Good To Know

Q: Do I need to replace the thermostat and outlet together? A: On this 1.8L design the thermostat is housed inside the outlet assembly, so the two are serviced as one unit. If either the thermostat or the housing is failing, replacing the whole assembly handles both at once.

Q: Should I bleed the cooling system after installing it? A: Yes, trapped air can cause erratic temperature readings and poor heater performance. Refill slowly and run the engine with the bleed procedure for your model until coolant circulates steadily.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
