Hi there. If you did not properly bleed the cooling system after completing these repairs, it’s more than likely that you have air bubbles inside the coolant system causing this problem. However, it could also be due to a bad electrical harness or connection to the thermostat or temp sensor on top of the radiator as well. It’s probably a good idea to have a professional mobile mechanic come to your location and complete a car is running hotter than normal inspection, so they can pinpoint the source of this issue and recommend the right repairs.
