So not to warp the head and create leaks.
you need a chiltons motor guide don't count on what someone on the computer tells you ..this has to be right or you just wasted a lot of money

i need the torque sequence for a 1998 pontiac grand am 2.4 quad
The head bolts on a Briggs & Stratton 3.5 HP small engine typically require a torque specification of around 200-240 inch-pounds. It's important to follow the specific manual for your engine model, as torque values can vary slightly. Always ensure to torque the bolts in the correct sequence to prevent warping the cylinder head. Use a torque wrench for accurate measurement.
If your getting that far into the engine you need to at least by yourself a haynes or chiltons repair manual for the vehicle your working on because in some cases you need to replace the head bolts.
Torque sequence is: 7 3 1 5 9 8 4 2 6 10 Make sure all bolt threads and threads in the block are clean and lubricated lightly with oil. Pontiac do not need thread sealent since the bolts do not break into the water jackets. Start in the middle of the head and move outward.Torque in three steps first all bolts to 30lbft, then all to 60lbft, finally all bolts to 95lbft. after inital run in recheck the final (95lbft) torque after the engine has cooled.
The amount of pressure you need to tighten nuts or bolts.
The vehicle manufacturer will quote a torque figure for the EGR valve but in practice most mechanics no not torque them.
Torque for which bolts?? need more information.
wich bolts do you need the specs on
The cylinder head torque on a 2000 Honda Civic is set at two different rates. For placing the head correctly the bolts need to be tighten to 22 ft torque. Once correctly set the bolts will need 49 ft torque to be properly tighten.
the longer (new bolts) are to torqued to 48lbs and the shorter ones are to be torqued to 45lbs then turn the bolts an additional 90 degrees the bolts need to be replaced with new one because they are streched when you torque them down
