Frequently asked questions

What does the Cylinder Head Bolt do?
The Cylinder Head Bolt clamps the cylinder head to the block on the AJ-series V8 petrol engine. It's an M10 x 175mm torque-to-yield fastener that stretches slightly when tightened, holding the head and gasket at the correct clamping load. This is the genuine Land Rover bolt.
Do these head bolts need replacing every time?
Yes, cylinder head bolts are single-use and must be renewed whenever the head comes off. As torque-to-yield fasteners they stretch on tightening, so reusing one risks losing clamping load and a head gasket failure. Fit a complete set of new bolts on reassembly.
How many Cylinder Head Bolts are fitted per engine?
A full set is typically around twenty bolts per V8 engine. Since they can't be reused, order enough to replace every head bolt. Tighten them in the correct sequence to the workshop manual specification when refitting the cylinder head.
Which engines use this M10 x 175mm head bolt?
This head bolt fits the Discovery 3 and 4, Range Rover L322 and Range Rover Sport L320 with the AJ V8 petrol engines, including the 5.0L AJ133 from VIN AA000001. Confirm your engine variant and VIN before ordering to be sure of the match.
