Question popping and hissing

My wife's cruiser was idling and started to make a pop sound followed by a hissing from the engine compartment. It continued doing this every few moments. It sounds like it is coming from the passenger side of the engine, not sure because I had to leave for work and couldn't dig into it. I don't know what I'm looking for. can anyone help.

Default Re: popping and hissing

Hissing could be from the compressor when it's overcharged from being overheated. Do you see any smoke/steam coming from the engine. The compressor has a relief valve but it's pointing towards the ground. Try running around without the A/C on or even the defogger towards the front windshield because that also turns the compressor on.

thanks for your advice. the defrost was on, so the a/c also. there was a fog/mist with a smell in the garage. thinking back it does remind me of freon. if it is a relieve valve on the compressor, why is it happening? is it an indication my compressor is going bad, or something else?

Most of the time when that happens, it's the radiator fan not working properly to keep everything cool.

Thanks again for your assistance. the radiator fan makes perfect since. I'll check it out in the morning.
