Need torgue specs for bolts on head of my 2000 vauxhall tigra 1.4


Cylinder head bolts (You must use new bolts)
stage 1 ... 25 Nm (18 lb ft)
stage 2 ... angle tighten + 90 degrees
stage 3 ... angle tighten + 90 degrees
stage 4 ... angle tighten + 90 degrees
stage 5 ... angle tighten + 45 degrees

Remember use NEW bolts, these are called torque to yield bolts, they stretch like a linear spring and they only last one use.

Can anyone help? i need torque settings for head gasket and settings for inlet tappets and exusht


Find complete torque specs here:
http://fme-cat.com/LiveDocs/99999.pdf
and don't forget that you MUST buy new head bolts since they are torque to yield and MUST OT be reused!!

I suspect that you at least need to check the valve lash but as long as your head gasket is not dramatically different than original (which it should not be because that would change your compression ratio) you should be close to okay (I would check it). Or if you had any machine work done to the head, in which case you certainly would need to adjust the valve lash.

Torque specs for 3.9l engine cylinder head and crankshaft bolts.


Page 3-26 of Chilton's reads:
14. Using no sealer whatsoever, install the new head gasket(s) to the block. Clean, dry and lightly oil all head bolts threads. Install the heads and install the head bolts.

Tighten head bolts in sequence to 50 ft. lbs. (68Nm). Repeat the sequence retightening the bolts to a final torque of 105 ft. lbs. (143 Nm) and repeat the second step to ensure that all bolts are accurately torqued.

torgue chart from chilton (page 3-11) for your engine and year show:
main bearing bolts 85 ft lbs
rod bearing bolts 45 ft lbs
crankshaft damper bolts 135 ft lbs
flywheel bolts 55 lbs

Head bolts


I'm assuming you meant a 1.8L 4V, if so the torgue settings for the head bolts are
stage 1: 30 ft-lbs
stage 2: 44 ft-lbs
stage 3: Angle-tighten a further 90-degrees
stage 4: Angle-tighten a further 90-degrees

Also I recommend you buy new cylinder head bolts from the vdub dealer, they say you don't have to with a gas engine but only with diesel engines you should, from my past experience it felt like the old bolts were going to snap off to be safe buy new ones. If you have never done this before "stage1" this means each bolt gets this one time, then after you have done each bolt at this torgue then you do the bolts again (stage 2) with this torgue ect. Remmeber to always cris cross your bolting and work from one side to the other the same time for each stage. Vdubs 4-ever !
