How to replace the 2.0L motor - 2001 Hyundai Elantra

When water heats fast the temperature must be checked independently to eliminate possible electrical problems with the gauge or sender.

If the coolant really is getting too hot too fast a restricted coolant circulation should be suspected. Thermostat is the most likely cause of low or zero coolant circulation but other sorts of blockage are possible and it has been known for the water pump impeller to fall off the shaft or to break up., though these things are rare. I don't advocate suspecting this unless there really is no flow and this is best checked by disconnecting a heater hose.

A restricted air flow through the radiator or the cooling fan not working would probably cause overheating but that tends to take longer and be unremarkable in the speed of overheating.

It is possible for a leaking cylinder head gasket to pressurise the cooling system and displace coolant and disrupt the thermostat operation.

Clear the code and drive the vehicle. If the code comes back, then you know it's real condition and not a one time event.
Changing the temperature sensor isn't going to remedy the situation. Most likely the thermostat will need to be replaced.

It can be faulty blower motor relay or its issue with blower motor resistor.

Get the blower motor re-inspected. If its faulty it has to be replaced.

Timing marks for a 2002 Volvo S40 2,0L engine:

The lower hose of the engine block just behind the alternator is where you will find the thermostat.

If it's USA made, then it will have an OBD-II computer and standard connector. Try removing the ashtray and look for a rectangular connector, about 2cm by 6cm. If it's not behind the ashtray, it will under the dash on the driver's side, and marked OBD or OBD-II
