first off , the service manual did not lie to you. get it and read it first? the real book or reading internet lies from google searching, 3.5L V6 would you blow up and engine off of internet lies, well NO. no year car told. nor in what country. not told which of the 3 , 3.5L engine is is. only used here USA in 1997 to 2002 in say Montero
it needs to be timed correctly , or risk bending all head valves. most DOHC cam engines are interference. the High CR one is .
ok here is your answer the tension'er on this engine is a separate part
if you read the cars service manual all this is covered fully buy it and not wreck valves is a win ( all 3 shown here) It is not one engine is 3.
6g74 IS MADE IN 3 TYPEs of CR, heads CR= Compression ratio. this: 9.5 (SOHC); 10 (DOHC); 10.4 (DOHC GDI) 3 ENGINES MADE, WHICH ONE YOU HAVE NOT TOLD 3 different power spec. HP or KW
SOLD WITH 3 ENGINES, AND LAST ONE IS DOHC AND INTERFERENCE AS 99% ARE,
best is set #1 firing TDC and replace belt and not move cam or crank, win./!! do so on all engines and win, no bent valves ever.
1: set TDC 1 firing. 0 degress 2; off the tensioner (linear rod type) 3: off the belt 4: preload he tension'er use a nail. 5: remount the tension'er device. new belt on pull the nail above. and so on, reverse of dismantle.
there's no one torque setting. there's multiple stages and a sequence you have to do it in. usually finger tight, then tighten to a torque setting spiraling out. then torque it further so many degrees.
check the pajero 4m44 forum for exact specs. got manual at hm. have look later.
what car? and year>? and country , so we can look it up in our
great online sources. (all 3 must be known)
in the USA we use alldata.com (or the dealer FSM)
i guess you dont know that some heads are not torqued, or use TTY bolts, right? some are set by ANGLE degree.
that is covered in the FSM all that. the facts.
most head failures result from guessing.
or asking here, with no facts on car.
some engine run different heads, and different if turbo.
