i was takin a trip on the highway and if i set the cruise at 80 the car would start to overheat, well the needle would keep rising past half, but if i set it at like 72 mph i had no problem...is my timing advanced too much or is my thermostat junk or somethin else?

 

water pump?

 

also think might be the water pump

Are there any leaks? and where?

 

new water pump and timing belt ...naw no leaks of any kind but i am throwin a code 43 too...that might have somethin to do with it lol
