    I have a 2003 Hyundai Elantra and it overheat after driving about 1 mile. I took it in to the shop and they said it was a blown head gasket. Could this be the problem? It runs well just overheats, thought it might be the thermostat?

    I replaced the radiator (it had a hole in it), thermostat and there are no visiable signs of anything leaking and it is still overheating

    I solved this issue by going to a parts store and getting a thermostat and a seal and some RTA sealent.. The location of the thermostat is under all the plastic coverings on the right side of the engine .. Remove those and the air box and air hoses .. If you follow the top coolant hose there is a metal fitting that is kind of oval with 2 bolts on opposite sides on the apexes of the fitting. The coolent hose goes into that .... Now under that fitting is the thermostat ..... B4 you remove the fitting, drain the coolent from the engine to a level that is below the fitting ( about 2 gallons). Note the orentatation of the themostat b4 you take it out and clean the the surfaces and then put everything back in the reverse order and fill the coolent back up. Now remember to check the coolent level the next day due to air working its way out of the system and, voila' your done.

If the upper radiator hose is cool, but the engine is overheated than this could be a sign that the thermostat is stuck. By the way, the thermostat is at the end of the upper hose in the metal housing. There are two bolts holding it to the engine.

Thank you for your help! I took my car in for a second opinion and the mechanic said it was the thermostat! It is now running great and only cost me what the first mechanic said it would just to look under the hood for the head gasket! I saved so much money! Thanks again! :)

My car is overheating and nothing else

Posted on Jan 17, 2009

Well I thought it might be the thermostat and it was. After I replaced it in my driveway with some simple tools, and an inexpensive part, along with a gasket, the problem was immediatly solved.

I own a 2003 Hyundai Elantra LX and currently have just over 63,000 miles. Is this the time that I should replace my timing belt? If so, would it make more sense to have my water pump done at the same...


Yes, you are just about spot on for the timing belt. Leave the water pump - if it ain't broke don't fix it. Changing the belts does not disturb the water pump so wait until it actually starts to leak, and that could be in years to come.

2001 Elantra Temp Fluctuates


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.
