EXHAUST
Exhaust: Precautions for the repair
19B
Exhaust trunking with 1 bolt
Exhaust trunking with 2 bolts
Fit the exhaust trunking onto the part of the exhaust
system fitted to the vehicle.
Position the pipe onto the lugs (2) inside the exhaust
trunking.
Tighten the exhaust trunking bolt(s) slightly (depending
on the version).
Position the second part of the exhaust system under
the vehicle, fitting it in the exhaust trunking.Position the second exhaust pipe onto the lugs inside
the exhaust trunking.
Check that the two cut marks (3) are aligned (if applica-
ble).
Position the trunking so that there is no risk of contact
between its bolt or bolts and the heat shields.
Torque tighten
-the exhaust trunking nut with 1 bolt (25 N.m) (if fit-
ted),
-the exhaust trunking nuts with 2 bolts (18 N.m) (if
fitted).
Check the following and deal with if necessary:
-no underbody contact between the exhaust system
and the heat shields,
-all of the heat shields are present and secure.
Start the engine.
Check that there are no leaks: deal with any leaks.
