Dayco Expansion Tank
- The expansion tank is an essential component of the cooling system.
- It is always under pressure and has the pressure cap located on it.
- The tank is typically positioned at the highest point in the cooling system.
- Coolant is continuously cycled through the tank.
- The hot coolant releases pressure, filling the top half of the tank.
- This pressure acts as a force to push the coolant back into the system.
- Tanks can become discoloured, brittle, contaminated with sludge, or even break.
- Immediate replacement is necessary for effective operation of the cooling system.
- Dayco Expansion Tanks are made to OE specifications.
- They are designed for specific make and model compatibility.
- Comes with a 2-year or 40,000km warranty.

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.
