on the exhaust gas recirculation assembly,
- the bolts to the exhaust gas recirculation rigid pipe
on the exhaust manifold,
- the bolts to the exhaust gas recirculation rigid pipe
bracket on the cylinder head.
a Tighten to torque:
- the bolts of the exhaust gas recirculation rigid
pipe bracket on the cylinder head (25 N.m),
- the bolts of the exhaust gas recirculation rigid
pipe on the exhaust manifold (36 N.m),
