antifreeze question

Sometimes, bad things happen when you attempt to open your radiator's drain **** or pull the lower hose - especially as the radiator ages. If you are risk adverse, you can also consider dropping a small hose in the radiator and just syphoning the coolant into a bucket.
Also, if you run with plain water to flush, you may have quite a bit of water left in the system. After draining, I would add more antifreeze than water and test with a hydrometer. If you check your system's cooling capacity in your owner's manual, you can calculate how much antifreeze you need.
p.s. Sorry for the "****" after the word "drain," the site's profanity checker won't allow the name of the radiator drain to appear in a post. I do appreciate the site attempting to keep the posts clean though!

And no, you can't flush it with water and then add a 50/50 mix. It will be too lean.
There will be water remaining in the engine, heater core, and some hoses. You need to take your coolant capacity, and pour half that amount of full-strength coolant into your system. Then top off with water. Make sense?

Gold is only required for extended drain - standard coolant is fine for "normal" change intervals. I've got the green stuff in mine. All you need to do to switch from gold to green is completely flush it out, you can't mix the 2.

I dont plan on removing any freeze plugs. Not ready for that headache if one were to strip.
I believe the capacity is 5.1 gallons. so Im thinking after complete flush adding 2 3/4peak(full strength) and rest distilled water. Do you have to run engine with fill cap off to allow air to escape system and fluid to enter block/heater etc.? or is there an easier way?
