Checking and Adjustment Values (X 25 Xe, Y 26 Se)
| Engine | X 25 XE | ||
|---|---|---|---|
| Idle speed | |||
| with manual transmission with automatic transmission | rpm rpm | 570 - 730 570 - 730 | |
| Maximum rpm | rpm | 6800 | |
| CO content | Vol. % | ||
| Spark plug electrode gap | mm | 0.9 - 1.1 | |
| Compression pressure | kPa | 1200 - 1500 | |
| Pressure loss | not more than 25% per cylinder | ||
| Valve clearance | mm | 0 | |
| Ignition timing at idle speed |
When checking the idle speed and the CO content, ensure the following:
- Electrical consumers switched off
- Engine at operating temperature (oil temperature ≥ 80 �C / 176 �F).
- Selector lever in position "P" with automatic transmission
- CO test with 2,800 to 3,200 rpm without load
