SOURCE: Head Bolt Torque for a 2000 Grand Cherokee Laredo 4.0L

the torque is a 4 step process

1 torque all bolts to 22 ft/lbs
2 torque all bolts to 45 ft/lbs
3 recheck all bolts to 45 ft/lbs
4 torque bolts 1 thru 10 to 110 ft/lbs
bolt 11 to 100 ft/lbs
bolts 12 thru 14 to 110 ft/lbs
bolt #1 is the fourth bolt from the front on the passenger side....#2 is the fourth bolt on the drivers side then you continue in a clockwise order

SOURCE: Head bolt torque specs needed for 96 tbird 3.8

Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:

  1. 20 Nm (15 lb-ft).
  1. 40 Nm (30 lb-ft).
  1. 50 Nm (37 lb-ft)
Loosen retaining bolts one at a time two to three revolutions and retighten as follows:

Long bolts:
  • Tighten to 40-50 Nm (30-37 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Short Bolts:
  • Tighten to 20-30 Nm (15-22 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Here is a pic of the sequence

5.7l engine. How should I remove cylinder head?


If intake and all head bolts are removed, chances are the head is stuck to the gasket/block. The head will normally sit upon 2 dowel pins which will also,hold it secure. Use a prybar and gently apply force to the head. It will come loose

Have a problem with my isuzu bakkie kb 260 oil and water mix after driving for 20 km


Run a coolant pressure test to look for pressure leaks. I suspect that it will be behind the water pump impeller that corrodes from water turbulence and allows water to leak through pin holes into the sump. It could also be a head gasket of head bolts leaking past the head studs/threads so a compression test may also help. By removing the rocker cover and with the coolant system under pressure you may see droplets of water at a head stud.

My have a blown head gasket on my 2000 Honda Accord V6. What could have led to this problem?


most common causes of blown head gaskets are engine overheating. could be caused radiator cooling fans inoperative, cooling system leaks, clogged radiator passages,or sticking thermostat. if a head gasket is severely blown the cooling system will pressurize very rapidly on cold engine startup. other more rare cases of head gaskets blowing could be loose head bolts. make sure new head bolts are used and torqued correctly if service manuals recommend new head bolts.

Change head gasket on 65 mustang 200


Drain antifreeze -DON"T POUR IT DOWN A STORM DRAIN - then remove valve cover, Remove exhaust from head assembly. On this engine the head is also the intake manifold - it's cast as a unit. Remove carb and remove heater hoses from carb base plate. Remove head bolts and discard. Break head loose from block - may have to smack it a time or two to break gasket loose. Get a buddy to help lift the head off the block - it's fairly heavy. Clean gasket surfaces on both head and block. Install new gasket onto block - pay attention to gasket orientation - it goes on only one way correctly. Reverse procedure to re-install - USE NEW HEAD BOLTS! Silly to try to save $20 bucks on bolts and ruin an engine.

1987 toyota pickup with 22r keeps blowing head gasket


Your head bolts are stretched, when it got hot it weakened the metal in the bolts which means that the bolts cannot hold the needed tension on the head. Replace the bolts and you will stop blowing head gaskets. Also use Genuine Toyota head gasket, It will be a bit dearer but they are much better than aftermarket options.
