Detailed Product Description

This engine coolant thermostat housing assembly is crafted from a combination of aluminum, steel, and copper, materials chosen for their strength and thermal conductivity. The silver finish helps resist corrosion, extending the part's service life. The thermostat is calibrated to open at 170 degrees Fahrenheit, ensuring optimal engine temperature regulation. The inclusion of a bleeder hole allows trapped air to escape, preventing overheating and maintaining efficient coolant circulation. With two outlet ports and a bypass system designed to Nissan GT-R specifications, this thermostat housing assembly supports proper coolant flow and engine performance.

Common Applications and Problem Resolution

• Replacement for faulty or leaking thermostat housings in Nissan GT-R vehicles
• Solves engine overheating issues caused by thermostat failure
• Addresses coolant leaks due to cracked or corroded housing assemblies
• Improves coolant flow with integrated bypass design
• Prevents air pockets in the cooling system with built-in bleeder hole

Installation Notes and Tips

Installation requires removal of the existing thermostat housing; note that mounting hardware and gasket or seal are not included and must be sourced separately. Ensure the cooling system is properly drained before installation. The three bolt holes align with Nissan GT-R mounting points for secure fitment.
