In some overheating cases I have come across in the last 15 years in the industry there is usually many issues that are coming into play. here allow me to explain.
See, while driving on the freeway the have the wind force in threw the front of the Radiator that will allow the water temp to appear as though the vehicle is running normally. However is a fails reading. In most cases such as this there is usually a crack some where in the radiator its self. Most then likely with that Ranger, beings that it has a foraged plastic upper and lower takes you will find the crack in the seem. It will be extremely hard to see or undetectable to the eye with have a pressure test preform er on the system. You might have also bought the wrong cap as well and be loosing pressure cause the cap is not maintaining the correct pressure needed to maintain the system.
As for the overheating during stop and go traffic. You, without a doubt in my mind have a bad Fan clutch! there is usually a fan clutch the is attached to the to the water pump on the Ford trucks. They have a terrible habit of going out OFTEN! Check it out! If you need to trouble shoot it any further you can contact me via email.
Best of Luck to you. Just Remember, IT IS A FORD!)
