Dayco Expansion Tank
The expansion tank is an essential component of your vehicle's cooling system. Unlike the radiator, the expansion tank is always under pressure and houses the pressure cap. It is typically positioned at the highest point in the cooling system, allowing the coolant to continuously cycle through it.
Over time, expansion tanks can become discoloured, brittle, contaminated with sludge, or even break. When this happens, immediate replacement is necessary to ensure the cooling system operates effectively.
Key Features:
- Made to OE specifications
- Designed for specific make and model
- Ensures proper pressure regulation
- High-quality construction for durability
- 2 years 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.
