With the drainage screw exposed and a container in place, you’re ready to start removing the old coolant from your radiator.

First, make certain the engine is completely cool to avoid burns.

If there’s a plastic shield blocking access, use a 10 mm socket to remove it carefully.

Then, slowly unscrew the drainage plug at the bottom of the radiator and let the coolant drain fully into your container.

Pay close attention to the fluid’s color and look for any signs of corrosion.

This could indicate issues within the cooling system.

Once the radiator empties, securely tighten the drainage screw back in place to prevent leaks.

This step guarantees your cooling system is ready for the next phase of radiator cleaning.

Applying the Pristone Cooling System Cleaner

Once you’ve drained the old coolant, pour the Pristone cooling system cleaner into your radiator to get the cleaning started.

Next, turn on your vehicle and set the heater to maximum heat. Let the engine run for 10-12 minutes so the cleaner can circulate thoroughly throughout the cooling system.

While the engine runs, keep a close eye on the temperature gauge to guarantee the system stays within a safe operating range and is functioning properly.

After this cleaning cycle, turn off the engine and drain the radiator again.

Check the drained fluid for any remaining contaminants or discoloration, which indicates how much buildup was removed.

This step prepares your radiator for the next phase of cleaning, guaranteeing your cooling system is well-maintained and ready for flushing.

Flushing the Radiator With Distilled Water

Although you’ve already applied the Pristone cooling system cleaner, you still need to flush the radiator with distilled water to remove any remaining contaminants.

Start by pouring distilled water into the radiator. Then, run your vehicle for 10-12 minutes with the heater set on maximum heat.
