Our take on the Unique Bargains 1L Aluminium Coolant Expansion Reservoir Tank with Cap Universal Polished

A universal 1L aluminum coolant expansion and recovery tank with a knurled, gasket-sealed cap, a magnetic drain plug and a level hose. The polished aluminum body resists heat and corrosion and gives coolant room to expand, which helps keep air and steam out of the cooling system. It suits drivers replacing a cracked or leaking plastic reservoir or adding a recovery tank to a project car. Against stock plastic tanks it is sturdier and easier to drain, but it is a generic fit, so brackets and hose routing may need adapting.

About the Unique Bargains 1L Aluminium Coolant Expansion Reservoir Tank with Cap Universal Polished

This is a universal 1L coolant expansion reservoir tank made of corrosion-resistant aluminum alloy with a polished silver-tone finish. It gives the coolant room to expand and helps remove stagnant air and steam from the engine. This helps avoid coolant expansion and ruptured radiator tubes.

A knurled cap with an inner rubber gasket seals the tank against coolant leaks. A magnetic drain plug at the base allows quick draining and easy cleaning. The aluminum alloy resists high temperatures and seals tightly.

To install, turn off and cool down the car, then remove the bolts and the old reservoir. Let the remaining coolant drain into a pan. Fit the new tank, reconnect the coolant hose to the radiator and tighten the clamp. Then check that it works properly. This is a non-OEM accessory, so check your car model before purchasing.

Questions and answers

Will this fit my car?
It is a universal tank, not a vehicle-specific one. Check the 13.1 x 11.7 x 8.4 cm body size and your hose and mounting points before buying.
What is included?
One aluminum expansion tank with cap, magnetic drain plug and level hose. Mounting brackets and hardware are not listed.
How much coolant does it hold?
1 liter. That is enough expansion space for most small and mid-size engines, but check your cooling system's needs.
Is it better than the stock plastic tank?
Aluminum resists heat and cracking better than plastic and adds a drain plug. The trade-off is that it is generic, so fitting takes more work.
Can I use it as an overflow tank only?
Yes. It works as a recovery tank that catches expanding coolant and returns it as the engine cools.
Where is the Unique Bargains 1L Aluminium Coolant Expansion Reservoir Tank with Cap Universal Polished cheapest?
At Woolcan, for $10.00, 62% under what the other stores charge, as of our latest check.
Where can I buy the Unique Bargains 1L Aluminium Coolant Expansion Reservoir Tank with Cap Universal Polished?
