      im about to change the t-stat and radiator hoses, i just read that hafter u do that you gotta burp the air out of the system, how do i do that? i read that u just let it get warm then refill it then put that cap back on, does that mean u let it get warm without the cap on? maybe im just reading it wrong but thats what it sounds like, thanks for the help

      Yes, without the red cap

      Fill it up. Leae the cp off. Run the engine until the t-stat opens. You can tell when it does by the flow back into the rad. will be warm. Let run like that for a minute or so. then add water (not ice water;) ) until full. Let it run a little bit until you're sure it is going to saty at level. Then put rad cap back on. Be sure to refill your overflow also.

      Yeah I found that putting the pipe back on to be the biggest pain in the butt. I believe mine held 4-5 gallons? I don't really remember anyone else know for sure.
