April, 2009 Dayco, the leading brand of automotive power transmission and cooling system components in the Australian and New Zealand aftermarket has released a new premium quality range of Heater Tap Control Valves.

Heater control valves regulate the flow of engine coolant to the vehicle’s heater core. In the off position, the heater control valve blocks coolant flow to the heater core when no heating is required and the reverse is applied to activate interior heating. In late model vehicles the heater valve can be activated by vacuum control or in older models by cable.

Common heater valve failures include leakage, blocking and cracking due to the fact that most late model heater control valves are made of polymer. Often the cracking occurs when heater hoses are removed.

Dayco has released a premium quality aftermarket replacement heater control valve program for fitment to popular local and imported vehicles. Initial Dayco replacement heater control valve applications include the following:

Holden Barina, Astra & Vectra
Holden VN - VY 6 cyl.
Holden VZ 6cyl.
Holden HQ - HZ Torana 6 cyl.
Ford EA - AU V8
Ford EA - AU 6cyl.
Ford XD - XF 6cyl.
Ford XA - XC 6 cyl.
Universal Fitment Model (DHV4008)  

All Dayco heater control valves have been manufactured to meet or exceed OEM standards. These new additions to Dayco’s extensive aftermarket product range share the total quality characteristics that are synonymous with the well trusted Dayco name.
