heating

Hi guys, So about a couple of months ago I had the radiator blow. Something caused a huge hole in the radiator. Anyway I got that replaced, but because I kept on driving without noticing it sooner I ran the car hot. So eventually I got the head gasket checked and repaired. Its been about about...

So just recently I noticed a hissing sound coming from under the glove box area. It happens every couple of minutes. I dont really mind it or think that it is anything serious, but it scares the hell outta my gf. :lol: just kinda curious what it could be.
