How to Check for Cooling System Leaks in a Saturn Ion

Iskandar Blogger 8:14 AM

To keep your Saturn Ion in the best possible working condition you should perform periodic system checks. Inspecting the cooling system for leaks is one of these checks. If the cooling system doesn't work correctly due to a leak, it can cause the engine to overheat and permanently damage the car. Checking the cooling system requires no specialized mechanical skill; just follow a few simple steps.

Instructions

    1

    Move the Saturn Ion from its normal parking place and look on the ground where it was parked. If there's a leak, there'll be bright colored coolant on the ground. However, even if there isn't any sign of coolant, it doesn't mean there isn't a leak. The heat from the engine can burn the coolant before it ever hits the ground.

    2

    Open the hood and inspect the cooling system hoses. Look for any bulging, cracking or splitting on the hoses. Also, check for any fresh coolant leaks, hose discoloration or corrosion. Be sure to check where the upper and lower hoses connect to radiator and the engine block, which can come loose due vibration from the engine.

    3

    Inspect the water pump and the gasket seal for any discoloration or corrosion. The water pump is behind the engine fan and attached to the engine block. The gasket seal is what secures the water pump to engine block.

    Check the radiator with a flashlight for any leaks. Be sure to look underneath the radiator as rock and road debris can damage the underside of the radiator during normal operation of the Saturn Ion. Again, examine the radiator for signs of corrosion, discoloration and fresh coolant leaks.

    5

    Confirm the external temperature of the radiator. If the radiator is cool to the touch, then proceed. If not, wait for it cool off before you continue.

    6

    Twist the radiator cap one full revolution and step back. Wait a minute or two and then completely remove the cap. Because of internal pressure, the radiator can erupt and burn anyone in the area, so take care when removing the cap.

    7

    Add fresh coolant to the radiator and start the Saturn Ion. Let the engine run with the heater on high for about 15 minutes. Next, shut off the engine to inspect all of the auto parts from the previous steps. If you still can't find the leak, the problem may be internal and you should consult a cooling system specialist for further diagnosis.
