Engine Cooling Temperature Regulator ️
This OE-spec coolant control unit keeps your engine at the ideal temperature for power, economy, and long life. It speeds up warm-up after a cold start, stabilizes heat under load, and shields the head, block, and radiator from thermal stress.
How it works ⚙️
Inside is a calibrated wax capsule that expands with heat and drives a valve. When the engine is cold, it stays closed to circulate coolant inside the block for fast warm-up. As temperature rises, it opens progressively, sending flow to the radiator and holding a steady 88–92°C window for consistent performance and smooth heater output.
What happens if it’s broken ⚠️
Stuck closed: rapid overheating, hard upper hose, boiling, faded heater, risk of warped heads and blown gasket. Stuck open: engine runs cold, high fuel use, weak cabin heat, emissions faults (often P0128), sluggish response. A leaking seal causes slow overheating and coolant loss.
Why choose this unit ✅
OE-grade materials, stainless spring, precision wax charge, durable housing, and molded gasket. Direct-fit install, factory calibration, reliable sealing, and stable temperature control mile after mile.
Install tips
Work on a cool engine. Replace gasket, orient jiggle pin up, torque evenly, bleed air, refill 50/50 coolant, and verify opening temp via scan data or IR thermometer.
