Change Coolant in 3 Simple Steps

To change your coolant in three simple steps, first drain the old coolant by opening the radiator drain plug and collecting it safely. Next, flush the cooling system with a radiator flush solution, run the engine briefly, then drain and rinse with clean water. Finally, refill the system with the correct coolant mixture, start the engine to circulate fluid, and check for leaks. Following these essentials guarantees your engine stays cool; keep going to discover helpful tips for a smooth process.

Drain the Old Coolant

Before you add new coolant, you need to drain the old fluid completely. Start by verifying your engine is cool to avoid burns.

Locate the radiator drain plug or petcock at the bottom of the radiator. Place a suitable container underneath to catch the draining coolant.

Open the drain plug carefully and let the fluid flow out entirely. Don’t forget to open the radiator cap or coolant reservoir cap to allow air in, which speeds up drainage.

Once the flow slows to a drip, close the drain plug securely.

Dispose of the old coolant properly, as it’s toxic and harmful to the environment.

Draining the old coolant fully prevents contamination and ensures your cooling system functions efficiently with fresh fluid.

Flush the Cooling System

Once you’ve drained the old coolant, flushing the cooling system removes any remaining debris and contaminants that could clog or damage your engine.

Start by closing the drain valve or removing the plug if necessary. Next, fill the radiator with a radiator flush solution mixed with water, following the product instructions.

Run the engine with the heater on high for about 10 to 15 minutes to circulate the flush through the entire system.

Afterward, turn off the engine and allow it to cool completely. Then, drain the flush solution from the radiator, making sure to collect it properly for disposal.

Finally, rinse the system with clean water to guarantee all residues are gone before you move to the next step.

Refill With New Coolant

After thoroughly flushing the cooling system and rinsing out all residues, you’re ready to refill it with new coolant. Start by choosing the right coolant type for your vehicle, as specified in the owner’s manual.

Next, mix the coolant with distilled water if it’s a concentrate, usually at a 50/50 ratio.

Follow these steps to refill:

1. Slowly pour the coolant into the radiator or reservoir until it reaches the recommended level.
2. Replace the radiator cap securely to prevent leaks.
3. Start the engine and let it run with the heater on to circulate the coolant and remove air pockets.

Check for leaks and monitor the coolant level, topping off if necessary.
