10.10.2005: Oil lines
Unbolt the turbo oil feed line from the filter housing (12 mm socket), remove the oil return hose and undo the bolt that holds the turbo stay to the engine.

Garrett T25 turbocharger replacement performed on a 1996 Saab 900. The procedure is more or less similar for all Saabs using the B204-B235 engine families. Use new copper crush washers for all banjo bolts. It is also a good idea to get a new oil feed line, or at least clean the old one from sludge and deposits.

This article describes replacing a stock turbocharger with another OEM unit. For upgrade information, refer to this document.

Tools and supplies:

  • 13 mm wrench and socket (downpipe and turbo nuts);
  • 12 mm wrench and socket (banjo bolts);
