how do you spell "gurgling"?

Anyway, for a while now I have been hearing the water gurgling in the truck probably from under the dash. you hear it mostly when you start the truck and when you shut it off. I dont see any problems from it but I was wondering what is causing it.

Do I need to add water to the system or is there air in the system?

 

all I hear is crickets

 

I have that too. Not often at all. Sounds like something is draining. Very very intermittent.

 

- Yea, it needs to be bled is all. It wasn't filled correctly at some point. Here's the procedure -



Your going to have to take the T-stat housing loose after your heater core line is disconnected, - to expel that air.

 

I have that gurgle noise too...so i take the heat core hose loose the n the T stat, di i have to start it at all or does the air just come out?....thanks
