How to Check for Cooling System Leaks in a Geo Tracker

Iskandar Blogger 2:20 AM

To keep your Geo Tracker operating at peak efficiency, it's necessary to perform periodic maintenance checks. Checking for cooling system leaks, for example, can help prevent permanent damage to the engine. One way to check for leaks is to examine the area beneath where you normally park your Tracker for fresh coolant leaks. This simple method is but one of several, you can use to check for cooling system leaks.

Instructions

    1

    Open the hood of the Geo Tracker, grab a flashlight and use it to inspect the radiator for leaks. Look for signs of fresh coolant, corrosion and discoloration anywhere on the radiator. Be certain to check the underside and bottom part of the radiator for leaks, as it could've sustained damage from rocks and road debris.

    2

    Inspect the hoses that connect the heater core to the engine and the engine to the radiator for signs of leakage. The heater core is behind the engine and close to the windshield. Check these hoses for bulging, cracking and splitting. Even if any damaged hoses show no signs of leaks, it's still a good idea to replace them, as they eventually will start to leak.

    3

    Check the water pump and gasket seal for cooling system leaks. The water pump on a Geo Tracker is behind the engine fan and the gasket seal securely attaches the water pump to the engine block. Examine these parts for fresh coolant, discoloration or corrosion. If there are signs of leakage, you'll most likely need to replace rather than repair the water pump or gasket seal.

    Remove the radiator cap and add fresh coolant to within an inch of overflowing. Be certain to check the external temperature of the radiator before you take off the cap. Never open a warm or hot radiator, as the internal pressure can cause an eruption, which will spew hot coolant and burn anyone in the vicinity.

    Start the engine of the Geo Tracker, set the heater to high and let it run for about 15 minutes; take it for a drive, if you prefer. Shut the engine off and check the water pump, gasket seal, radiator and hoses for leaks one more time. If you still can't find the source of the leak, then it's most likely an internal cooling system problem and you need to consult a cooling system specialist to indentify and fix the problem.
