'95 fluid change: Coolant & freeze plugs problem

Use a box end wrench with the hex to gain leverage. What comes next is similar to being under a large waterfall. My weapon of choice is a 2 ft section of rad hose that I jam up to the opening ASAP and point into a bucket. Even then it can be a mess.

 

I am able to get the socket in there. I guess it depends on how long the bit is with the socket. I use a flexible handle 3/8 ratchet to break it loose.

 

Those are not freeze plugs, they are drain plugs. Aluminum motors do not have freeze plugs.

 

Well they were wrong. Let not be wrong too, familiar or not.

 

When I drained mine I would guess about 1/2 to 3/4 of a litre on each side

 

Ok I got to know, why don't aluminum engines have freeze plugs?

 

Possibly because they are die-cast? "Freeze plugs" are actually used in sand casting to remove the core sand from inside the engine passages after the iron cooled and before machining. I think they got their name because they would push out if an engine didn't have enough antifreeze and and the water passages froze in cold weather.

 

Aren't these engines sand cast as well? I agree with why they are called freeze plugs, but with that logic you'd think they would have that in aluminum blocks as well.

 

I agree that I would say as well the blocks should be sand cast and you need to get the core sand out from those larger holes. I think the confusion from the original intent of this thread is the small plug in each side of the block used to drain coolent from the block was referred to as a "freeze plug" which clearly it is not but rather used to drain the block. I think things went off track due to semantics.

 

What are freeze plugs for?

To pop out maybe when it gets too cold and the coolant freezes?


Just how would that work with a screw in plug? How will it pop out?

Aluminum motors expand too much for a pressed in plug to ever hope to stay in.

If you really want to call a crankshaft a trailer hitch thats fine but there will be 2 problems. No one you know will understand you and half of them will just think you are illiterate.

 

Brian looks like your reading comprehension is beginning to fade. As I pointed out above they are used to clear core sand on an iron block and are mis-named because they do pop on an iron block engine that freezes but they do nothing to save the block from freezing.

 

Clyde you m9ght want to try these
They worked good on mine

You betcha
I sure like them but they are still hard to get to without pulling headers
