Access to relays situated behind the front
cover of the relay box is by removing the four
hexagon-headed screws, then drawing forward the
cover.
Note The coolant probe and head flick relays
are secured to the cover, therefore it is
essential that no attempt be made to
remove the cover completely until the
' Lucar' connectors have been dis-
connected from the relay terminals.
