A new radiator hose costs between $20.00 to $40.00 each depending on the make and model of vehicle.
So if you can remove the hose and replace it yourself then you can replace the radiator hose for the cost of the hose and your time.
All you have to do is drain the coolant and then remove the clamps to the radiator hose and slide the old one off and sometimes you may have to slice the old hose open to get it to come off the radiator and the engine port.
Sometimes the radiator hoses just come off but sometimes you have to cut them to remove them.
Then just replace the radiator hose and tighten the clamps and refill the radiator with coolant and you should be good to go.
If a shop replaces the radiator hose then it could cost you $120.00 to $200.00 for parts and labor depending on how hard it is to replace the radiator hoses.
When replacing one radiator hose you should replace both radiator hoses because when one radiator hose fails the other radiator hose will likely fail eventually and leave you stranded.
