I have noticed my sorento's heater doesn't heat up unless the motor is revved. Now the coolant is running out and it is overheating
why did my coolant run out of my sorento? on 2005 Kia Sorento
Take it to a repair shop and have it checked out before more engine damage is done! No way we can tell where your coolant is leaking from.
The advise you were given is correct. Cars need to be serviced by qualified personnel like those at Toyo Automotive in Conyers, GA 770-785-9381. Give us a call before it's too late and further damage happens.
