Questions about this item
Will the Four Seasons 74828 transparent heater valve fit the existing hoses on my older vehicle?
The valve is designed as a direct replacement for the original equipment heater control valve; match the inlet and outlet diameters on your current hoses to the valve ports before installation.
How can I verify the 74828 valve is operating correctly once installed?
With the engine at operating temperature, turn the climate control to hot and feel both heater hoses — they should be equally warm, confirming coolant flows through the valve.
What comes in the box with the Four Seasons 74828 and what must I supply?
The package contains the transparent heater valve only; you will need to provide compatible heater hose, clamps and coolant for the installation.
