How to Check for Cooling System Leaks in a Ford Explorer

Iskandar Blogger 9:00 PM

The cooling system in your Ford Explorer is an integral part that enables it to operate efficiently. Checking for leaks on a periodic basis, or when there's a noticeable drop in coolant level, is imperative. To perform a cursory check, look on the ground underneath where you regularly park your SUV for coolant leaks. However, there are also more thorough methods to verify cooling system leaks.

Instructions

    1

    Open the hood of the Ford Explorer, grab a flashlight and inspect the radiator for any possible leaks. Look for any signs of fresh coolant, discoloration or corrosion on the radiator. When conducting the inspection make certain to check the bottom part and underside of the radiator, as it could've sustained damage from rocks or road debris during the normal course of operation.

    2

    Examine the cooling system hoses that connect the radiator, engine and heater core. These hoses are rubber composites, which make them susceptible to bulging, cracking or splitting. If you notice any of these signs of damage on the hoses, then look for corrosives or fresh coolant on the hoses, and also, inspect the places where the hoses connect to these auto parts because engine vibration can loosen the connections.

    3

    Check the water pump and gasket seal for cooling system leaks. The water pump is between the radiator and the engine block. The gasket seal securely attaches the water pump to the engine. Again, look for discoloration, corrosion or fresh coolant, as these are sure signs of leak.

    4

    Remove the radiator cap cautiously and add fresh coolant. Twist the radiator cap one full turn, step back, wait a few minutes and then completely remove the radiator cap. Be sure the radiator is cool to the touch before removing the cap. Never try to open a hot or warm radiator, as the internal pressure can cause an eruption that will burn anyone in the vicinity.

    5

    Turn the engine of the Ford Explorer on with the heater on high. Let it run for about 15 minutes or take it for a short drive.

    6

    Switch off the engine and inspect the water pump, gasket seal, radiator and hoses once again for cooling system leaks. If there still aren't any signs of leakage, the problem is most likely internal. Take the Ford Explorer to a cooling system specialist to locate the internal leak.
