Coolant

Coolant – Engine Protection, Heat Transfer & Corrosion Control

Engine coolant (also called antifreeze) regulates temperature, prevents corrosion, and protects the entire cooling system from extreme heat or freezing. Over time, coolant breaks down and loses its protective additives, allowing scale and rust to form – leading to overheating or head gasket failure.

Our coolants meet OEM specifications for temperature stability, corrosion resistance and long service life. Whether you prefer Oscar Lubricant's advanced long-life formula, Plexus’ high-performance glycol blend, or Hepu’s trusted German technology, every option delivers reliable protection for South African driving conditions.

How to Check Coolant Level Safely

Never open a hot radiator cap — wait until the engine cools completely. Check that the coolant level is between the MIN and MAX marks on the reservoir. If the fluid looks rusty, oily, or low, top up with the correct coolant type and have the system pressure-tested to prevent hidden leaks.
