The easy no-tools method:
Pour coolant into the radiator, or if the radiator doesn't have the cap on it, pour the coolant into the pressurized overflow tank. Keep pouring until the fluid stops going down, then start squeezing the radiator hoses and "burp" as many air bubbles out as you can get. Fill the level back up, and then start the vehicle without the pressure cap on it. Now, you can either jack the front of the car up and put it on stands, pull the front up on ramps, or just quickly drive it a few feet to a place that is sloped so that the front of the car is tilted up higher than the rear, like the mouth of your driveway or something. That puts the radiator and expansion tank at the highest point, and air will always bubble up to collect at the highest point. Once you've got the bubbles burped out as much as you can and the front of the vehicle is placed up higher than the rear, start it up and then go put the heat on full blast. Go back out and look for leaks, then top off the coolant level if you need to. Start squeezing the radiator hoses again trying to burp out more air bubbles. Once you've burped out as many as you can at idle, go rev up the engine to 2, 000 rpm for 5-10 seconds and go back out to top off and burp the hoses again. Once that's done, just go back into the cab and hold the engine RPM at 2, 000 until the temperature gauge reads at operating temperature. Now, you can verify that the thermostat is opened up by feeling both upper and lower radiator hoses. If the top is scalding hot and the bottom is cold, it's not opened yet. If they are both very hot, the thermostat is opened up. Give the engine a few more revs while squeezing the hoses a few times without burning yourself, and then top off the coolant level in the radiator and in the overflow tank. Put a new cap on it, and you're done. Radiator pressure caps are like, $5-10. Don't cheap out on it. Just replace it. The system is now bled out, and any air that remains will be burped out by the cap as you drive it and that volume will be replaced by sucking in coolant from the overflow tank when the engine cools back down and the coolant shrinks back down and creates a slight vacuum.

The elevation of the front end is VERY important for FWD vehicles in my experience. I get the front end 1-1.5 feet off the ground above the rear end. I want the radiator or the pressurized expansion tank to be the highest place as I try to bleed it out. All air will seek the highest place in the system, and that means it'll bubble out into the atmosphere like you need it to. 😎👍 DO NOT skip the bleed procedure, and DO NOT call it quits before the thermostat opens up. Many thermostats have a little jiggler bleeder to allow air to escape while it's still closed, but there's still air that will rush out when the thermostat opens and the flow volume picks up a lot. If you drive away before that happens, you'll have a big air bubble still stuck in there.

Btw JT, if you fill and bleed cooling systems regularly, make yourself a vacuum filler and it'll speed up the process a lot. 💪😎

Every video counts bro and opinions might... from my long hard battle with the coolant system I'd fill the funnel first, raise the front on jack stands then open that screw before you start it of course. Wish the v8 on the 5.7's were like this lol.

[brianobrian]

If you ain't got the bleeder screw or a special funnel, just jack up the front of the car while idling with the heater on full blast.. air can find it way through gravity, squeezing the rad hoses while front in air helps too. Works well on fwd cars as well. Just be safe when jacking up car .

The service manual states that the procedure for filling the pentastar cooling system *requires* a vacuum-fill tool otherwise it’s prone to having an air pocket in the system. I use a vacuum fill tool on every coolant job because it’s faster, less likely to have air pockets, and a way to check your work without doing anything extra. If it doesn’t hold a vacuum you know you need to double check everything and tighten that loose hose clamp 😅

[TheCamarokid]

I have a charger when I Revit to high RPMs sometimes coolant comes out of the reservoir hose

[RattyRatson]

use the matco venturi vacuum tool to suck coolant into the system and it also sucks all the air out. ezpz

Im fighting with air in my cooling system too! 82 KID is a Subaru

How are you? Quick question? I have a 2021 Acura ILX, did a radiator drain, and fill, using the same funnel in this video. Burped all the air out, put the cap back on, now I’m only getting heat on Hi? If I adjust to 86, 85, ect…. The heat goes to room temperature basically. Do these newer Acuras need a vacuum, or something different to get heat on all settings? Thanks👍

[Pitserbayk]

Does airpocket cause all the coolant go to reservoir?

[CheeksTX]

I did all this and still can get it to stop burping.... any tips??

[Mark-umhm]

My gauge is always in the middle also.

[dlbracer]

Don't forget the heater core, too.

[anthony]

My bleeder screw is completely stripped. Exactly like the one you have. What do I do.

[arneichiagreen]

Can you give me advice on my 2014 chevrolet malibu lt.

[nickgustafson]

If that 4.7 didn’t drop valve seats from overheating, then the owner got real lucky

[fainjohnson]

The old school way is just run it with the radiator cap off until it stops bubbling with the heat on and keep adding water.

[zimmer]

How would I bleed the coolant system if my climate control doesn’t work to turn on the heater?

[hectordeleon]

How long can you run a car that’s overheating and it still be ok? I bought an 05 xterra with a blown radiator. It runs really good, it just overheats. Is it toast after overheating a few times?

[ASEWorldClassTech]

Just use a Coolant Air Lift. It will pull all the air out in less time that letting the thermostat open to burp.

I have a 2007 dodge charger SRT it requires 0w40 oil it has 250, 000 miles on it should i stick with the recommend 0w40 or switch to a thicker oil? Will a thicker oil damage the engine? Please Help!!!
