THERMOSTAT HOUSING (2.0L DIESEL) - BLIND HOLE FOR PVS CONTROL VALVE
FORD 1984-85 ESCORT, TEMPO
LINCOLN-MERCURY 1984-85 LYNX, TOPAZ
The tapped hole for the PVS control valve at the thermostat housing is intended to be a blind hole. The PVS valve is designed to sense temperature without coolant touching the valve and will read incorrectly if immersed in the coolant. Therefore, under no circumstances should the hole be drilled through to the coolant passage.
