Hot water to spill out hose ?

[Dsmj89]

After replacing my upper and lower radiator hoses my car had 0 water leaks. I used only pure water for the meantime to make sure there weren't any leaks and gladly there weren't any. Today i took the car for a spin for a good 20 minutes of driving through my neighborhood and when i parked my car it started leaking water through the hoses where the clamps are connected at, and the engine temp started to rise.
My question is, does running really hot water cause the water to leak out like this through an escape source ?

Running straight water will actually cause the engine to run cooler than it otherwise would running a water/antifreeze mix. So I doubt that has anything to do with the leak.

Did you clean off the necks where the hoses slip onto before installing the new hoses? The corrosion that builds up can sometimes cause a poor seal. I like to use a Scotchbrite pad to clean them up before putting the hoses on.

Also, if you are using the stock spring type hose clamps you can consider switching to worm gear clamps to get a tighter clamp. Just don't over do it.

Thanks for the answer, i do believe strongly what you said about the corrsosion and the poor seal. When i had 50/50 mix of antifreeze it wasn't giving me this issue however.
The necks did have corrosion however, but i did clean them before putting on my new hoses.
I have the worm clamps, the ones you tighten with a flat-head. I will try taking off both hoses, sanding the necks a little to clean it, re-install the hoses and fill in a fresh 50/50 mix of coolant and see how that goes. Thanks for the help romeen.

I agree withs the corosion and worm clamps. However if you run strait water you have a lower boiling piont than if you have the proper amount of coolant. Coolant serves two purposes.

1. Lowers freezing point the higer the ratio of coolant the lower the freezing point.
2. Rasies the boiling point the higer the ratio of coolant the higher the boiling point.

The mimimun recomend ration is 20% coolant and most of the time most people run 50% coolant. Pluss turbo cars run hoter than a N/A car. If you were at the boiling point the water could have fond the easiest way out trough one of those hoses due to a bad seal and over heated ruber.

EDIT: I see you from FL. Down here you have to run coolant or you will just boil out the water especailly on a turbo.

By down here are you referring to louisiana or florida ? What type of temps do you have where you live ?

Does anyone else think or have any other input on this ?
I know running straight water isn't a good idea, when my car had 50/50 coolant it ran cooler and never heated up past normal engine temps.

Make sure your clamps are tight.
Refill your car with at least a 80/20 water/antifreeze mix.

Drive and see if it happens again.

You probably just started to boil the water.

 

[Dsmj89]

Thanks. I'm going to clean the necks down a little more and then make sure i tighten the clamps really tight, and then do the 80/20 or 50/50 mix. Would you recommend water wetter instead ?

Your not too much hoter in Maimi than I am here in Louisiana my temps are equivalent to Orlando and Daytona.

Dang must be pretty hot. I guess i'll just do the 50/50 coolan mix and call it a day. I think i might even bee needing a new radiator soon.
