when i start up my truck i can hear coolant or water moving around throught the two vents in the center of the dash above the radio! i know this is not normal! what is causing it to do this!:bugeye:

Wtf.....are you positive its comming from there? Still get heat ac, and is your coolant level low?

My truck does that too...you can hear the water moving when the truck is cold...I believe that is normal

 

[CHRISK00S10]

pretty sure! i know it is! heat works fine and so does the a/c! i did have a problem with the coolant bottle staying full and not going back into the radiator but it turned out to be the return line was clogged up so i fixed that! i know it's weird!

 

[CHRISK00S10]

mine does it when it's cold and warmed up! it never did it when i first got it new!

its just water filling the heater core back up or freon reentering the system...... its some what normal.... if it aint spraying on the floor dont worry about it

I've heard this could be caused by a blocked A/C drain...haven't had this myself tho.
