Hello i just pulled out my old AST and ordered a Pettit aluminum AST..... Just wondered how will i install this sucka!!!!! Thanks alot

 

Just install it like the stock AST, it fits in the same way. They are essentially identical, only the Pettit one has a different shape. My main recommendation is take out the battery to do it, makes it a lot easier.

 

Found this when searching and need to bring it up again. I will be installing my Pettit AST and was wondering if it simple, plus, do I need to drain coolant? Or only what is in the AST?

 

So does anyone feel like answering this simple question in 30 seconds????

 

It's simple. You don't need to drain the coolant, but whatever's in the AST will come pouring. Also, one of the hoses will want to keep dribbling if you let it get lower than it's entry point.
