Valve springs removed (05-2500)
Operation no. of operation texts and work units or standard texts and flat rates
| Valve springs | clean. Replace valve springs which are not to dimensional tolerance, are corroded, have surface rust, mechanical damage or worn at the ends. |
| Color coding on valve springs | check, match, see table. |
| Spring force | measure at pretensioned length. If the valve springs do not achieve the specified spring force, they cause a loss of frictional connection at high engine speeds and should be replaced. |
