Overheating with thermostate out.no leaks hoses good

sounds like your blend door is either stuck open or stuck close

First check the coolant level and top up if needed. If it is within maximum and minimum level then check Thermostat valve which should open on reaching high temperature and thereafter it maintains optimum temperature needed for highest efficiency of the engine or timing should be checked which is other reason for overheating of engines.

If it overheated i would replace the thermostant and gasket, also make sure its full of coolant, after replacing the thermostat you may have air in system so let it run until stat opens it may boil over a little until stat opens then it will **** coolant into block when that happens fill with coolant, you will need to let it idle for a while before new stat opens, hope this helps, good luck, i think the stat went bad the first time it overheated.

The first thing is to make sure there are no coolant leaks,and next run the engine and feel both top and bottom hoses as it starts to run hot, if both hoses are not about the same (meaning hot) then you have a bad thermostant, if both hoses are hot then you may have a problem with the colling fan, most of the time its a bad thermostant or theres a leak in the system.

It could be a faulty thermostate or a bad water pump. Water pump is on the passneger side where the fan belts are. Good luck

It sounds like your water pump may have gone bad. The water pump pushes the antifreeze through the engine, heater core and Radiator which is regulated by the thermostate. Sorry for the bad news but i hope this helps, and Good luck

try to flush the system wit presure water stright and reverse but make sure before flushing u must took the thrmostate out from housing and thermostate must be in right possion .

This is caused by you coolant temp sensor you will need to also get a thermostate tp go along with it. This sensor goes bad on elantras all the time giving you a false reading and then finally your car will overheat causing major damage. spend the money to get it fixed now cause i see your out of warranty. joe hyundai tech ps check your top radator hose see if its leaking near the back clamp if it is you will see a white crust. get that fixed to if you see that. you will need a hose and clamp.

change the thermostate and gasket after you change it let the truck heat up then cool then refill the radiator again after the thermostate opens do not open the radiaator with the truck hot or the upper hose hard

1. start the engine and leave the radiator cap open.
2. put a cardboard cover or a rug in the front of you radiator.
3. let it runs 20 minutes or more, see if it is overheated and see the water or coolant in the radiator circulated or not. If not, as soon as you have already changed water pump. thermostate and check the hoses, no leak, I think your radiator was blocked.

Did you put stop leak before?
