Old cracked or split radiator hoses are not efficiently cooling your engine which can cause it to overheat leaving you stranded. So maintain your 300C cooling system by replacing your old brittle hoses now before it's too late.
I did not install the heater hoses yet, but upper and lower radiator are looks and fits pretty good, does not comes with license plate frame tho and short breather hose could be added to complete the underhood look. Also had use different type of clamp for the upper hose where it connects to radiator, as one it comes with is pretty hard to reach to tie up
