How do you prevent electrolysis in a radiator?

ALWAYS make sure the radiator is not used as a ground and that all components are functioning properly. Periodically test your system and check for any discoloration or pinholes – especially around the tube-to-header joints and tubes near the center of the core by the electric fan mounts.

Correspondingly, how can electrolysis be prevented?

There are five ways to protect your boat against corrosion including:

  1. Isolate corroding metal from seawater by painting or coating.
  2. Change potential of metal by introducing sacrificial anode.
  3. Making metal passive by using corrosion inhibitors.
  4. Change the pH of local environment by chemical dosing.

Additionally, how do you test for electrolysis in a radiator? 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.

Likewise, people ask, what causes electrolysis in cooling system?

Electrolysis damage in an engine cooling system is caused by unintended electrical currents that flow from voltage differences that exist in the engine coolant jacket, the radiator, and the heater core. The damage can include rapid corrosion, pitting, flaking, and pinholes. The engine coolant is the electrolyte.

How can you detect a stray current in a cooling system?

To test for stray/electric current, use an analogue voltmeter with sensitivity of 0.03 volts or a stray current detector by first placing the positive lead directly into the coolant (through the filler neck on the radiator), or in the overflow bottle (for a closed system), making sure that the terminal is not in
