Man­i­fold change

Car Mechanics (UK) - - Help! -

I am about to re­place the ex­haust man­i­fold gas­ket on my 2000 Saab 9-5 2.3T as a cou­ple of studs are bro­ken and need to be re­newed. I’ve got a new gas­ket, but which way does the gas­ket fit? One side has a shiny me­tal face and the other is typ­i­cal dark gas­ket ma­te­rial, so which side faces the block? Also, should I fit the gas­ket dry or cover it with a light smear of Alu­minium LS159 grease, which I be­lieve aids fu­ture re­moval? Derek Houghton The shiny me­tal or sil­ver side faces to­wards the cylin­der­head. Saab lit­er­a­ture states that the gas­ket and studs should be smeared with a light coat of Moly­cote 1000 (part num­ber 30 20 971) or sim­i­lar; the Alu­minium LS159 will serve the same pur­pose. When re­fit­ting the man­i­fold to the cylin­der­head, the fix­ings should be torqued to 25Nm.
