Installation Notes

Professional installation recommended. Cooling system cleanliness is essential.

Cool the engine – Allow the engine to cool completely before beginning work
Drain coolant – Drain the cooling system to a level below the thermostat housing
Remove the thermostat housing – Unbolt and carefully remove the thermostat housing cover
Remove the old thermostat – Note the orientation for correct installation of the new unit
Clean the housing – Clean the housing and mounting surface, removing all old gasket material
Inspect the housing – Check for cracks, corrosion, or warping; replace if necessary
Prepare the new thermostat – Test the new thermostat (optional) in hot water to verify operation
Position the new thermostat – Install with the wax pellet facing the engine (toward the cylinder head)
Align properly – Ensure the jiggle pin/bleed valve is positioned at the highest point (usually 12 o'clock)
Install the new gasket – Place the new gasket or O-ring on the housing or thermostat as required
Reinstall the housing cover – Bolt the thermostat housing cover back into place
Tighten to specification – Torque the housing bolts to manufacturer specification
Refill coolant – Refill the cooling system with the correct mixture and type of coolant
Bleed air from the system – Use the jiggle pin and/or bleed valves to remove air from the system
Check for leaks – Start the engine and inspect for any coolant leakage around the housing
Verify operation – Allow the engine to reach operating temperature and confirm the thermostat opens

Quality Control

Temperature Calibration: Opening and closing temperatures verified against OE specifications
Dimensional Inspection: Housing diameter, height, and mounting features verified against OEM tolerances
Spring Tension Testing: Spring force measured to ensure correct valve operation
Leakage Testing: Sealing performance verified when closed
Stroke Verification: Valve lift (opening distance) measured to ensure adequate coolant flow
Material Verification: Confirms housing and internal components meet OE specifications
Jiggle Pin Function: Bleed valve operation verified
Visual Inspection: 100% checked for housing defects, corrosion, or damage
Packaged Safely: Protected and securely packaged to prevent damage during transit
