I was hauling concrete pavers yesterday in the back of my van, and only went two miles, and when I got home I backed in and noticed a hissing sound. I turned off the engine because I thought it was a leaking tire. It stopped so I turned the engine back on to finish backing in, then there was a pop like a balloon. There were no fluid leaks, or engine light. Any idea?

 

Was the hissing coming from the front or rear of the van? What year is the van, type of van and what engine does it have?

 

2009 6 cyl 3. Something and it sounded like the front if not just under the vehicle

 

is the a.c still working?

 

Yeah. It was the strangest thing. I even checked the spare.
