A radiator module for commercial motor vehicles, in particular for agricultural tractors, has a support plate ( 7 ) fixed to the chassis and at least one coolant radiator ( 10 ) fixed to the support plate. The radiator has a radiator block ( 17 ) and two coolant tanks ( 19, 20 ) oriented at opposite ends of the block with one tank ( 20 ) adjacent the support plate ( 7 ) and one ( 19 ) spaced away form the support plate. In order to increase the cooling performance of the radiator module ( 6 ) despite keeping the installation space above the support plate ( 7 ) constant it is proposed that the coolant tank near the plate ( 20 ) is constructed from two mutually complementing tank parts ( 26, 28 ). The first tank part ( 26 ) is assigned to the radiator block ( 17 ) and has an encircling flange ( 25 ) for pressure sealed attachment of the coolant radiator ( 10 ) on the support plate ( 7 ). A second tank part ( 28 ) is assigned to the support plate ( 7 ). By dividing the coolant tank ( 20 ) into two parts, one on the radiator block ( 17 ) and one on the support plate ( 7 ) the effective heat sink area of the coolant radiator ( 10 ) can be substantially increased. On the one hand the enlargement is due to the fact that the flange ( 25 ) encircling the first tank part also serves to attach the coolant radiator on the support plate and in this region an assembly gap is therefore left between these components. On the other hand the enlargement is due to the fact that by moving part of the coolant tank under the surface of the support plate, the overall height of the coolant radiator is increased accordingly.
