Need torque and sequence specification for cylinder head of 2000 land rover discovery

Helpful Andrew (above) has provided details of one sort of 2.5 Land Rover engine. You didn't state which model you had.

There is a 2.5 fitted to the Freelander that is a vee-6 and the figures above do not apply.
For this engine the data page says there is no requirement to fit new bolts. I would say it is optional but the originals should be checked and any stretched or pitted/corroded bolts should be replaced. Thoroughly clean all threads and oil or grease the bolts.

Starting in the centre of a cylinder head and working outwards in a spiral pattern tighten the bolts in four stages (Nm) 25+25+25 and then by a further 180 degrees.

22 N.M. or 16 ft./lbs., tighten in alternating sequence.

They should be 95ft pounds ! but some years vary! So spend the 25 bucks on the manual for your year, make and model ! good luck!

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/jeff_24365d731679262d

Hope this helps you.

Cylinder head bolt's torque.

start in middle and work outwards alternately ,bolt torque 80lbs and pull down if three passes ,speed key --rachet- torque wrench .although iam posting this i never use a torque wrench i go by the feel of the bolt stretching ,make sure heads have been checked and skimmed before refitting

not sure if you know this but you can go to

mitchell1diy and for ten bucks you can get everything about your car.

Do not reuse the old head bolts. These are torque-to-yeild type bolts and stretch when torqued down.

Starting in the center and working your way outward:

1st step - 15 ft-lbs

2nd step - 90 degrees

3rd step - 90 degrees

Remember the head bolts are not reusable. They are stretched, not torqued. I can't post illustrations here but the pattern can be found at LR’s service website, www.landrovertechinfo.com (you can register for free). The bolts are tightened to a light torque of 15 foot pounds, then turned through two angles of 90 degrees each.

Stage 1 20nm
Stage 2 +90 degrees
Stage 3 +90 degrees

Try ebay for a shop/overhaul manual. Don't know of a free manual. Rovercannibal.com has used factory owners manuals but they are around $30 but they are not a shop manual. Is there something you needed to know specifically?
