Well, we were changing a couple rad hoses and decided to flush the whole system as well. The drain plug (block) was almost pooched/stripped so I'm wondering where I should get a new one. Dealership? Does anyone have any ideas? I could re-use this one but would be afraid that it's never coming off again...well at least without doing some damage. Thanks.

 

You could, but I'd just try and fine another one from someone parting out or at a bone yard. Much cheaper....maybe even free.

If the threads aren't completely destroyed, you could try repairing the threads with a bolt chaser or die. Make sure the block threads aren't pooched, also. You'll back in the same boat trying to put a plug back in.

 

Unfortunately there aren't any Toys in the yards around here....phoned the dealership though and they are getting one in from Cali. for $5. Not bad and shipping is paid.

 

Oh! Problem solved, then. Cool.

 

I'm just hoping the new one goes in smooth. Like you said though Thook, I can always chase it. Hope it works for $5!

 

I'm not sure if loc-tite or anti-seize would be appropriate in this situation. Whichever is, either one will lubricate the threads and make reinstalling easier. Less chance of it sticking and crossthreading.

 

I would use sum teflon sealant just to help seal it (it is part of the pressurized cooling system)

 

it is a good time to install a after market temp gauge that is where mine is installed.

 

What's your temp gauge setup like? Any details? And as for teflon sealant...is it a tape or liquid/glue? I imagine it would have to be resistant to the high temps at the block though eh?

 

just a little tape is what I used I made a pillar for my gauges

 

How do I go about wiring a coolant temp gauge....is it fairly straight forward? Do I tap into that drain on the block somehow?

 

pipe thread dope on a brush or in a tube works fine too, i use this when i install head bolts

always works great


so..

good luck

 

Sorry to bring back a old post but does anyone know what size,pitch,thread the drain plug is? I want to install a aftermarket temp gauge in my 86 but I need to know what adapter to buy.
