block plug question

[denwbaseball]

Ok so I know I've been MIA this season but I'm getting ready to winerize and I have a quick question. When I winterized last year one of the block plugs pulled some of the threads out of the block....it took an act of god for me to get that plug back in the block properly. Do you think that I can get away with just pulling one of the plugs? will that get all the water out? Or enough of it out and then adding several gallons of antifreeze?

You need to take both out or only half the block will be drained, did you put them both back in after you winterized or in the spring you had a hard time getting them back in. Put anti sieze on the threads and screw them back in n out so the threads don't corrode over the winter

If the threads are jacked up you could chase it them with an NPT tap to clean them up, then get a new plug to use so you don't chew up your clean threads with a boogered plug.

What I did on mine was install a drain cock valve so I no longer need to remove the plugs. Basically it is a brass "T" that screws into the block, has the drain cock on it and the knock sensor on the end. Its a simple set-up and makes draining the block simple.

Just something you might want to consider. If you need pics let me know, I can post some up.

Fman, where did you pick up the T's or do you have a Lowes part's list? If I recall I only have a knock sensor on the one side.

Thanks,

Dave

I'd like to see that, its a great mod.what size T and where did you get it? Oh and what exactly does the knock sensor do and how does it work? Just googled it ,now i know :)

If you dont want to mess with the plug. A lot of people I know just unhook the raw water inlet hose and stick it in a bucket. And suck up 4 gallons of 100 below marine antifreeze. Personally I drain mine. And then fill with antifreeze. But I have never seen any of them have a problem doing it that way.

Doc I posted a new thread in the "mods" section with a picture. If you have any further questions, please ask!

If the threads are not salvageble, you can repair the threads with a heli-coil.

I've never removed these block plugs.... just pull your thermostat and suck in 4-5 gallons of RV antifreeze..... You'll be good.

I would agree you want to remove all plugs. You might consider the pet cock idea. Another forum suggested using pet cocks with removeable stems to allow you to probe the hole with a wire to ensure you remove any sediment that tries to jam up the hole. The pet cocks suggested were standard parts available from McMaster Carr.
