Keep your vehicles cooling system in perfect order with Penrite 10 Tenths Race Coolant Inhibitor Concentrate. The race proven corrosion inhibitor features hybrid organic acid technology (HOAT), lowering coolant temperatures and offers long term protection for up to 3-5 years or 150 000km, whichever comes first. Penrite 10 Tenths RCI is designed to provide better heat dissipation by preventing cavitation, decreasing operating temperatures and protecting your engine. It is compatible with all rubber hoses, seals and gaskets and will provide protection to all metals such as aluminium, brass and copper.

To find the correct coolant suggested for your vehicle; either add your vehicle to My Garage or check with your manufacturer, vehicle user manual, your local mechanic or head in-store and talk to one of our friendly team.

I recently purchased this product to use in my racing go karts and Formula 125s. I found it to be an excellent product to help protect my racing engines and to keep them cool to the maximum ability and to maintain peak performance when used in racing. I would highly recommend this product to anyone who wants the best for their own engine.
