Instructions

1. Open the hood and inspect the water pump and gasket seal for signs of leakage. The water pump is behind the radiator and attached to the engine. The gasket seal securely connects the water pump to the engine block. Look for corrosion, discoloration or fresh coolant.

2. Check the hoses that connect the radiator, engine and heater core for for bulging, cracking or splitting. Look for fresh coolant, discoloration or corrosion. Ispect the connections between these auto parts to ensure they haven't loosened.

3. Use a flashlight to inspect the radiator for leaks. Examine the radiator for fresh coolant, corrosion or discoloration. Inspect the bottom of the radiator for leaks.

4. Remove the radiator cap and fill it with fresh coolant to within an inch of overflowing. Wait for the radiator is cool before opening it. Twist the cap one full turn to release the internal pressure. Step back, wait a minute and then remove the cap.

5. Switch on the engine, set the heater to high and allow it to run for about 15 minutes. Shut off the engine and recheck the hoses, water pump, gasket seal and radiator for leaks. If you still can't locate the leak, consult a cooling system specialist for further diagnostics.
