If you have ever experienced an issue in which your engine overheats and also is leaking coolant, don’t sweat it. This is a common problem but it doesn’t have to be enough cause for worry. If you take action quickly, there’s a chance of saving your car from serious damage.
What is Coolant Overflow Tank?
Coolant overflow tanks are typically cylindrical and mounted on the side of a radiator. The tank holds the coolant that is circulated through the engine to keep it from overheating. Coolant overflow tanks can also contain a system to remove moisture from the air.
One of the most common problems with coolant overflow tanks is buildup of sediment, dirt, and debris. This canworn down the metal surface of the tank, which can lead to leaks and even a complete failure of the tank. To clean an overflow tank, start by soaking it in a cleaning solution for several hours. Clean all surfaces using a degreaser and a soft brush. Pour fresh coolant into the tank, and rinse it out well.
How to Clean the Coolant Overflow Tank
One of the most common causes of a coolant overflow is blockedcoolant filters. Blocked filters can also be caused by debris buildup, chunks of metal, and other objects in the coolant. Regardless of the cause, a blocked filter will result in decreased cooling and may even lead to a blown head gasket.
To clear a blocked filter:
1) Remove the cap from the top of the coolant overflow tank.
2) Use a tube wrench to remove the clamp that holds the filter in place. Carefully remove the filter. If there is visible debris on it, use a toothbrush or broom to clean it off before reinstalling it.
3) Pour enough fresh coolant into the tank to cover the filter. Gently push down on the filter until it is submerged.
4) Replace the clamp and cap and turn on the engine. The pressure from the engine should force any debris out of the filter and into the coolant. Check for blockages after 24 hours and/or if there is still an odor or decrease in cooling ability. If problems persist, contact your local dealership or repair shop.
