hi i have as wat the title say. everytime i run my car although the temp guage does not go past the middle line, but everytime i shut off the engine and check the hood i can feel that the temp of the engine is much hotter than most car i checked.and it took a long time for it too cool down. i replace the radiator and the thermostat 5 months ago.. any idea to help me out would be so awsome.. thanx
