Our take on the Universal Coolant Radiator Tank Overflow Tank Reservoir Expansion 1L/2L

This is a universal 2L aluminum coolant overflow and expansion tank meant to replace a cracked or missing plastic reservoir on most cars. The aluminum body and O-ring gasket suit it to custom builds and older vehicles where factory plastic tanks are brittle or discontinued. It is a generic part, not a vehicle-specific OEM unit, so fitment depends on hose size and mounting space. The 36 mm bore and roughly 10 x 6 x 4 inch package size are the numbers to check against your engine bay before buying.

Best for
Owners of older cars with cracked or discontinued plastic tanks
Custom and swapped builds that need a generic reservoir
Drivers who want an aluminum tank instead of plastic
Budget repairs where an OEM tank is expensive or unavailable
Pros
  • Aluminum body resists heat and cracking better than aging plastic
  • 2L capacity covers most stock overflow needs
  • O-ring gasket seals the cap without sealant

  • Light package weight makes shipping and install simple
Cons
  • No vehicle-specific mounting brackets or hose routing
  • 36 mm bore may not match every stock hose or cap
  • Generic part, so build quality varies between sellers

Questions and answers

Will this fit my car?
Only if your car's overflow hose and cap match the 36 mm bore and you have room for a roughly 10 x 6 x 4 inch tank. It is a universal part, so measure your engine bay and existing hose before ordering.
Is it a direct replacement for a stock plastic tank?
Not directly. You will likely need to adapt hose routing and make your own mounting, since no vehicle-specific brackets are included.
Does it come with a cap?
The listed contents are the coolant radiator tank only. Confirm with the seller whether a cap and O-ring are included before you buy.
Can it handle a pressurized cooling system?
The aluminum body and O-ring gasket are built for coolant service, but check the seller's pressure rating. A universal tank may not hold the same pressure as your factory cap.
Is 2L enough for my engine?
For most cars, a 2L overflow tank is in the normal range. Large trucks or heavily modified engines may need more volume.
When is it cheapest?
Generic tanks like this usually cost least from marketplace sellers and during seasonal auto parts sales. Compare listings, since prices for the same part vary widely.
