RADIATOR FLUSH

Radiator Flush in 5 Easy Steps

Why do it?
A radiator keeps your engine cool. If you don’t flush it, rust and dirt can block the system and cause overheating. Flush it every 5 years or 100,000 miles.

Step 1: Locate the Radiator

Open the hood and find the radiator with a cap labeled “coolant.”

Step 2: Drain Old Coolant

Open the drain valve or remove the lower hose and let the old coolant flow into a drain pan.

Step 3: Flush with Distilled Water

Close the valve, fill the radiator with distilled water, run the engine 10–15 minutes, then drain again.

Step 4: Add New Coolant

Pour a 50/50 mix of coolant and distilled water into the radiator. Fill the overflow tank to the service line.

Step 5: Top Off

Shut off the engine and add a little more coolant until the overflow tank is about 2 inches below the line.

✔ Your cooling system is now clean and ready for another 100,000 miles.
