When i did this on sunday, the bleeder on the thermo cover was open until coolant came out, but the other one when i opened it, nothing would come out and the coolant would volcano out of the radiator, is this normal?

 

You did bleed it with the radiator cap in place right?

 

It's my understanding that one of the bleed valves will expell air/water while the other one actually sucks air in

Maybe someone else can elaborate for ya .....

be care full useing the bleed screws make sure nothing can drip on to your opti. guess how I figured that out after the third opti in less then 6k miles.

 

Yeah, I put paper towels under the valves so the coolant would have something to catch it. I did get all of the air out. You bleed the one on the thermo cover with the radiator cap off, and the other with it on.

 

The paper towell trick is the key for sure.

The service manual procedure says to bleed with the cap open, engine running, but I stopped doing that after 2 "volcanoes"

I have great luck bleeding with the cap off, and engine not running yet. Just fill to the top, open the bleeder (either), and leave it open until you hear the air STOP rushing out. This should bring the water level down a little. Repeat until the water STOPS going down, replace the cap, and then do it with the engine running (CAP ON). Drive a day or so, and check the level for the next few days.

Good Luck

I took me more than 2 "volcanoes" to learn to shut the motor off. But I did catch a clue. I got all of the air out. But my low coolant light is still on, so i am assuming that the sensor is bad. What causes it to go bad? It worked until i replaced my radiator.

 

They always go out. I don't even bother anymore. I just unplug the ****. As long as you know you have coolant, you don't need the sensor. Trust me...anyone on this board will know when they don't have enough coolant. No offense women, but only some wives here on the board have no clue when the oil or coolant is gone or if they even have a flat.

 

Aint that the truth.
