Coolant leak?!
Here is where it gets strange and this is the first time it happened. Last night I took the car out and was driving quite aggressively. I parked the car and shut it off when I got home and was outside talking on the phone and I hear a quick tssss sound like water dripped on to my header and eveporated. It did this 2 or 3 more times about every 30 to 45 seconds and it sounds like its coming from the passenger side. Ofcourse I cannot see where its coming from though. Any ideas what is on that side that may be leaking?...i am hoping its not a head gasket or a cracked block....
But, you have the heater hoses that run along the passenger side, one of them could have a pinhole leak. I'd say put the front end up on ramps AFTER the engine is at operating temp. Then turn the engine off and wait a good 20 minutes as the pressure in the cooling systems slowly rises and pushes coolant out wherever this little slow leak is.
