Service Information
SUBJECT:
INSTALLING NEW TYPE HEATER VALVE AS A ISSUE: 01/87-915 SPARE PART
APPLICATION: 1984-85-1/2 900 MODELS, (1979-83 MODELS NOT AFFECTED)
A new black plastic heater valve with a stainless steel spool valve was introduced at the beginning of 1987 new car production. Recently, all earlier
designs of heater valves were superseded to the new design in the spare parts supply. This means that only the new design is available for 1979 and later
900's.
Special precautions must be taken when installing the black plastic heater valve in 1984-85-1/2 900 models built within VIN Serial Number ranges given
below. Due to the overall size differences between the new heater valve and the older style, the throttle pedal arm must be replaced with a later type
when installing the black plastic heater valve in 1984-85-1/2 900 models. Failure to do this may result in interference between the pedal arm and the
heater valve.
Although 1979-83 models are not affected and the new style valve may be installed without modification, the technician should make a visual inspection
to insure that prior modifications have not been made that might cause interference.
