Hi all, new to the forum, Im in the process of replacing my Vulcan headgasket and got my heads from the machine shop with new valve seats and cleaned everthing. Anybody have a service manual or infos about the head bolts torque sequence and specs.


Thanks

 

Welcome to the forum

2007 will use Torque to Yield(TTY) head bolts so you MUST use new head bolts each time

Sequence and torque specs seen here: https://ww2.justanswer.com/uploads/e...-07_162316.png

Tighten all bolts(60ft/lb) to set the gasket, then loosen all bolts 1 turn
Then follow the directions

To do the 90deg(1/4 turn) put wrench handle where you will have enough clearance to rotate it 90deg(1/4turn)

 

Hi, wow thanks for the fast reply, Im working on it after diner, yes I bough all new gaskets set and bolts from mahle, do you have more info for the other torque sequences and specs for the other upgoing steps (intake runner, valve cover exhaust manifold, lifters) thanks in advance !!!

 

For lower intake its the same sequence as head bolts, start in the middle and crisscross out to the ends, that's pretty much for any engine parts that have opposing bolt
On any bolts that have final torque under 40ft/lb its good to use Loctite Blue on the threads, this prevents them from loosening up during heat up and cool down cycles of the engine
Although NEVER use it on exhaust system, they have there own "rust-tite" at work, lol


Have a look here: https://www.therangerstation.com/tec..._through.shtml

1999 will be the same, but you may have a plastic upper intake, in which case you use 89 INCH/POUND NOT ft/lb torque, so 89in/lb = 7ft/lb
