water pushing out of overflow

[hypermaxed]

i just redid the head gasket on the car now there is water pushing out the overflow bottle and it ran fine right after i did the head gasket on it
... now its doing it again it blew 1 hose so i put another one on now its doing it again... i am out of ideas

You replaced the head gasket twice? Which hose blew off? You can do a low cost gas analyses of the coolant for exhaust gases and also a pressure test. This will check for a leaking head/block etc. Does the coolant system need bleeding of air?

[Beemik]

Coolant pressure is equal to about 12-20psi. Is that enough to blow a coolant hose well yes maybe if the extra coolant cant exit the overflow bottle fast enough, but more important is the steam. you should have a small hose on top of the rad that goes to your overflow tank, that is the overflow hose. It main purpose is not to allow extra coolant out of the rad but allow steam out of the rad that is why it's so small. Since steam is expanded liquid when it gets into the overflow tank and cools it turns into liquid again and the excess warm air exits the long drooping hose from the top of the overflow tank. NOW, if that long drooping hose has something stuck in it you could blow the top off your overflow bottle or blow the hose off. If the over flow line from the rad has something stuck in it the pressure will have to go some where. You will likely blow off the overflow hose before you blow a rad hose, but things are possible. If there is too much coolant you will pop the top on the overflow bottle.
Conlusion: check all the overflow hose and overflow hole in the top of the rad make sure there is nothing blocking the steam from escaping. If you have done that and you know there is nothing wrong then start think abut a build up of pressure in your coolant system due to a bad block or gasket.

How did you torque the head bolts?

[hypermaxed]

i torqued the head bolts to 25 and i only redid the gasket once, and after i did it ran perfectly once! i drove it to work with no problems then when to drive home and it blew the hose...

[toyomoho]

Is 25 enough? Are the head bolts installed using a torque setting then turning them 90 degrees and 90 degrees (or however it is described in the manual)?

[RAILZ01]

What condition is your radiator in and how old is it?

[Flashmn]

25 what? Newtonmeters, footpounds?

[hypermaxed]

we did foot pounds and then the 90 90 turns so i am pretty sure we got it right... and the rad looks good... could it be cause i am running without a thermostat?

[Flashmn]

Put the thermostat in NOW. People dont realize that running without a thermostat causes a shitload of problems. Thermostat doesnt just have one duty, it also pressurizes the water in the head.

why would you want to run without a thermostat?

[Donald]

Did you check the head for warpage and cracks when you changed the gasket?

[darcsyde]

you answered your own question could it be cause i am running without a thermostat?

YEP it could be and probably is cuz of it, you should always run with it in don't listen to anyone that tells you it runs better without a thermostat, if that was the case manufactuers wouldn't put them in in the first place

[darcsyde]

i also believe the head bolts need to be torqued down more, i think there pose to be at 40 ftlbs i believe i have to check on that

I second what Donald said. A warped head will still cause a headgasket leak. Should have the radiator cap tested a well. If its opening at the wrong pressure it can cause symptoms similar to a headgasket leak. And the proper head gasket torque is 22 footpounds + 90degrees+another 90 degrees, so if you only went to 25ft/lbs it wasnt nearly enuff.
