i have a 04 kia sadona i have been having issues with the van overheating someone told me to open the bleeder valve and let it drain then refill leave the valve open and if i see bubbles in the radiator than its a blown head gasket. is this true? is there a bleeder valve on this and if so where is it located? its not on the thermostat housing i allready replaced the thermostat.
Remove the radiator cap when cold and run the engine. Have someone rev the engine while the transmission is in park (with the parking brake ON), and you watch in the top of the radiator for bubbles. It may take a few seconds from the time they rev till the bubbles rise to the top.
Yes it does have a bleeder valve, it should be on the side or in cooling hose, if your coolant has been low and you added you have air in the system, open bleeder valve till flow comes out smooth while engine is running and warm, when good flow is established and radiator is full close valve, should be good to go and will now be full and no more heating up.
it doesnt have a bleeder screw. are ur fans coming on when it satrts to overheat?
