Peugeot 306 head bolt torque setting?

The Peugeot 306 head bolt torque setting is 20 Nm (15 ft-lb). This is the torque specification for all 306 models, regardless of engine type.

When torquing the head bolts, it is important to follow the proper sequence. The sequence is as follows:

1. Bolts 1 and 6

2. Bolts 3 and 8

3. Bolts 2 and 7

4. Bolts 4 and 5

Tighten each bolt to 20 Nm (15 ft-lb) in the specified sequence. Do not over-tighten the bolts, as this can damage the head gasket.

Once all of the bolts have been torqued, re-check the torque setting after the engine has cooled down. This will ensure that the head bolts are still properly torqued.
