Good To Know

Q: Will this valve fix a heater that blows cold? A: If your heater core is not receiving hot coolant, a failed valve is a common cause, and replacing it often restores cabin heat.

Q: Do I need to drain the cooling system? A: Yes, coolant should be drained or clamped off before removal to limit spillage, then topped up and bled after installation.

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