63 327/300 temperature switch

[Kerry A.]

I am in the process of installing a new thermostat and while doing so I removed the temperature switch to clean and inspect. I'm ready to reinstall and I checked my shop manual and AIM for torque specs but I'm unable to locate. Is there a torque spec and if so what is it and where can I locate it for future reference?

Kerry, The temp. switch is a pipe thread and I don't recall any torque spec.s for it. My advice is to use a wrench and tighten by hand. the 327/300 should have a case iron manifold so once it bottoms in the hole maybe give it another 1/4 to 1/2 turn.

I don't think there are torque specs for NPT - just tighten until there are no leaks. Put a thin film of pipe dope on it and maybe -10 lb-ft. If it doesn't leak, you're done.

Find "AC" or "AC Spark" wording somewhere on that sensor?

Kerry,

The correct torque spec for the temp sender is 15-20 ft lbs. I would go with no more than 15, and possibly a bit less.

The info is shown in the 1963 shop manual.
