Does the cooling system needs priming after flushing? Hyundai Tucson 2006 2.0 litters.
You have air in the system that's needs to be bled out
Agree with CamroC,burp it.
Is there a bleeding valve?
No, bleed air by loosening the reservoir cap but DO NOT remove completely, may take several times, keep checking level, check for heat in the car, once you have heat it should be good, usually.
i turn the heat on and keep filling to all the air is out
Thank you guys. In the end it turned to gases from the engine through the head basket.
