Dayco Expansion Tank
The expansion tank is an essential component of the cooling system in your vehicle. It is designed to handle the pressure and store excess coolant. Unlike the radiator, the expansion tank houses the pressure cap and is strategically positioned at the highest point in the system.
Key Features:
- Made to OE specifications for reliable performance
- Specifically designed for make/model compatibility
- Ensures effective operation of the cooling system
- Prevents coolant loss and overheating
- Durable construction for long-lasting use
- Resistant to discoloration, brittleness, and sludge contamination
Don't compromise the performance of your vehicle's cooling system. Replace your old or damaged expansion tank with a high-quality DAYCO Expansion Tank. With a warranty of 2 years or 40,000km, you can trust its durability and reliability.

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.
