Coolant coming out the overflow hose

[hoffman199]

today my truck decided to dump all its coolant out the over flow hose at the top of the coolant tank. Not sure what this means.... I have changed the cap twice and pressure tested the system and caps and all seems to be good. guys at the stealership say that it could be the thermostats, does that sound right or do i have bigger problems. Any help would be greatly appreciated.

I just hand the same problem, and from doing alot of reading, its probably your head gaskets.

I was getting that same feeling too but how do I know for sure its the head gasket before I tear the motor apart?

 

[Tayler]

Have the radiator cap off while it's running, if you can see bubbles, its a good indication that it is your head gaskets.

If it is spitting coolant out of the overflow while idling then it's the cap or the head gaskets. Make sure it's warm enough for the t stat to be open too when yu check this.
