was it in the block or a loose hose?

 

Thanks a lot for the reply. It was in the block. Thanks.

 

I have no clue what would have pressure other than the radiator. or maybe the freon, but thats not on the block on the bottom.

 

Thanks. It was located kind of under the radiator. The thing I mssed with was right near where you drain oil and coolant. When i unscrewd the "pin" though, no liquid came out... just chemical pressurized vapor. I guess it has to be either coolant or a/c refrigerant. After it happened I did test the a/c and it seemed to blow pretty cold air, but its been awhile since I used it - not sure if it was cold as its supposed to be. And after I drove around for awhile I checked my coolant level and everything seemed ok. nothings leaking or anything. maybe i just let out some pressurized coolant.

 

your lucky.. if that had been me ****ing around under the hood the whole car would have self destructed the minute i hit 20 in it..
