Penrite Red OEM uses organic additive technology with silicates (Si-OAT) based inhibitors that doesnt contain amine, borate, phosphate and nitrite to provide excellent corrosion resistance and to extended service life up to 8 years or 500 000 km, whichever comes first. It is compatible with all plastics, rubbers and seals and will protect all surfaces from corrosion including aluminium and copper. Penrite Red OEM Concentrate is designed to mix 50% by volume unless specified otherwise by the vehicle manufacturer. Ideally mixed with de-mineralised water but thanks to the phosphate free formula Penrite Red OEM can be mixed with regular tap water. The mixing of coolant types and brands is not preferred practice. For top ups, ensure you select the same type/brand of coolant that your vehicle is currently using or select a coolant that is designed to be mixed. If you are performing a complete service or refill, ensure the system is thoroughly cleaned of existing coolant by using a radiator flush. A radiator flush will help remove built up sludge, scale and corrosion while also neutralising any existing coolant left behind, preparing the cooling system for a fresh, clean refill. 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.

Engine overheating with this product, BUT....
26 February 2023

I did a Nulon coolant flush including hose up the heater hose to properly flush the system. I then installed this red coolant. I've since experienced the engine over heating quite a bit on hills but never seems to go into the "reds" on the dash but gets to 3/4. Unusual behaviour. Before I had this product in, I had just normal tap water in the engine as part of the cleaning process. The engine never over heated with he tap water in. So God knows what's happening but I'm going to flush this red stuff and go back to green I think.

Penrite Coolant Concentrate.
29 January 2023

Was having heating problems with the gauge going up and down all day. Turns out it only had a very weak colour in the radiator so I bought the Penrite concentrate, flushed what was left in the motor and filled (5Litres) it with this. Temp immediately returned to normal and has been there ever since. Works so efficient at cooling the system.
