This kit replaces the whole set of ageing rubber cooling hoses on the M50 powered E34 with silicone: the upper and lower radiator hoses, both heater hoses and the two throttle body preheating hoses, six hoses in total. Each one is moulded in high quality silicone with three to five reinforcement layers, so it holds cooling system pressure and resists the engine bay heat that hardens and cracks the factory rubber. On cars with a manual transmission the lower radiator hose is shortened by 100mm during installation.
