Bubbling from expansion tank.
Bubbling from expansion tank, help.
Hi and sorry to bother you all with my car. Just bought it very cheap, and im not that good at cars 😄
When i got back from a ride and open to look at the coolant level, its under minimum and bubbling alot.
Things ive done is:
*smelled the CAP and tank = no gas smelled.
*no white smoke from exhaustpipe.
Going to do:
*Change thermostat tomorrow.
*Locate the leakage
*Flush the heatercore
*Bleed out air if any.
So what can i do more ?

Update: I filled up the expansion tank again and drove about 10km and checked again, but no bubbles this time. Sooo....can it just be air inside the system ? And it spits out back into the tank and out in the small plastic pipe on the backside of the tank ?

"Update 2: Changed the thermostat, the old one was not that bad, and the coolanfluid was fine to.
Filled up again and turned on the engine, full fan and max temp....temperature was rising to 90degrees but still no heat...i drove home and i opened the hood, and the expansiontank was pressing out condensed air like hell from the little "escape" plug in the back of the tank.
And after about 10min when it stopped, the tank was on half.
It must be air in the system right ?
