I was a mechanic for 5 years but all we worked on were imports. When a car or truck would come in with those conditions we would normally check the radiator to see if it was stopped up. If it is you will have to take it to a radiator shop and have it cored and vated. This will clean out the cores that the water travels in and let the radiator do it's job. Right now it is running normal when you are going down the road (lots of air flow) and running hot when you are sitting in traffic (no air flow). The price will differ from area to area-the town that I live in it would cost you about 45-65 bucks. If you go closer to Atlanta (35 miles) it will cost you over 100 bucks.
