Check the auxiliary cooling fan for operation. As the engine temp rises, it should kick on to bring the temp down. U may have a bad motor on the fan, or more likely a bad fan switch.

Hi! Your cooling system need checking.Engines are designed to work under all conditions so if u r in traffic your gauge should not be like that.

    What? OF COURSE the thing needs to be checked! They're looking for what to check, not "take it to the shop." If it is the auxilary cooling fan, they're very easy to check and replace if needed.

If you have a viscous fan hub then have it replaced as it is not drawing air through the radiator at idle or slow speed (crawling traffic). Check that are no air locks in the system as they will cause heating problems.

It probably low on coolant. The heater will blow cold when there is not enough water (coolant) to keep the heater core full. Check the radiator (not the overflow reservoir) when it's cool.
