Burping air out of system

[ericem]

Hey guys. I just want to know what is the best way to bleed a turbo car? Am I suppost to leave the rad cap off until the engine warms up and then i can start filling? Last time I just topped it up before the needle got to the middle, and have left it. Could this be why my fans run forever? Going to try this method I guess.

I've never found a good way to bleeding the turbo system. My approach is usually fill it as much as possible, cap it, run it up to temp and let it cool down. Then take the cap off, put more fluid in, and repeat. After several goes it tends to get all the air out.

Yea, leave the evaporator rad cap off and warm the engine up. Until the thermostat opens up, the level won't change. Once it does, you'll know since the level in the evap container will significally drop. Then continue to fill it up with coolant till it's full again. Also make sure the overflow tank has a decent level, since it'll suck more there when things cool down.

Well, just did this, definitely did go down noticeably when the thermostat opened.

Doesn't overheat. Yet, when I idle fans stay on for more then a while. I don't have the patience. There is definitely a problem still. When I touch the gas, I do hear that gurgling noise from the heater core.

This is what happened. There was stop leak added. I found it clogging the tank on the top the bottom fitting, also the thermostat was solid with the crap on it. Everything else seemed fine. Every hose going to the tank on the top I flushed, the rad I flushed, heatcore lines I flushed. Any other ideas of something that could be significantly clogged? How do the cores on the radiator work? Is it one whole piece, or are there seperate cores, and possibly one of them got clogged?!

I feel bad driving the car like this as I am not aware if it is cooling properly.

I just went through this when I did my waterpump last month. What a nightmare. It took me a few tries to actually totally get all air out.

The first time I thought I was all set, but I popped the hood after driving it for a while, and I'm surprised a hose didn't pop off, there was so much pressure in the system. Damn air bubbles.

What really helps, park the car on a hill so the filler cap is higher than the rest of the system to get the bubbles to rise to the top.

I just kept a jug of coolant in the car, and added little by little over the course of 3 or 4 days, and it was fine.

Ya I am going to have to keep trying. Get's so annoying popping the hood everyday lol.

Did you flush the heater core and block? If you can back-flush everything you might get more of that crap out thats clogged in and slowing the flow through the system.

I just take the small hose off the passenger side of the radiator and fill it till fluid comes out the small hose. Hook it up and good to go. Never have had any problem. The air goes out the small hose while you are filling the system and you don't have to mess with doing anything else.

And actually, never use any coolant stop leak in a subbi... if you plug the heater core with the stuff, the T-stat will never open and all coolant flow will be stopped... it's not a pretty picture when that happens.

I had an air bubble on my WRX, we lifted the passenger side of the car and out it came. Its a trick we HAVE to use on the BMW's they are a pain to bleed.

Not really a trick or anything. Just another tool to add to your tool box. Lisle Spill-Free Funnel, just let the vehicle run and keep the funnel filled. It'll bleed the system out when the vehicle warms up. Or if you want, before you install the t-stat in the car. Put a pill, I prefer to use the coated tablets much stronger, in the t-stat to keep it open. The coolant will disolve it away. I think that is all the tricks I know.

I love the dissolving pill idea. It's one to remember ...........ingenious............but simple.I like it!

You just got to make sure to use a coated one. The gel or non-coated ones usually get chopped in half by the thermostat.
