1998 auto .
the "check coolant light comes on , and the coolant is gone.
i drive and then like magic the coolant is right below the fill line.
got to be more than the hot engine bringing the collant back up.
and then sometimes the coolant is fine when cold.
any ideas ?
thanks
Possibly air in your cooling system?

As previous poster has said, most likely an air bubble. Just installed a
new radiator in my 97, so here is how I bled it.
1. Fill to Kalt line with engine cold.
2. Start engine and warm to normal temp – either at idle or go around
block
3. Remove *both* filler cap and air-bleed screw on top of reservoir.
*Be careful* – release the pressure slowly. Coolant should not spill
out, or anything *unless* you have some *real problem*. Safest way is
simply idle from cold engine with both filler cap and air-bleed off,
while adding coolant as necessary when the thermostat starts to open and
sucks from the reservoir.
4. Slowly pour in coolant *above* Kalt line until *no* bubbles come from
air-bleed.
This step is important. You cannot get the air out until you fill it
almost to the top. Go slowly, and carefully watch the air-bleed. When
you are done, you should see coolant present at the hole, and no bubbles.
5. Install filler cap and tighten air-bleed screw firmly enough to seal
the O-ring.
6. Shut the engine off (or go for a drive now) After engine cools down
(overnite) the coolant level should essentially be at the Kalt level.
Hope that helps.
