Coolant change ?
Hello all. Ok so deltas are great within 3 I was just thinking about a drain and fill, can I get away with just pulling the lower hose and draining? And then refilling with 50/50 gold. Or are their more point I will have to drain from? I just read through 36 pages of posts and didn't find a defining answer. Thanks

Not a good idea. After your second or third drain refill with 1/2 the full capacity with straight Ford Gold and then top off with distilled water. You want a 50/50 mix.

Yeah I'm not doing a flush here I just want to do a drain and fill. I have no reason to do a flush So I can just drain and fill up with 4 gal or so of the ford 50/50 mix

Just draining will only remove 1/2 the system capacity that's why Eric and Mike said use distilled water for a "flush". You want to get all the old coolant out. Draining once and filling once with distilled water really won't get all the old out, that's why Mike suggested 2 or 3 "flushes" with distilled. After you drop the last flush you can refill with 3.5 gallons of straight and top off with distilled to have a 50/50 mix.

Yes you can. Fill to the min line and drive to temp. Let it cool over night and then fill again with 50/50 to the min line. May take 1 or 2 times to get all of the air out of the system.

If I just did drop the lower hose one time and drained. Would the 3.5 of straight gold and top off with distilled water still apply or is that only when you have the system full of distilled water from multiple drops

The reason you fill the system with water multiple times is to get all the old coolant out. I usually flush with clean tap water a couple of times then two or three times with distilled. After the last hose drop I refill the system with 3.5 gallons of straight coolant and finish with distilled.
I also remove the thermostat so the liquid goes through the whole system faster. You can do multiple flushes in an hour vs. waiting for the vehicle to have to warm up.

Is it ok to simply put the end of a water hose in the degas bottle and take of the bottom radiator hose off and drain the radiator while water hose inputs tap water into degas bottle while the engine is idling?
