To my amazement, i cannot find a tightening spec in the factory service manual for the engine’s coolant block drain plug. Looked under both Engine and Cooling System sections. A search here on Sl 6.org brought up nothing. This is for a 1981 hydraulic lifter 225 Slant 6. Here’s the plug: Attachment: block coolant drain plug Sl6org.jpg [ 22.89 KiB | Viewed 632 times ] Apparently last time it was out i just winged it when i put it back. Anyone know the proper torque? |

I thought that those were pipe thread. If it is, I don't think there is a torque value for it. |

I've had lots of those out, never torqued one w/a torque wrench yet. And yeah they're pipe thread I put petcocks in that hole like what's on the bottom of the radiator |
