Question about 2001 Hyundai Elantra

4 Answers

Coolant fan turns on when it should not.

I have a Hyundai Elantra 2001. My coolant fan comes on when the outside temperature is around 60-70 degrees and the air conditioning is not on. The temperature gauge reads a little below the half way mark as it has since the day I purchased it. The sensor was replaced with no change. My car is not overheating but it doesn't make sense that the fan is kicking on when it shouldn't be. Any ideas?

The fan is computer controlled. It comes on when the temp is approxamaty 225F. You need a scanner to see what the computer is seeing to start with. Maybe you have a restricted coolant passage somewhere. Sometimes the fan relay sticks and the fan will not turn off until the relay cools off. Without looking at this and testing components its going to be hard to guess for anyone. We would just be throwing parts at this. Computers do become faulty which is why I can't recommend a part. Computers also sometimes need to be reprogrammed.

The outside temperature has nothing to do with the cooling fan. The temperature of your engine tells the fan when to come on and off.I dont think you have a problem.You just needed some information about how your car works.

My cooling fan will not turn off. 2001 Hyundai Elantra GLS 2.0 l engine


1. Check the scan data for engine temperature to see if it shows that the engine is running hot. The ECM will turn the A/C relay off if it thinks that the engine is overheating. Check engine coolant temp sensor

2. Test voltage at the Powertrain Control Module (PCM) pin 50 (Yellow) and pin 58 Yellow/Black. Both should have battery voltage when the system is turned on and the engine is running. If not, then the wiring needs to be checked.

3. If battery voltage is present on the two pins, then manually ground pin 68 (Orange) at the PCM and this should ground the A/C relay and the clutch should engage.

4. If it does, verify that the PCM powers and grounds and connections are good.

Hyundai Elantra temperature goes up to HI when air is turned on


There is an electric fan that should come on with the AC and run whenever the AC is on,if it doesn't come on it will heat up very quickly. Sounds like a problem with that radiator mounted fan.
The fan is supposed to come on when the engine gets hot enough also.
If so, the AC should be ok at hiway speeds.But you need the fan to work.

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!

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.
