I have also gotten the water pump changed, there was leak in the pump. But still the temperature gauge is M on highways and between A and L in stop and go traffic. Could it be the cooling fan. How can I test if the cooling fan is running properly ? My mechanic told me that "if the needle does'nt go beyond L to the red area, cooling fan is alright". Is that true ?

thanks,
