Description
This is an updated accordion style bypass cooling hose with the two metal hose clamps that goes in between the cylinder head and water pump on BMC A-series engines. The advantage of the accordion style hose is that you do not need to remove the cylinder head when you need to change the water pump. This hose is able to compress upwards to remove the water pump, unlike the original straight hose that is not flexible and the cylinder head must be removed. Be sure to change this hose every time you change the water pump or remove the cylinder head. Also the inside of the hose can deteriorate which is called and electrochemical attack on the rubber compound in the hose from sitting for long periods. This is most common failure hose failure now days in Classic British cars. Cross Ref.# 312, 434-530, 2A242, 3H2963, CH0085, CH85, GZA2083NF, GZA2083, GZA2083Z
