bleeding AIR

is there a bleed valve so i can bleed the air out of my cooling system

As long as the nose of your car isnt facing facing down a steep hill, the radiator cap works very well.

Yeah, you can pretty much just run your car on the flat with the rad cap off for 5 to 10 minutes (depending on how much air is in the system) and it should take care of the waterfalls

you could speed it up by lifting the nose off the ground or pointing up a steepish incline. Cycle the heater on and off as well several times to help "burp" it. I also like to squeeze or wiggle the hoses around the engine bay as well.

If your car is making the water fall sound, and it wasn't doing it before, you now have a leak somewhere.

yeah it sounds like bubbels lol and it over heated on me.

I bleed mine over a few days by making sure the overflow bottle level is kept proper. The heating and cooling cycles will bleed the air out. As the water warms up and expands air gets trapped in the top of the radiator then pushed into the bottle, when the engine cools and the water capacity shrinks back down it sucks back in water from the bottle. Thats what the overflow bottle is for, it just takes a few days to get it all out. Just make sure you run your heater during this process so the air trapped in the heater core gets pumped out.
