Why isn't air bleeding necessary on automotive radiators? - Page 2

post #11 of 39

Mostly because the cooling loops have been designed by people with half a brain so they are for the most part self-bleeding.

 

I mean, look at my computer. I have a big frickin' radiator right on top of the case and the ports facing downwards - of course it takes ages to bleed.

Where is this "bleeder valve" on Fords located? It's not on the radiator, it's not in the expansion tank so where is it?

8051: Depends on the model and what year you are talking about. Some cars has the bleeder around the thermostat housing or somewhere high in the water loop. Watch for a brass screw since that is what manufacturers normaly use. On several cars like BMW there is an "easy" way to see if you have gotten the air out and that is to run the engine temps up, turn the heater on in your car.
If it blows out cold air or just alittle hot then its a good sign you have air trapped inside. But alot of BMW cars has the bleeder valve at the heater radiator. Can be a pain in the ass to get to it sozo.gif

Another way to "bleed" the car is ofc to try and place or tilt your car so the point at where you fill the water in is the highest point. Start the car and let it idle until the thermostat open and water starts rushing into the system. Refill and find the lowest thick watertube on your radiator and press it with you hand hard. And just keep pumping it. If that does not help, you need to find the bleeder valve.

My Hummer H1 has to be bled of air after a coolant change.. first from two separate bleeder valves, and then the surge tank.. then repeat again.

I've never seen such a thing as a "bleeder valve" on any of the Fords I've ever owned -- or my Jeep Cherokee.

Depends on the car.

On the Gen2 SBC, the LT1, there are multiple bleeder screws and due to reverse flow cooling are notoriously difficult to bleed. The waterpump cools the cylinder heads before the block, and its easy to get air trapped in the system.

Yes many newer cars have bleeder valves, this has been around since the car manufactures designed reverse flow cooling systems. Since pushing the coolant down from the heads is for one better cooling but the side effects are air locks hence why they now have bleeders valves..

As said already cars are using a larger loop so a small amount of air in the system really won't be noticed also they are open to vent air through the over flow, most PC water cooling systems are sealed to prevent leaks and spillage. PCs also have a lot of smaller tighter places for air to get trapped.

But a properly and not overly complex system. (lots of blocks and tubing) should be real easy to get air out of..

If you bleed automotive vehicles you should then know that it depends on the highest point in the vehicle. In my vehicle the overflow tank is the highest so i do not need to bleed. But some cars it is not the highest point which means they must unscrew the bleeder valve on the thermostat.

Most fords often dont have bleeder valves cause imo they are to cheap to do so sadly... You normaly have to "burp" fords... And there is a difference on some models depending if you have an US or EU model.

Not true, it's just they use the overflow tank. I own the Australian Ford Falcon XR6. Not having a bleeder valve is a very poor way to call a company out. They literally self bleed which is BETTER for the end user. wink.gif
