How to Refill the Coolant without a Bleed Tool

Posted on: November 25th, 2015 by Gene Hannon

Draining and refilling the coolant is one of the easier maintenance tasks you can do on most vehicles. In addition to saving money, doing your own maintenance is a way to monitor the health of your vehicle.

Coolant loses effectiveness over time, so it’s important to periodically drain and refill the cooling system. In addition, as coolant becomes dirty, and rust and particles can eventually degrade cooling system components, such as the engine and water pump.

If you drain the system and then pour coolant in, there is still air trapped within the hoses and components that hold coolant. That air must be removed. You’ll need to bleed out the air and then top off the coolant to the proper level.

Some car manufacturer refill procedures use a special tool that automatically fills the cooling system and bleeds any excess air. In most cases, if you don’t have the special tool, you can still fill the cooling system and bleed it manually. In rare cases, vehicles need to be serviced with specialized cooling system equipment, due to the complexity of the cooling system. Air will become trapped in the cooling system, and cause the engine to overheat! Check the service information before you attempt the procedure.
