Anybody used teflon tape on the block drain plug? Will there be any problem if I use teflon tape on the plug?


You can, none present to begin with.

does yours leak?
 
Medtro,

Can you post a pic of the leak?

isn't it brass? should seal nicely with the steel block?
be careful with tape, it it gets in you could get trouble...

Medtro,

The torque spec is something around 20 ft/lbs if I recall. Don't crank it down since it's a brass plug and will easily break with too much torque.

I'm in the same boat...

Couldn't get the block drain-cock loose this weekend, so I pulled the entire plug to drain the block. Cleaned the plug and got the drain-cock loose and reinstalled the plug to as tight as I was willing to go with the brass fitting.

Now I've got a slight leak...perhaps I should re-tighten when the block is warm?

I did pick up some Locktite high-temp thread sealer if that doesn't work...anyone see any problems?

what's this block drain cock? where is it?

Slightly different question ... anyone know the size of the block drain plug shaft, not the size of the top (14mm) but the size and number of the threads? I'm thinking about getting an adaptor that would thread in there and allow a length of hose to connect to so that one could completely collect what is flushed through. If possible this would make flushing the block that much cleaner and safer from an environmental and animal perspective. Hell if there was such an adaptor, you could flush to your heart's content by using the shop sink faucet for the water supply and the shop sink drain for the returned and flushed coolant / water/ sludge. I guess there is the chance that with whatever works adaptor wise, that open area once an adaptor is threaded through would be so constricted so as not to allow much flow from there? Any thoughts? :cheers:
 
is ha been a wile since I flushed my cruiser but I thought the plug was straight thread with a conical seat as the sealing surface, the threads are not meant to seal, sealing straight threads with tape is not reliable, might want to look at and clean the seat of the plug and block. maybe a new plug?

Hltoppr, do some trucks have a drain cock in the block? mine does not just the plug, could someone have added it?

turbo, when I drained the block I tried to catch it in a pan still some got on the ground as it sprays everywhere, I rinsed it away with the hose to dilute it and ran it into the back yeard, Ethelene glycol breaks down pretty quickly by bacteria (into suar or alcohol cant remember witch) and in small ammounts well dilluted has a very sort enviornmental effect (days) as long as it is kept way from animals until it breaks down,

What happens to ethylene glycol and propylene glycol when they enter the environment?

* Neither compound is likely to exist in large amounts in air.
* About half of the compounds that enter the air will break down in 24-50 hours.
* Both compounds break down within several days to a week in water and soil.

so I would not get to worried about it, catch what you can and dillute the rest, try to get it into the ground where it will be safe from pets instead of running down the street

turbo,

Photoman made an adapter for his 1st gen water temp sensor. It appears the pictures have been lost and I cannot find the thread. He references it here but that link no longer works.

His post says the block drain plug threads are 1.25 X 12 mm.
