MAN Cylinder head 51031006598

About this part

Genuine MAN cylinder head for the D2862 LE463, LE422 and D2868 LE433, the 24.24-litre V12 and the V8. Head bolts on engines of this class are generally tightened by an angle method into their yield range, which stretches them permanently — they cannot be relied upon to produce the same clamp load twice, and MAN specifies replacement, not reuse, where that applies. The temptation to reuse them is strongest exactly where it matters most: a head joint that loses clamp load leaks combustion gas into the coolant, which is a failure that escalates once it starts. Where the bolt specification is unclear from the documentation, new bolts are the inexpensive side of the decision by a wide margin. A head joint that loses clamp load leaks combustion gas into the coolant, and once that starts it only gets worse.

Supplied new, in the manufacturer’s packaging, with our warranty of up to 24 months.
