did you fill it to capacity? you need to heat the car up till the t-stat opens and top the radiator off.

Using the heater will always help drop engine temperature.

Have you checked to see if your rad fan is on, [running] when gauge indicates engine temp. is high?

Overheating only when stopped or moving slowly is an indication of a rad fan not working, at speed there is enough air movement that the fan is not needed. 94
