Information:
This troubleshooting guide, when followed exactly as shown, can be an aid for the serviceman to find the cause of existing problems. The information from the measurements will also show proof if there is any basis for the complaint.Be sure to get a good description of the problem from the operator and/or the person who owns the vehicle. What they tell you about the problem can save you time and make the repair job faster and easier.Low Power And High Fuel Consumption Problems
The troubleshooting charts that follow provide a definite sequence to be followed for a logical, one by one elimination of many variables. The encircled numbers do not designate steps, but are references to detailed instructions that can not be shown on the chart. Always read the written material that corresponds with the encircled numbers on the charts.The Primary Engine Tests consist of quick and easy procedures that could identify the problem with a minimum loss of time. Always make these tests before starting the more involved troubleshooting charts.The necessary instruments to check each problem in sequence are shown on the chart. If the correct instrument is not available for the test, do not continue. The vehicle must be sent to a shop where the necessary tools are available.Whenever a problem is found and corrected, always run the test again to that point to be sure there is not a combination of problems. When the problem has been corrected and the complaint resolved, stop the test. Do not continue through the complete procedure just because it is there.When investigating possible causes, follow the letter sequence shown. Possible causes are arranged in order from more probable/easiest to check to less probable/more complex to check.Other Problems: Vehicle Or Vehicle Operation, Misfiring And Running Rough, Too Much Exhaust Smoke, Difficult Starting, Cooling System, Loss Of Coolant, Or Fuel In Crankcase Oil.
The probable causes of a problem are given in the order they most commonly take place. Check the probable causes in the same order that they are given. When troubleshooting, use the section on recommended procedures which follow each chart to check and make the necessary corrections for each probable cause.Engine Vibration Problem
The troubleshooting chart provides a definite sequence to be followed for a logical procedure to determine the frequency and amplitude of vibration so that the source of the vibration can be located and corrected.
