Why won't my car level over 2000rpm
A Nissan March 2004 model shows overheating sign on the dashboard every time it overheats.
Is this a good question?

Hello there,
Without more information all I can really do is guess.
A car can overheat for a few different reasons but the main reasons I have seen are the thermostat is stuck/seized or the coolant needs to be replaced because it is dirty for some reason.
This can lead into other causes of why the coolant is dirty but those are two things it could potentially be.

To add to Lee's possibilities, the coolant level could just be low.
In any event, at higher speeds more cooling is required as the engine is working much harder than it would be at a lower speed, and it sounds like your cooling system can't keep up for some reason.
I ran into a similar situation with my wife's Mazda where it would overheat on highway driving; in that case it turned out the radiator was partially blocked and couldn't provide the full amount of cooling needed. Replacing the radiator turned out to be the fix in that case.

Hi @justinjere,
Have you checked out why it might be overheating i.e. coolant level OK, if not coolant leaks yes/no, oil level OK if not oil leaks yes/no or smoky exhaust, radiator fan working OK yes/no?
What have you checked?
