About Southern Core Radiators
Southern Core Radiators is a specialist supplier of high-quality vintage and classic car radiator cores, serving customers throughout New Zealand. We work exclusively with established manufacturers in the United Kingdom to source radiator cores that meet the exacting standards required for classic and heritage vehicles.
Many vintage vehicles were originally fitted with copper and brass radiators built to precise dimensions and specifications that modern replacements often fail to match. By sourcing directly from the UK, we are able to supply radiator cores that closely replicate original designs, ensuring correct fitment, authentic appearance, and reliable cooling performance.
Our focus is on supplying radiator cores for restorers, collectors, workshops, and classic car enthusiasts who value originality and quality. Whether the vehicle is undergoing a full restoration or requires a correct replacement core, we provide a straightforward supply service backed by clear communication and dependable lead times.
We understand that sourcing the right components for vintage vehicles can be challenging. Our role is to simplify that process by offering access to trusted overseas manufacturers, while handling the ordering and supply locally here in New Zealand. Each radiator core is ordered to suit the vehicle’s requirements, helping ensure compatibility and long-term reliability.
Southern Core Radiators is built on a commitment to quality, accuracy, and dependable supply. When authenticity matters and a correct radiator core is essential, Southern Core Radiators provides a reliable link between New Zealand owners and specialist UK manufacturers.

Why Our Radiator Cores Are UK-Sourced
Southern Core Radiators sources all vintage and classic car radiator cores directly from specialist manufacturers in the United Kingdom. The UK has a long-established history of classic car engineering and restoration, particularly for vehicles built throughout the early to mid-20th century.
Many classic vehicles found in New Zealand were originally designed or manufactured in the UK or Europe, meaning replacement radiator cores produced there are far more likely to match original specifications. UK manufacturers continue to produce copper and brass radiator cores using traditional construction methods that modern mass-produced alternatives often lack.
By sourcing from the UK, we are able to supply radiator cores that offer correct dimensions, authentic appearance, and dependable cooling performance. This is especially important for restorations where originality and fitment are critical.
Working directly with UK suppliers also allows us to access a wider range of vintage radiator designs and custom-specification cores. This ensures New Zealand restorers and workshops can obtain high-quality components without the uncertainty of sourcing overseas themselves.
