Question about Hyundai Elantra

1 Answer

My 2002 Hyundai Elantra gets hot when sitting in traffic. So far I have checked all the fuses and they are good, the coolant level is normal, and both fans are plugged in. Even when the car is getting hot (about 3/4 on temp gage) only the passenger side fan is running. I pulled the passenger side fan and plugged the driver side fan into the passenger side plug and the fan worked. I have had the car get hot sitting in traffic with the A/C off and ambient temperature in the 50's. I was wondering if both fans are supposed to start and stop together and if so what else I should look at before I start trying to trace out wires to see if there is a short or a cut wire. Thanks, Dave

Both fans don't necessarily have to start and stop together but you do need both of them to adequately cool the engine. If you plugged the harness from the drivers side fan into the passenger side fan and it worked then I think you've ruled out any electrical problems with the wiring. It's probably 1 of 2 things. Either the fan has gone out, or the temperature sensor has gone bad. I would start with the temperature sensor first. They are inexpensive and easy to replace. The sensor just threads into the radiator, usually at the bottom.

Good Luck!

2006 elantra no blowing hot air when sitting at idle temp thermostat reads normal


check coolant level is not to low could also have air lock in cooling system if all seems ok check coolant pump

HOT AND COLD


Sounds like you have an air lock in the heater, needs bleeding. From cold check and top up coolant, run engine without coolant cap put heater control to hot, watch the fluid level, will rise then fall suddenly when the thermostat opens, top up coolant and put the cap back on, later when the engine has cooled down again, check coolant level. Hope this helps.

Motor gets hot


check coolant level, and for leaks, check for cooling fan operation, if those are good and working, possibly blockage in radiator or thermostat problem

What causes hyundai Elantra 2002 tempature gauge fluctuates between normal and hot


The thermostat "seals" the cool coolant giving up (rejecting) heat in the radiator & heater core from the hot coolant absorbing heat in the running engine "block".

When the coolant in the engine reaches a specific temperature (180 ~ 195 degrees) as determined by the value selected by manufacturer or when replaced, it opens and allows the hot coolant in the engine block to be pumped out to the radiatot & heater core for cooling and the cool coolant in the radiator / heater core is pumped into the engine block - replacing the hot coolant. The thermostat senses cool coolant in the engine block and seals shut until the temperature of the coolant in the engine block rises to 180 ~ 195 degrees again. This process continues over and over for as long as needed.

You should check to make sure that the coolant level in the reservoir / radiator is sufficient by checking when cold. Do NOT remove a radiator cap when it is hot! With the cap off, start the engine and add additional coolant as the engine warms up to normal operating temperature. If coolant levels are ok, the trouble could be related to the thermostat or possibly a faulty temperature sending switch. This means that the temperature of the coolant is fine - but the switch or sensor that converts the temperature to a voltage for the gauge on yur dashboard is the problem.

If the temperature is fluctuating up and down, you should have it fixed. Good luck!

2002 ford windstar sel overheating


first check coolant level in radiator coolant level sound low.if coolant overflow jug empty.coolant sysyem low, when add coolant to coolant overflow jug coolant level should stay at full cold mark.if coolant level okay,engine overheat while sitting or moving in slow traffic either coolant fan relay or fuse could be bad.or engine coolant temperature sensor could be bad. coolant sensor turn on cooling fan at certain temperature.hot wire check to make sure cooling fan motor not bad or short in wires.if all is good have pcm check it controls fan relay to through the coolant temperature sensor signal when coolant get hot.

My engine temp gauge goes way up when the car is stuck in traffic, when I begin to roll the temperature gauge goes back down. I assume that this is a sensor issue, can this be changed easily?


I would assume that the sensor is probably doing EXACTLY what it is designed to do....measure engine temperature! An engine will get hot when sitting in traffic if the radiator cooling fans are not working. The engine temperature will then go back down when the vehicle starts moving and air begins to flow through the radiator.
Get your radiator cooling fans checked!

Heater quit working 2001 Hyundai Elantra. Checked


If the heater is blowing cold air, it could be your thermostat. They cost $20-50 at an auto parts store. Also, after the car has been ran for awhile does it come up and stay at normal operating temperature? Is your coolant level normal? If the car is high in mileage and the cooling system has never beeen flushed, it may just need flushed.

Overheating


Should just be the two bolts holding the metal cover on. Follow the top radiator hose if you aren't sure where it is.

Before you do this, make sure you check your coolant level to make sure it isn't just low.

Hope this helps.

Overheating, don't know why


The most common problem with overheating is the thermostat. It becomes plugged and won't allow enough coolant to pass through the system. Another cause could be old coolant. Flushing the coolant periodically (when the coolant appears to have rust in it or has faded in color) is a good idea to keep the antifreeze/coolant up to peak levels. Bost are worth looking into but I'd be surprised (barring any leaks in the sytem) if the thermostat wasn't the culprit here. Best of luck.
