Bubbling noise from exhaust while truck is parked.

When I turn my truck on, and it’s parked you can hear like a bubbling/girggle coming from exhaust or under truck can’t determine where it is cuz I haven’t gotten under it to take a look but wanted to know if anyone else has had this happen and know what it might be. Thanks

 

First thing that comes to mind is low coolant . It is possible to hear coolant flowing through your heater core and more so when the fluid gets low .

Another possibilty is the exhaust rubbing up against the frame

It is alittle low like an inch, is that the cause?

 

Bong?

I think your truck's a druggie.

 

Go buy some anti freeze , top off the level and see if your bubbling is still present . If you are low , you need coolant .
I cant tell you if it will fix the sound because I cant hear the bubbling .
The suggestion I made is only a suggestion using your explanation of the problem

Does it sound like water or air? Possible exhaust leak?

 

It sounds like air not a liquid sound, thank you Gearcruncher
