Frequently asked questions

What does the cylinder head bolt do on a 300TDi?

The cylinder head bolt clamps the cylinder head onto the block on the 300TDi 2.5 litre diesel, holding compression on the head gasket and sealing the combustion chambers, coolant and oil galleries. The 300TDi uses ten head bolts tightened in sequence.

How many cylinder head bolts does a 300TDi need?

The 300TDi engine uses ten cylinder head bolts. They're sold individually, so order a full set of ten when removing the head. Replacing all ten together is standard practice, since mixing old and new bolts risks uneven clamping of the head gasket.

Can 300TDi cylinder head bolts be reused?

300TDi cylinder head bolts are torque-to-yield stretch bolts that are typically replaced rather than reused whenever the head is removed. A previously stretched bolt may not hold the correct clamp load, risking head gasket failure. Fit a new set and tighten in the specified sequence and stages.
