I did not use/need a petcock. I remove my antifreeze by 1. The old way - disconnect bottom hose with bucket under. 2. now I use a vac pump with a catch can and just suck it out. If you have a compressor, you can get a venturi vac device from harbor freight for $10 that works great (just is a bit noisy) and once you get flow going you really dont need the vac if the container is on the ground. This set up works well for other liquids like trany fluid etc. Click here for pic of vac pump : http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=3952

Hey its not just the universal ones that are missing the petcock. My 4 core rad (looks factory to me...maybe its not however:confused: ) doesnt have them either. What I do is open the petcocks on either side of my motor (down near the oilpan about mid way from the front of the motor) and when they stop draining I pull the lower rad hose to finish it...not super convient but it works:)

I think you have to special order the drain plug hole to get that. I haven't seen a radiator with a drain in a long time but Griffin is just down the road and everyone locally runs them. RM

You can also pressurize the radiator kind the same way as above to get the flow started. I use a piece of 1/2 aluminum linein candy cane shape with a hose on the end. You put that down in the radiator and seal around it and a blow nozzel at the top with a rag. Allow a small amount of pressure into the radiator and anti-freeze will come out the line. It will start a ciphining on the line and drain the radiator in no time.

I added a 1/4" alum bung (Summit-Jegs) for the petcock. If you don't have the means to weld this I'm sure a local shop would do this for a minimum
charge. It's a pretty thick tank, so the welding isn't to tricky. If you go
this route the last couple treads on the rad side of the bung may have to
be ground slightly to let the petcock close properly, so check before
welding.

I've got petcock drains in my block like 69NovaSS. A bit messy but it works.

I have that same Summit radiator and I was kind of pissed when I had to drain it a few weeks ago before pulling the motor. I've thought about taking it to a radiator shop to add a petcock, but it really wasn't that bad to siphon the fluid out. Just make sure you use a clear hose that is PLENTY long so you can see the fluid coming, which I didn't do the first time. :eek: :mad: Yuck!

how to drain a summit radiator in 8 steps:

1. remove shirt
2. remove pants
3. put on swim shorts
4. place goggles and snorkel on head
5. remove lower radiator hose
6. dry off with old towel
7. throw swim shorts away
8. clean goggles

nothing like an antifreeze bath to cool off on a summer day. just don't go for a drive first...:D
