Our high quality silicone coolant hoses are a must for the performance enthusiast. Silicone is a durable material that will not deteriorate and is unaffected by oil or fuel spills. The integral reinforcing material ensures that they do not deform in service. This kit is for MGBs from 1962 to 1976 but based on the later type (1971-76) cooling hose system . For early pre 1970 cars simply fit this one piece bottom hose without using the cast elbow and separate bottom hoses.
