Dayco Heater Tap
The Dayco Heater Tap is a 2 port valve designed to regulate the flow of coolant to the heater core. It is essential for controlling the heating inside your vehicle.
- Type: 2 port
- Outside Diameter: 16mm
The Heater Control Valve is responsible for blocking coolant flow to the heater core when heating is not required, and allowing flow when heating is needed. It can be activated by vacuum control in late model vehicles and cable in earlier models.
Common failures of the Heater Control Valve include leakage, blocking, and cracking when removing heater hoses, especially in late model valves made of polymer.

Packaging: Manufacturers periodically update their packaging and labelling. You may receive the current or a previous design — the product, formulation and part number are unchanged.
Fitment (vehicle-specific products): Vehicle fitment is based on manufacturer and supplier catalogue data and is kept as accurate as possible, but vehicle catalogues are not perfect. Some models had more than one part fitted depending on build date, engine, or component size/variant, and parts on older vehicles may have been replaced with non-original or different-style components.
Before you buy, compare the product images with the part currently fitted to your vehicle — check shape, size, connectors and mounting points. If the part on your vehicle looks different, please contact us before purchasing. It is the buyer's responsibility to confirm the part suits their vehicle before purchasing.
Not sure? Message us with your vehicle's registration number and state (preferred), or full VIN/build details, and we'll do our best to confirm fitment before you buy.
Parts returned because they do not suit the vehicle, where the listing matches the manufacturer's catalogue, are treated as a change of mind and must be unused, uninstalled and in original packaging. Nothing in this notice affects your rights under the Australian Consumer Law.
