Can anyone confirm the tq spec for the flywheel on a 2.4L? Manual trans, isuzu.
I can't remember exactly, but I believe it's 180 in. lbs Is that correct?
unsure on the correct torque spec but i do remember you need to turn another XXX turn AFTER you get them torqued...
its either 1/4 or 3/4 turn i cant remember for sure.
This is the voice of experience talking here. The tq spec is use high strength thread lock and get them tight. I am not talking about using a breaker bar tight but nice and snug with a 3/8 drive rachet and socket. You don't want those bolts coming loose!
