Coolant is an important regulator of engine temperatures. Coolant is a mixture of glycol and water. The chemical solution is able to withstand temperatures that would boil pure water, cooling an engine when its running; yet it also resists freezing, remaining a liquid when the engine is off overnight in severely freezing weather. You can purchase automotive coolant at any auto parts shop and most general retailers. Replacing the coolant in a 2005 Mini Cooper is a simple process. Check your Mini's coolant levels regularly, and add when necessary.

  1. 1

    Park the Mini Cooper on a level surface and turn off the engine. Pull the hood latch inside the cabin, then get out an open the Mini Cooper's bonnet. Let the engine cool before continuing.

  2. 2

    Loosen the coolant tank's cap slightly. The coolant tank is located behind the radiator. Do not remove the cap, just loosen it so excess pressure can escape. Wait a couple of minutes, then remove the cap completely.

  3. 3

    Check the coolant level by seeing where the liquid fills the tank. If the liquid is below the MIN line, you'll need to add coolant.

  4. 4

    Add coolant to the coolant tank until the coolant level reaches the MAX line. Do not go fill the tank with coolant past the MAX line.

  5. 5

    Place the cap back onto the coolant tank and tighten it firmly. Close the bonnet of the vehicle.

Tips and warnings

  • Do not add coolant when the engine is hot, as escaping coolant can cause burns.
