Engineover heating at complete stops - Forenza Suzuki Cars & Trucks

First thing I'd check is if the radiator cooling fan(s) are operating.

The only times the fan is needed is when the engine is at an idle.
When the car is moving, the air stream forces air through the radiator without the fan.

A lot of fans on newer cars are electric, and controlled by a thermostat, which turns on the fan(s) when the engine gets to a certain temperature.

If this is the setup you have, you'll need to warm up the car to operating temperature, then at idle, check under the hood and see/hear if the fan(s) are running.
