Dayco Expansion Tank (supplied with cap)
- The expansion tank is an essential component of the cooling system.
- It is always under pressure and is responsible for releasing pressure from the hot coolant.
- The pressure cap is located on the expansion tank itself, not on the radiator.
- Designed to be at the highest point in the cooling system, the expansion tank allows for continuous cycling of coolant.
- The hot coolant fills the top half of the tank, creating a force that pushes the coolant back into the system.
- Over time, expansion tanks can become discoloured, brittle, contaminated with sludge, or even break.
- Immediate replacement is necessary to ensure the cooling system operates effectively.
- Dayco Expansion Tanks are manufactured to OE specifications.
- They are specifically designed for make and model compatibility.
- Comes with a 2-year warranty or 40,000km, whichever comes first.
- Includes expansion tank and cap.

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): For products listed to suit a specific vehicle, our fitment data 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. It is the buyer's responsibility to confirm the part suits their vehicle before purchasing. If you have any doubt, please message us with your vehicle's registration number and state (preferred), or full VIN/build details, and we'll do our best to confirm before you buy.
