ok guys every time i start my truck it sounds like there is water in my dash please tell me what this is and how to fix it. Thank you

 

Please describe a little more detail? Is it a bubbling or gurgling sound coming from under the glovebox? If so then you have air in you coolant line and it found its way to the highest point in the cooling system, your heater core (stupid design, but that has been hashed many of times.) Search under air in coolant for the different methods to get rid of it and some more info on the causes. If this isn't your sound, please give us some more details.

 

Air in the coolant system. I had this for the longest time and thought it was normal as others told me they had it as well. Even after having a new water pump and T-stat and the system flushed it still did it. I ended up just checking it one day and the radiator was full I did have to add a little to the resivor and now it no longer does it. They say pull it up to a hill and start it then watch it and add as needed.

I did open my cap when it was a hot and tiny bit came out after I got it back from getting all that stuff done to it so maybe that let air in the system idk but it no longer does it.

 

Mine does that too when it's low on coolant. Add some and it should go away. Don't just rely on the reservoir, though, check the radiator to make sure it is full and there aren't any air pockets.

 

Like the others said its air in your system. Park up on an incline, remove the radiator cap and let it run for 10-15 mins, add fluid if necessary. While running also squeze the upper radiator hose, helps the air escape.
