This instructable will walk you through the simple process of "burping" or getting all of the trapped air out of your cars cooling system. This works for ALL Vehicles

If you have had any parts replaced on your cars cooling system (radiator, waterpump, new hoses, ect) then there is a chance that your cooling system has air trapped in it and this could make your cars cooling system operate poorly, or in worst cases minic the symptoms of a cracked  head.

So BEFORE you spend thousands of dollars at the mechanics having this done, try this and see if your cooling system operates normal (temp stays within normal , does not get hot or overheat).

Step 1: Things you will need

AnitFreeze or Dex cool, I used the 50/50 water dexcool mix

Spill free funnel ($20.00 on Amazon.com)

Rag to wipe area clean

Time and Patience
I have a 2002 Chrysler Concorde. I tried using the bleeder for the coolant air. But I must have did something wrong. Because now all I get out of the bleeder is straight Steam air. I did this for about 5 minutes nothing but steam coming from the bleeder. What do you suggest?
check to see if you have enough coolant in your radiator when it is cold, the try burping your system Like I have shown here
I was trying to help husband cus he hasnt had time to change the thermostat so I did it. I thought it would be simple but now I think I might have bubbles cus I draied the coolant and added coolant back after and now the temp just keeps going way too high (up to 248). Would this method work for me? Its an 07 Cobalt. Please help!
this should work for you, as when you drain/refill the system it puts air back into your system,, the air presses against the thermostat (new or not) and it has a hard time opening when it should did you also have you temp sending sensor replaced? if not it should be f it is a few years old. I like to drill a VERY SMALL HOLE in my thermostat , using the smallest drill bit that I have it ends up breaking the bit because it it so small) this is to allow the air that is on the engine side a way to go past the T-Stat. Yes your car has a bleed screw, but when your T-stat is closed and the air is on the other side that bleed screw does you no good. burp the system, if that solves the problem , good , if not change the temp sending unit as well
My 06 equinox is running cold. I just did the head gaskets and no problem there. Do I have to burp the coolant system?
cold huh? normally your car would run hot if it needs burping due to the thermostat not opening like it should... did you check to see if your thermostat is stuck open? that could cause it to run cold.
Thanks for posting this used it today on my 08 grand prix worked excellent.
your welcome.... just did this again last week as I replaced this cars thermostat, temp sending unit, and the pigtail/harness that plugs into the sensor.
Despite all the complaints about DexCool coolant, I have never had an issue. It may have been reformulated or gasket materials may have been adopted to it. I have 252,000 miles on my 2004 Chevy Venture and have had zero issues with DexCool. I am rebuilding a 2004 Caravan 3.3l with 172,000 and I see absolutely zero damage to the internals, gaskets, aluminum and iron coolant galleys, and anything that the DexCool coolant ran through. It is apparently less acidic than standard coolant. My understanding is that some vehicle owners may add the standard green coolant to the DexCool and create a sludge like mix which causes potential issues. I did read the complaints and about the lawsuit, however, I have had no problems. I choose to run green coolant in my other vehicles due to price and I perform regular maintenance.
Hi there, I have some comments for your Instructable: <br> <br>1) I don't like DEXCOOL at all! To see why, just search for it in Internet, and soon you will start to see that it is frequently dubbed &quot;DeathCool&quot;. GM decided to order Texaco a new (then) coolant formula. Those guys developed one that produced a lot of problems; you will read about gelled coolant, damaged intake manifold gaskets, totally ruined engines and thousands of legal demands and Class Action Suites! <br>I suggest that first you find the kind of coolant that the engine needs, then get a recognized brand. I use Chrysler's own &quot;Long Life&quot; formula with very good results. Today, coolant formulas come in several colors (but sometimes color is not entirely representative of the type of chemistry of the coolant). but if engine has Aluminum, iron and other metals components, a &quot;Long&quot; or &quot;Extended&quot; life type of coolant is most probably the best bet. Be aware that even when the container says something like &quot;5-Year&quot; formula, after the first change, it will NOT endure for so long, because now the engine will have some corrosion, therefore the replaced coolant won't last as long as when the engine was brand new, so a more frequent replacement is desirable. I do it every 3 years when using the Chrysler &quot;5-Year&quot; formula, toghether with a complete flush, back-flush and complete hose and belt exchange. in that way, my cars are as reliable as possible regarding cooling system performance. <br>2) Coolant is made with Ehylene-Glycol as its main constituent, and this chemical EATS most factory paints right away!, thus, if ANY spill occurs over any painted surface, you will need to have PLENTY of clean water at hand to wash and quickly dilute the spilled coolant. Your Instructable says: &quot;have a rag to wipe any coolant off of your car&quot;, that is not enough, and can get some paint damaged. <br>3) Modern (say, after 1990 engines) do get to proper operating temperature in much less than an hour if the ambient temp is not too cold outside, therefore, after starting, about 15 minutes of idle is enough if the thermostat is in good working order. <br>Best wishes.

<p>Never heard that anti-freeze will eat auto paint. I tried googling this and couldn't find anything. Are you sure that you weren't thinking of brake fluid?</p>
<em><strong>BOTH</strong></em> Brake fluid <em><strong>and</strong></em> Coolant have the same type of main component: Ethylene Glycol (or other glycols). These chemical compounds can dissolve the clear coat and continue to damage the color coat too. The only difference is that Brake fluid is almost 100% concentrated, and coolant solution has only about 70% or less concentration of the glycol. Therefore both can damage the paint, only that the brake fluid will do it sooner and harder...<br> <br> In case of spillage, best get some water and quickly wash the paint WITHOUTtouching or &nbsp;wiping it, as if the fluid has already started to attack the paint, any wiping will remove th top pf the coat and the damage will be worse! &nbsp;The sooner the fluid is diluted, the less chance of ruining the paint.
<p>good advice, if this was a new car I would have done that, but this car is now 11 years old and I just try to do basic preventative maint on it to keep it running it top shape.</p>
a few years ago i screwed the pooch and blew my head gasket trying to backflush and burp.
<p>yeah I do not black flush for that very same reaosn, just burping is good enough for me </p>
<p>this is kinda cool cuz the instructions arent too overloading.im a pretty inpatient woman lol</p>
<p>glad I could help!</p><p> it is also a good practice to get a VERY SMALL drill bit and drill a hole in the thermostat, the very small hole is just used for any air that is trapped in the engine side of they system to escape. Yes a little coolant will leak out of the hole, but that is why you make the hole as small as possible so it will not effect your system at all. Using the bleed screw in newer cars only lets some of the air on the radiator side of the system out when the thermostat is closed and will not get all of the air out. </p><p>where you drill the hole on the thermostat depends on if the thermostat is placed vertical or horizontal in your car.... but that is for another instructable :)</p>
