Install the tee in a location where you can directly read the reading (the figure shows an example).
Start the engine and measure the vacuum created by the vacuum pump.
- Standard: -87 - (-101) kPa (-650 - (-760) mmHg Art.)
If standard pressure is not maintained, check for air leakage in the system and remeasure.
If the standard pressure is not obtained on recheck, replace the vacuum pump.
Remove the vacuum pump following the drawing.
Attention: Do not disassemble the vacuum pump (do not loosen the M6 bolts (3 pcs.)).
