4a - 4age head (gasket) torque settings

[maxhag]

I just want to confirm what the HEAD TORQUE settings for a 4A-C.

I found this, and it's differant to what members on this forum have told me..... And it says it's the same for 4A-C and 4AGE....





Anyone got GENUINE TOYOTA specfications??

thanks

For AE111 4A-GE: 30N.m + 90 degrees, + 90 degrees.

It would be safe to use the same spec for all 4A. Otherwise around 45ft.lb. I don't have the 4A-C specs right now.

would u use those same settings on a ae101 4age 20v with 0.5mm HG??

[Jonny Rochester]

Yes I would. But when you buy a head gasket, it usually comes with a bit of paper with recomended torque settings. And make sure the bolts have cleaned threads, often done on the wire wheel. And lube the bolts also.

yeah and dont forget to lube the washers, both sides.

when i torque down TRD head gasket's (0.5,0.8) i use the Bible's recomendations
200-400-600-730 kg-cm,

everything i have seen in measured in ft-lbs. How do you convert that?

[Jonny Rochester]

1 pound = 0.45 kg
1 foot = 12" = 0.3048 meters


1 ft.lb Torque = 1 foot x 1 pound = 1 pound x 1 foot = 0.45 kg x 0.3048 meters = 0.138 kg.m

So:
conversion factor is 0.138 from ft.lb to kg.m
conversion factor is 13.8 from ft.lb to kg.cm
