The average cost of a Mercedes radiator cap is between $4.19 and $34.99.
The radiator cap on your Mercedes GL450, seals off the entire cooling system. That’s right, this tiny plastic or metal cap provides the pressurized seal necessary to maintain the proper flow of Mercedes coolant throughout your Benz. If your Mercedes-Benz radiator cap loses its ability to grasp the threading, your coolant will prematurely evaporate and compromise all of your coolant hoses and the radiator itself. When your coolant heats up to its boiling point upon startup, the coolant will make its way through your radiator hoses to the expansion tank for cooling. If coolant pressure is lost, you may notice your coolant hoses that run away from the radiator in a collapsed position.
Of all the DIYer repairs you can do to your Mercedes E320, replacing the radiator cap is like replacing a light bulb. It’s that easy. Ensure that your vehicle has sufficiently cooled if driven recently and just unscrew the old cap for the new. Many of the replacement Mercedes radiator caps on our site are less than $20 on average.
