Hello everybody not sure where I should start but I replaced my thermostat yesterday and refilled the engine with distilled water and anti-freeze. I started it up earlier today to check for leaks about 10-15 minutes idle no problems coolant level good and no leaks. Then drove it about 30 highway miles to work any air bubbles that it may have had when I stopped to look at everything I wiggled the coolant reservoir couldn't see any movement thought I was low. So with coolant temp at 202F I opened the cap and a lot of coolant came out, if I had to guess about 4 gallons and with enough force to cover my hood. After that did the 30 miles back home coolant temps were normal and level stayed the same about 3/4 of the reservoir.

So would a big air bubble cause it to shoot out like it did and since most if not all of the coolant that I put in came out should I be worried? The truck has now been sitting for over an hour and the coolant level is about 1/2 of the reservoir.

I doubt it was 4 gallons man, maybe 1 gallon.....4 gals is over half the capacity. And yeah a big air bubble will do just what you describe if you don't slowly open the cap to relieve the pressure

I wouldn't say slowly but I turned it till I heard hissing then when it stopped I turned it the rest of the way and it bounced off my hood along with a bunch of my coolant like a fire hose for about 1 second. So if a air bubble did it how do I get it out?

Sounds like you already did
Then why didn't my coolant level drop? I filled it to 1/2 then drove it, blew some out and it's still at 1/2.

I'm guessing that you didn't lose nearly as much as it appeared. Spills are like that. The last beer that I spilled was like a million ounces. :)

Drive it for a bit. Let it cool. Release the pressure. Add coolant if necessary. Drive it more. Hard. Let it cool. Repeat as needed.

...and, for heaven's sake, don't ever do what you did again (without videotaping).

Am I the only one that feels the athe OP is incredibly lucky to not have scalded himself. The do not open hot on the cap is no joke. That cap should have hissEd for a solid couple minutes to relieve pressure.

He was lucky, yes. I was guessing that he knows that he was lucky. ...and that anyone else reading this would know it, as well.

I got hit with coolant from my block drain during my ELC swap because I was rushing things. It slowed me back down real quick.

Great post. :hehe: I'm going to use part of it as my new sig quote.:beer:

Same thing happened to me. During one of my drains I had a tube connected to the nipple of the Fumoto valve, when I opened the valve the tube came off and hot distilled water started pouring out everywhere and got on me. I rolled out from under the truck as fast as I could, took a few deep breathes, and told myslef "Let's not let that happen again."

Exactly. It's like we were using the same playbook.

I will say this I wasn't worried about anything coming out because I couldn't see a coolant line (I wish these things were clear) when it popped off some did get on me but to my surprise it didn't burn like what I thought 200F would. A lot more would have gotten on me if I didn't have the sound insulation that diverted it forward and to the passenger side.

After more than 2 hours of sitting I went to top it off and when I undid the cap almost all the coolant in the reservoir drained out so the bubble is starting to work its way out. Also my upper radiator hose sounds like it has some air in it well.... I have a new project for tomorrow now.

To the OP: If you want to do another coolant system repair/flush/refill and don't want to have lifelong scars from 3rd degree burns, get a Uview Airlift system. Works amazingly well and is worth the money. Glad you weren't injured.
