Replacement truck radiators at Truckstop Group
Truck radiators operate under sustained thermal stress: long motorway runs at high engine load, stop-start urban routes with frequent heat cycles, and cold-start conditions in winter all contribute to progressive degradation. Leaks around the end tanks, internal blockage from coolant contamination and external damage to the fins from stone strike are the most common failure modes. When a radiator can no longer maintain coolant temperature within the acceptable range, the engine management system will begin compensating, affecting fuel economy and power before any warning light activates.
NRF is the primary radiator brand in our range, with specific units stocked for Volvo and Renault applications — NRF 50190 suits Renault C and T series, NRF 50191 suits Volvo FH and FM variants. Nissens and DT radiators are also stocked for other HGV makes. Radiator hoses for upper and lower positions are available alongside the radiator units: where the hoses have been running on a failing radiator, replacing them at the same time avoids a second job in the near term.
Radiators are heavy components and are typically delivered on a pallet. Charges may apply — confirm delivery options and surcharges with us before ordering. Call our team with your chassis number for fitment confirmation and current stock availability.
Frequently asked questions
How do I know when a truck radiator needs replacing rather than repairing?
Minor leaks at fittings or hose connections can often be addressed by replacing the hose or clamp. Leaks from the radiator's end tanks, internal core blockage, or structural damage to the core itself typically require replacement. On high-mileage vehicles, replacement is usually more cost-effective than repair when the core is showing multiple degradation signs.
Should I replace the radiator hoses when fitting a new radiator?
If the vehicle has been running with a failing radiator, the hoses are likely to have been under additional thermal stress and should be inspected at the same time. Replacing hoses preventatively when fitting a new radiator avoids a second coolant system repair shortly after.
Are there delivery surcharges for truck radiators?
Radiators are large, heavy components and are typically shipped on a pallet. Pallet delivery charges may apply depending on your location. Confirm delivery costs with us before ordering, or collect from one of our Midlands branches.
