Detailed Description

Motorad’s Kit product line focuses on complete cooling-system service parts built to OE specifications. The 5158KTFS thermostat housing assembly uses a copper case and wax compound to react quickly to coolant temperature changes, helping the engine reach and maintain the correct operating range. For Honda Civic owners servicing 1996-2000 models, this assembly supports accurate coolant flow control and a proper housing-to-engine seal.

This part cross-references 95158KTFS for the same application. Use 5158KTFS when replacing a thermostat housing assembly on a 1996-2000 Honda Civic and when OE-specified 170°F temperature control is required.

Common Repair Uses

• Coolant leaks at the thermostat housing
• Erratic engine temperature readings
• Overheating caused by a sticking thermostat
• Slow warm-up from a thermostat that no longer regulates correctly
• Service replacement for a worn Honda Civic coolant outlet assembly

Installation Notes and Tips

Confirm the OE-specified 170°F temperature before installation. Inspect the mating surfaces, coolant passages, and hose connections for corrosion or residue before assembly. Because the gasket or seal is not listed as included separately, verify the seal condition during service and replace any damaged coolant hoses or clamps as needed. Bleed trapped air from the cooling system after installation to help prevent temperature fluctuations.
