do88's coolant hose kit replaces the full set of factory rubber cooling hoses on the twin-turbo N54 engine in the BMW 135i and 335i. The kit covers the upper and lower radiator hoses, coolant pipe and bleed hoses, water pump, thermostat housing, transmission cooler and heater hoses, each molded from premium silicone with three to five reinforcement layers depending on inner diameter. The silicone construction resists the heat and pressure cycles that split and swell the aging OE rubber.
