolant hose connections; the sensor and bolts come pre-installed to speed the swap. After fitting, refill and bleed the cooling system per vehicle service procedures and inspect for leaks during the first drive cycles.

• Bolts and sensor pre-installed for quicker replacement
• Follow OEM cooling system refill and bleed steps after install
• Inspect hose clamps and mating surfaces for leaks after warm-up
