I like to stay on top of maintaining my 2006 Acura TSX my question is does any of you change the upper and lower radiator hoses at any specific mileage or age? Or do you leave on until a leak occurs? I currently have 90K miles.

 

I inspect them for leaks or bulges and replace as indicated.

OEM hoses are good, but don't last forever. Not too hard to replace to avoid surprises.

good luck
