the puddle is running down the drivers side of the car forming 2 streaks between the driver side tire it also get small going to the passenger side. making you think its coming from the pulley side of the engine. but everrything has been replaced annd the same problem

you cant up load from your pc to the site, it wont work. pics need to be hosted on line some place. then linked here.

you can rent a pressure tester at the parts store, free rental really. it goes on as the rad cap, you then pump it up to 16 psi and look for the leak/

[Biggwinn]

yeah according to the radiator shop theyput a preesure test on it but could find the leak because it wouldnt leak bad. they should have put it on the rack to look under the car

here is a pic

[Scottydoggs]

you made it to small to get it to up load to the site, no idea what im looking at there. host it else where on the net.

are you talking about the coolant elbow o rings?

[markpa]

No. The heater hose connections to the alternator bracket are a loose fitting connection with o rings.

Mine was just leaking out of the blue. So that's why I mentioned. Pics or video would help
