Bleeding air

Hey guys, ive heard alot about bleeding air out of ur coolant system and entire system, and it could fix problems like low coolant light, overheating etc. How exactly do u do this? is it easy? im not a mechanic but if its simple enuf i can do it. Specifics would be great, pics even better. Thanks alot guys.

Hey guys, can someone help me with this please? Also is it hard to bleed the air in the brakes?

I was wondering what that green cap is on one of the hoses or w/e, it has a little sticker on it saying 1psi max, service port or something, tighten hand tight only. I opened the cap and it looks like some kind of valve or something, what is that? Anyways help wud be greatly appreciated. Thanks

there is a nifty tool for your antifreeze. You can buy one i think it is around $100 or go to dobbs or something like that and have them do it. all it does is sucks all the air and fluid out of the system and then the colant goes back in with pressure behind it. works pretty good

The tool that he is talking about is probably this one (http://www.mityvac.com/pages/products_cse.asp). They are on eBay occasionally new and used. There is on on there now for $45.

I can't say for all Cavaliers, but on my '97, the tank is the highest part of the system and air bubbles would normally just work themselves up to there. There is also a bleeder screw either on the bypass pipe or on the thermostat housing used to vent any trapped air in that portion of the system as well.

yea that is the tool a cheaper one. i wish i had the luck of air bubbles comming to the top of my system lol

Ok thanks, is that bypass pipe the thin one coming from the coolant tank?

Anybody? Where is the bypass pipe and bleeder screw like you said?

The green cap with the valve on one of your lines, I believe is to recharge your airconditioning.

You don't need any of that crap, just drive it around and check the coolant for a few days.

CDRU was right, the coolant tank is the highest part of the cooling system, the air bubbles will find their way there and head out through the top.

Those tools are for folks who service someone else's coolant and need to make sure its good to go when they leave the service location.
