Heater hoses for cars up to 1991 used heater matrix BAU5043 and were on the right hand side of the heater, whereas later cars used JEF10005 heater matrix and were on the left hand side of the heater, hence different hoses from item 17-21
Cars from late 1984 to late 1988 had 5⁄8”outlets on the heater matrix and will require 5⁄8”hose and then reducers
MOC210 from 5⁄8” to 1⁄2”size, to enable using 1⁄2”hose to fit the heater valve and bottom hose.
The 1⁄2”silicon hoses when well lubricated will push over the 5⁄8”matrix outlets as they are of a more supple and longer lasting material.
