Same as a coupe or touring, hand tight with a short handled ratchet wrench. For head bolts torque matters, for most other bolts no.

Only a 3/8” thread, use a 7” long sm. handle ratchet , you’re only compressing the soft gland gaskets, if you have to use a fancy torque wrench, max of 15 lb/ft or so.

I use what I got. I happen to have one of those fancy torque wrenches from my young days.

Thanks for the help, Jed

You tighten a nut until just before it strips.

Or, tighten it up until it strips, then back off half of a turn. :roll: I know, it doesn't make sense, but that's one of the expressions that I grew up with from back in the early '50's, sort of like "jack up the radiator cap and roll another car under it", to describe a badly worn out (junk vehicle) vehicle. :lol: Dave

The one I remember was " Tighten till failure then 1/4 turn" seems about right. :) . Jim
