Coolant flush question

[bfar]

Hi all. Just finished a coolant flush and brake pads/rotors change during the weekend! My first "serious" work on any car ... having previously only ever changed the air filter! Feels good.

I had two questions about the coolant flush. I'm still getting the "Check coolant level" message on the car's OBC. I checked my coolant level, and it is above the "MAX|Kalt" mark when the car was at operating temp, and just at that mark when cold.

1) How much torque does the coolant bleed screw need? I have tightened it in all the way. Is this okay, or do I have to keep it only lightly tightened (I dont have a torque wrench).
2) My engine block coolant drain plug had no aluminum washer. Could this be a problem?

Thanks for any feedback!

Cheers.

^^ you need to bleed the cooling system. Best way that always works for me is to put the car on an incline, put the heat on full and open up the bleed screw. then i reach down and manually massage the rad hose going to the engine to make sure all the bubbles are out. As for the bleed screw, since its plastic dont over tighten it cause if you do your ruin it.

If your system is at the proper level and you still get a check coolant error your level sensor may need to be replaced.

first u will need a coolant level sensor on the bottom of the reservoir and u need that alloy seal ring on the block cause it will have a slow leak and open bleed plug poor coolant in it till no bubbles come out from bleed plug whole :) and tighting it snug :) orless she will snap :)
