Product Overview

Coolant pushed out after a heat cycle needs a safe place to collect instead of coating the engine bay or reaching the ground. A cracked plastic bottle, a custom radiator swap, or a tight engine compartment can make a compact universal reservoir the right solution.

This one-liter aluminum tank can serve as a coolant recovery or overflow bottle when plumbed for the cooling system’s design. Universal does not mean bolt-on: measure the available space, confirm whether the system needs a vented overflow or true recovery arrangement, and select suitable hose and mounting hardware.

Key Features & Performance

  • 1,000 mL capacity for coolant expansion and collection
  • Aluminum construction resists corrosion and engine-bay heat
  • Compact universal shape for custom installations
  • Includes a matching cap
  • Useful for restorations, engine swaps, and replacement of damaged bottles

Common Uses

  • Replacing a cracked or leaking coolant overflow bottle
  • Adding a reservoir to a custom radiator installation
  • Moving an overflow tank to free engine-bay space
  • Catching coolant displaced during normal heat cycles

Technical Specifications

  • Product Type: Universal coolant overflow reservoir
  • Capacity: 1,000 mL / 1 liter
  • Material: Aluminum
  • Cap: Included
  • Fitment: Universal / custom installation
  • Condition: New aftermarket accessory

Installation & Fitment

  • Determine whether the cooling system requires an overflow or recovery configuration
  • Mount the tank upright and away from belts and exhaust heat
  • Use coolant-rated hose and secure clamps
  • Keep the hose path free of kinks and abrasion
  • Pressure-test the cooling system and confirm the radiator cap works correctly

Compatibility Notice

This is a universal or service-tool item, not a guaranteed bolt-on part for every vehicle or machine. Measure the available space and compare the dimensions, connections, capacity, operating limits, and intended system before purchase. Custom mounting, adapters, hose, wiring, or professional setup may be required.

Frequently Asked Questions

Q: Will this bolt into my vehicle’s factory holes? A: Not necessarily. It is a universal tank and may require a custom bracket, hose, or hardware.

Q: Can it fix coolant loss? A: It can replace a leaking reservoir, but overheating, a bad cap, leaks, or combustion-gas problems must be diagnosed separately.

Q: Is the capacity one liter? A: Yes. The listed reservoir capacity is 1,000 mL.

Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
