  • ac drier and throttle body questions

    Hey guys, two questions, I just replaced the drier on my ac because the old one was leaking at the port where you fill it up.

    1. I installed the new drier and filled the system with 134a, I went out and checked the hoses for leaks, and I took the cap off the port and i heard some pressure come out as I was unscrewing the cap, and I saw some green dye behind the cap. Put the cap back on and took it off 5 min later, and heard the pressure come out again, but a lot less than before. I saw that the cap had a small gasket inside, which my old one did not, so im wondering if it is normal for it to leak a bit from there? If it isnt suppose to leak from there at all, I dont really see a reason to have a gasket.

    2. My car has always drank a bit of coolant ever since I got it, and when I was messing with the ac I started the car, and tried to look for the "marble in a blender" noise that I have had for a long time coming from the front of the engine. I figured it was one of the accessories, but I took my air filter off of the car when running, and it sounded almost like a gurgling sound, think of when you are drinking through a straw and run out of drink.

    Im wondering if the throttle body gasket went bad and is leaking coolant into the engine from there? any thoughts on that one? I unplugged a vacuum line from the tb and the sound stopped completely for a few seconds before it started again

    1) not exactly "normal" but those valves are notorious for leaking. could try replacing it (if possible) but keeping the cap on it, will definitely help

      its not possible, its welded on, the only thing that may be replaceable is the actual part that holds the freon in, im not sure what its called, but ill call it the valve stem
