ENGINE IDLE SPEED
Check and adjust idle speed to specifications.
Standard value: 850 f 100 rpm
ENGINE OIL AND COOLANT LEVELS
Prior to road testing, check engine oil and coolant levels, and fill
as necessary.
SHIFT LINKAGE
Start in Park position, depress detent button and slowly move
the gear selector through all ranges. The detent "clicks" should
correspond with the range indicator.
DIAGNOSTIC ROAD TEST
Prior to road testing, perform the preliminary inspections
outlined earlier. If the car is not equipped with a tachometer,
install a portable tachometer in the car. And also install a
suitable vacuum gauge and pressure gauge. If the customer
has a specific complaint, select road conditions similar to those
described. (e.g. steep hills, freeways, etc.)
Follow the test sequence as outlined in this section and mark
the results on the Symptom Chart on page 21-64. It may be
necessary to repeat sections of the test under different throttle
conditions (e.g. light, medium or full throttle). After completing
the road test, compare the test results to the Troubleshooting
Chart on page 21-60.
ROAD TESTING
PARK RANGE
Place the selector lever in "P" range and start the engine.
Stop the engine and repeat the procedure in all other ranges
and neutral. In park, the car should be locked in position, unable
to roll or move. Mark all results on the Symptom Chart.
REVERSE
Manually shift the selector lever from "P" to "R", and note
shift quality. Drive the car in reverse long enough to detect
slippage or other abnormalities. Note results.
NEUTRAL
Manually shift the selector lever from "P" to "N" and note
quality. In neutral, there should be no movement. Note results.
