Our take on the Baguer Aluminum Coolant Overflow Tank 2.5L Radiator Expansion Reservoir

The Baguer is a universal aluminum coolant overflow and expansion reservoir with a 2.5 L (84.5 fl oz) capacity and a 1.3 bar pressure-relief cap. The aluminum body resists cracking and heat better than the plastic tanks it typically replaces, and the cap holds system pressure to help prevent overheating. It suits drivers replacing a cracked or yellowed factory tank, or anyone building a custom cooling setup who wants a metal reservoir. Fitment is generic rather than vehicle-specific, so brackets and hose routing are up to the installer.

Questions and answers

Will this fit my car?
It is a universal tank, not a vehicle-specific one. Check the 15 x 10 x 16.2 cm body size and your hose and mounting points before buying.
Is the cap a real pressure cap?
Yes. It is rated at 1.3 bar, which relieves pressure above that level. Confirm your cooling system's specified cap rating matches.
Does it come with mounting hardware?
The package lists only the storage tank. Brackets, hoses and clamps are not included, so plan your own mounting.
Is it a direct replacement for a factory plastic tank?
Not directly. It has no OEM number and generic fittings, so expect to adapt hoses and brackets.
What is the capacity?
2.5 L, or 84.5 fl oz, which is larger than many stock overflow tanks.
Where is the Baguer Aluminum Coolant Overflow Tank 2.5L Radiator Expansion Reservoir cheapest?
At Walmart, for $56.50, as of our latest check.
