How the hell do you get ALL of the air out of the radiator? I've been trying to bleed the air out of my radiator for 2 days now, and the damn thing just keeps spewing ou all of the coolant I added followed by bursts of air. Whenever a small amount of air comes out, TONS of coolant pours out onto my pulleys and H20 pump. By the time ALL of the air is out, all of my antifreeze will be gone and I'll add some more, it'll get MORE air trapped in the radiator and then it'll overheat. AGAIN.

Why is it such a chore getting this car to run cool?

When I was adding the antifreeze, I opened BOTH bleeder valve screws BEFORE I added the coolant, that way the liquid would flush all of the air out through the bleeders. Well, the only thing that did was nothing. The air is still in there and no matter how long I keep the car running with the screws open, air just continue to flow, and flow, and flow. It won't leave.

I'm gettin pissed, nothing like this happened before. Why now.

 

What I usually do is fill the rad and run it with the bleeders open till just coolant comes out. Top up the reservoir.

Then drive the car for five minutes and then bleed it some more and refill the reservoir.

Repeat until your car doesn't get stupidly hot anymore.

Its a pain in the butt but thats how you do it. Make sure there is plenty of fluid in the reservoir for it to get sucked in when the rad goes dry.

 

I try to park my Formula with the front end on a slope making it higher than the rear. I open only the bleeder on the t-stat housing after I fill the radiator. The radiator level drops when I do this. After I get it to where the coolant level no longer drops and is steadily coming out, I move on to the bleeder on the heater hose. They engineered the cooling system to be gravity bled with the engine off . This is the easiest way that I have found to get it done. Hope this helps.

 

take it to the track and do 3-4 runs. that helped force the bubbles out of mine. runs cooler now.

 

As I recall your supposed to run the car up to normal operating temperature with the rad cap open. You then close the cap and bleed the air out with the bleed screws. If you're already doing that don't rule out that your radiator cap may be broken and leaking air in.

 

I've had to get air bubble out of my coolant system a couple times (water pump install and opti install) both times I never used the bleeder valves. I just topped the rad up, started the car with the cap off and let it run for a bit while keeping and eye on the temp gauge. After a while it goes down a bit then I add more coolant and take it for a rip. The temp starts to go up pretty quick after a while but after some spirited driving and quick turns the gauge just dives. after that I usually park it for about an hour then top it up. After that drive it normally with a bottle of premixed colant in the trunk and keep an eye on the gauge. If all is good then check the level a couple days later and add if needed. That's worked perfectly for me twice.
