Hi All. Replaced rad cap after 'loosing' water thro expansion tank pipe to road. Replaced thermostat water is only 'loosing' cup/mug full into expansion tank and NOT out to road.MY QUESTIONI need explaning is...when the rad cap is removed should I see coolant below the kneck?...Does the coolant system suck water back out of the expansion tank to replenish itself?...Do I fill the radiator through the rad cap or the expansion tank. I have no leaks, the Kia Mechanic has used a devise to check not fuel in the water. Heaters blow hot and cold as normal thro front and back heaters.Water temp guage upto half never over.
So how does the rad/expansion tank system work.
Thanks Steve Gx Blackpool
