What are the effects of corrosion cavitation and electrolysis on the cooling system of a vehicle?

Electrolysis is the result of electricity flowing through your cooling system and causing an electrochemical charge across the aluminum. This results in rapid corrosion and severe damage to the components in your cooling system including discoloration, pitting, flaking, and pinholes.

Thereof, what causes corrosion in cooling system?

Air in the Radiator Rust in the cooling system can also be caused by air getting into the radiator when the engine cools down. As the coolant cools down, it contracts which can cause an air pocket. This can cause rusting, while also creating wear on the water pump's seal and bearings.

Beside above, what causes cavitation in cooling system? An increase in air bubbles in a cooling system can increase the potential for cavitation erosion (pitting) of metal surfaces. Increased air can enter the cooling system through cooling system leaks and/or a faulty radiator cap. The potential for liner pitting increases in cold weather.

Hereof, what would be the effect of excessive corrosion in a cooling system?

In cooling systems, corrosion causes two basic problems. The second is decreased plant efficiency due to loss of heat transfer-the result of heat exchanger fouling caused by the accumulation of corrosion products. Corrosion occurs at the anode, where metal dissolves.

How do you check coolant for electrolysis?

To check for electrolysis, use a digital voltmeter set for 12 DC volts. Connect one lead of the meter to the negative post on the battery. When the engine is cold, remove the radiator cap. Insert the other lead into the coolant in the radiator.
