The length of time to replace a radiator in a semi truck varies with the make, model and accessibility of the radiator within the engine compartment. Also the professional experience of the mechanic and the facilities and equipment in the repair shop can affect the total amount of time taken. In many cases not only the truck radiator needs to be changed but hoses, clamps, sensors and other accessories may also need to be changed. As a rule of thumb a reasonable average time to replace an average radiator in a truck would be somewhere in the range of 3 to 6 hours depending on the job.
