Found in most modern vehicles, plastic tank/aluminium core radiators offer the benefits of being lightweight and excellent thermal efficiency, making them the preferred choice for original equipment. Plastic tanks are fitted to ‘tabbed’ headers using an o-ring to create the seal.
Over time, plastic tanks can deteriorate and become brittle; the aluminium cores can be easily damaged if not treated carefully and are very difficult to repair if they develop a leak. Full radiator replacement is often the only remedy in this instance.
Classic cars and older vehicles and equipment have copper/brass radiators. These are heavier and more expensive to manufacture than their modern counterpart but have better corrosion resistance and durability. If the radiator develops a leak, soldering can seal it rather than having to replace the unit. If blocked, the tanks can be removed to allow the core to be cleaned out and the tanks soldered back on again. The core can also be replaced and upgraded with extra rows if required.
Performance Alloy Radiators
Welded construction combined with a high efficiency core makes full alloy radiators ideal for high performance cooling applications and are often used for cooling modified engines. The polished finish means they also look great. A wide range is available but if special design or fitment requirements are needed, then a custom built radiator may be the solution.
