How to Fix a Radiator Leak

Radiator is a component of the car’s cooling system. It is located behind the bumper for optimum heat removal when the car is cruising. There is a fan behind the radiator which is connected to a thermostat. When temperature exceeds allowable level, the thermostat will activate the fan, thus improving the heat removal capacity. Water pump will circulate coolant in and around the engine internals which absorbs excess heat and then dispersing it through the fins.

Then, inspect the external radiator body visually. Look for any indication of cracks, corrosion or any form of discoloration which may be significant visually. Else, use a radiator repair kit to fill in air into the radiator and then submerge the radiator completely into the water. Observe for any air bubble which may emerge from cracks.

Once the exact crack location has been identified, buy a stop leak additive to cure minute crack. Fill the additive into radiator and top up with distilled water only. Normal tap water contains minerals and contaminant which causes internal corrosion leading to radiator failure.

If the crack is severe, welding work is required to patch the crack. Determine the exact material before contemplating on the welding specifications and electrodes types to ensure perfect weld.

By following the given tips, I am sure you will appreciate your car better and save up labor cost.
