Hey guys, long time listener, first time caller. Just curious, I added straight (undiluted) antifreeze to my radiator after replacing the water pump and thermostat.('97 Chevy Express 3500 5.7L) I assumed I would need at least 2 gallons, but I noticed it getting close to the top so I stopped with about 1/8 of the coolant left in the jug. I ended up putting maybe 1-2 cups of water in the radiator before it was full, so I just poured the rest of the water into the resevior, making the mixture in the radiator far from 50/50. My thinking was that the water in the resevoir would circulate through and it would all mix together and everything would be fine. Then I started doubting that theory because the resevior tank is NOT pressurized, so why would it? Is this bad? Will it all eventually mix together?
Or am I just crazy?
Thanks for any and all help!
