You can also get a coolant test. Cost about $30 and it will also tell you if you have a blown head gasket.

You can buy that autozone right

I wasted a lot of time screwing around trying to find out why it was overheating and where the coolant was going. I just got so frustrated when I had the same situation and I just took it to a mechanic. He did the test and sure enough, blown head gasket.

Did you take the plugs out when you did this pressure test? Then rotate the engine to see if any coolant may have been in the cylinders?

93z28ltone

No I didn't

You need to do that. Keep the system pressurized for several hours. Take the plugs out and rotate the engine by hand. Make sure to look very carefully everywhere coolant passes. Just the slightest amount of moisture can mean it is leaking and if the coolant is hot then it'll evaporate before you ever notice. Did you check all the radiator seams?

yes i did i spent a hour and half checking around the hoses and raidiator im about to give up and take it to a shop and see if they can tell me what it is
