I woke up today to go to work, and turned on the car to be surprised by the coolant buzzer. After checking a couple things out, and doing the coolant gargle test the car started warming up thats when I saw the coolant leaking out from what I presume to be the pressure chamber? vacuum chamber?

here is a picture... ( the white circle is where the part cracked )



the black box cracked, and for the life of me I cant find it anywhere online to replace. If anyone can please help me I would really appreciate it.

Thank you very much. Is the petit one known to be good quality, worth buying?

 

I would say, anything other than the stock plastic piece is worth buying.

 

yup, thats the AST. for educational purposes read up on AST elimination and realibilty modifications =]

 

The man wouldn't tell you so if it wasn't..... take the advice and call them. Also -don't drive the car unless you want to buy a motor on top of that AST.



Later

 

Yeah, I just let it sit until the part comes in. Can anyone explain what the AST does? Besides the obvious

 

It's there to help remove air from the cooling system.

 

FD AST= human body Appendix. Each can live without it with no ill effects
