Removing radiator coolant involves draining the old fluid from your vehicle's cooling system. Here's how to do it:
-
Locate the Drain Plug: The drain plug is typically found at the bottom corner of your radiator. It might be plastic or metal.
-
Prepare a Collection Pan: Place a drain pan directly underneath the drain plug to catch the old coolant as it empties from the radiator. Coolant is toxic, so avoid spilling it.
-
Loosen the Drain Plug: Carefully loosen the drain plug. Most drain plugs can be opened by hand or with a wrench. Be prepared for coolant to start flowing as soon as you loosen it.
-
Allow Coolant to Drain Completely: Let the coolant drain completely into the pan. This may take several minutes. To speed up the process, you can remove the radiator cap (but only if the engine is completely cool!). Removing the cap allows air to enter the system and helps the coolant drain more freely.
Important Considerations:
- Safety First: Always ensure the engine is completely cool before attempting to remove the radiator cap or drain the coolant. Hot coolant can cause severe burns. Wear gloves and eye protection to avoid direct contact with the coolant.
- Environmental Responsibility: Dispose of used coolant properly. Most auto parts stores and recycling centers accept used coolant for recycling. Never pour coolant down drains or onto the ground.
- Flushing the System (Optional): While you are draining the system, consider flushing the radiator with a radiator flush product to remove any built-up sediment or rust. Follow the instructions on the flush product carefully.
- Replacing the Coolant: After draining (and flushing, if you choose), ensure the drain plug is tightened and refill the radiator with the correct type and mixture of coolant specified in your vehicle's owner's manual. Often, this is a 50/50 mix of coolant concentrate and distilled water.
- Bleeding the System: After refilling, you may need to "bleed" the cooling system to remove any trapped air. Consult your vehicle's service manual for specific instructions on how to do this, as it varies by vehicle model.
