first, make certain the thermostat is not installed backwards, if still hot then remove a radiator hose and see if coolant is discharged with pressure behind it(this checks the water pump); it is also a good idea to flush the cooling system; make sure there is not debris in front of the radiator; beyond all this you may just have to have a professional diagnose it
radiator fan, head gasket,
it is a hyndai that's why it is a hyndai that's why
try a radiator cap......or you have a head gasket leak.
Place a pan under the drain valve on the radiator (back side of the radiator, right side) Reach up and open the valve letting the coolant out. (It is meant to be turned by hand, but you might need a pliers) After the coolant has started draining open the radiator cap to allow air into the radiator. Go back to the engine and open the thermostat cap (Large cap that looks like a radiator cap, has a two step turn - push and turn again removal). Remove the thermostat located under the cap by grabbing it, turning it to break the seal and pulling it up. To fill - close the drain valve on the radiator. Leave the radiator cap off and start filling by pouring the coolant into the (still open) thermostat cap. Note - the thermostat needs to be still removed. Have an assistant watch at the radiator and when it gets full he needs to quickly put the radiator cap back on. Then continue to fill at the thermostat cap till the engine is full. Now start the car and let the coolant circulate, refilling at the thermostat cap when the coolant has dropped. After the car has warmed up, and all of the coolant bubbles have come out, fill the coolant to the top of the thermostat cap housing, replace the thermostat and cap and fill the reserve tank to the warm mark.
Blown head gasket? Air trapped in the system (hasn't bled out yet)? Wrong cap?
The thermostat is located under the radiator cap. Take the cap off and there will be a little metal thing. Pull it out and there it is. The thermostat is located under the radiator cap. Pull the cap off and there will be a metal thing. Pull that out and there it is.
== try changing the thermostat. Make sure system is not air bound Replace radiator cap Make sure hoses are not collapsing under pressure
Clogged radiator, bad water pump, defective fan or fan thermal relay.
I would start off with replacing the radiator cap if it don't have one then the cap on the refill tank ,this may fix your problem .
Maybe it's not the radiator. Maybe it is one of the radiator hoses that is leaking. Or possibly the radiator cap or a level sensor.
thermostat is located under radiator cap!
Well ive had the same priblem. We have got new radiator and cap. Then replaced thermostat then water pump. No more problems.
