w124 expansion tank hose question
 

Would the vehicle run too hot or otherwise suffer from a delay in replacing the corroded hose that runs from the expansion tank to the receptacle in the fender wall? Can the new hose just be stuck into the hole or does the fender have to come off? Thanks

Expansion tank to the overflow tank hose parts number is 007 997 26 82 to do this job the wheel liner have remove. that is only overflow hose will not cause engine overheating.
