The Coolant Tester is a simple to use device that helps you to check your radiator coolant
This Coolant Tester quickly checks the specific gravity of your engine coolant water and shows you whether you have enough anti-freeze (Ethylene Glycol) or Corrosion Inhibitor in your cooling system.
The correct Antifreeze level is critical to protect A/c Evaporators/Heater cores from freezing and splitting the cores.
Your engines cooling system is a vital part of your engine. Without water, your engine will quickly overheat and seize. This is a common cause of blown head gaskets.
Today’s aluminium cylinder heads and engine blocks have the added problem of the water in your cooling system can corrode the aluminium and cause severe damage to your engine. Coolant additives prevent corrosion as well as preventing your coolant from freezing and cracking the block.
