Copper Radiators

If you own an older vehicle, the original radiator may be a copper / brass radiator. While a copper radiator is usually heavier than a modern plastic aluminium radiator, it has the advantage of being easy and inexpensive to repair.

Copper-brass radiators are used in passenger vehicles, 4WD’s and light trucks. The metals are less brittle and less prone to damage by electrolysis than alloy, surviving in environments with vibration and high thermal cycling.

Ask your Natrad specialist about the copper / brass radiator replacement and upgrade options for your specific application.

Yes, provided you follow the installation instructions including performing a stray current check, flushing the cooling system and correctly disposing of waste coolant. Failure to follow installation instructions will void the warranty.

Unlike a plastic aluminium radiator, tanks on a copper-brass radiator can be repeatedly removed allowing the radiator core to be cleared of any blockages. Small leaks can be patched by soldering the brass tubes, quickly returning the radiator to service.

Always ensure that the correct coolant for the vehicle is used, and that coolant is changed at intervals as recommended by the manufacturer. Getting your cooling system checked annually by a qualified technician will ensure that you are aware of any issues before they develop into major problems.

When correctly fitted, your copper radiator from Natrad has a three year warranty.

Keen 4WD owners may choose a copper radiator over a plastic-aluminium radiator because it’s properties make it easier to repair and maintain in the outback:

• Easy to repair using solder
• More tolerant to poor water quality than an aluminium radiator

Plus you can upgrade to a more efficient copper / brass radiator. For example, you could replace an original Landcruiser 70 series radiator with an aftermarket SLC unit from Natrad that contains 90 more tubes than the original design, offering much better cooling in the same size dimensions.

Yes, Natrad can supply Super Louvre Copper radiators designed for effective, compact cooling performance. These radiators typically contain a lot more tubes than the original (OE) copper / brass radiator for enhanced cooling.
