i have a 2005 jeep grand cherokee limited 4.7 and the temp gauge while driving is at about a line or two below half but when sitting at a light it rises to about half and then goes back to a little below half after driving for a min. any idea what this could be ?
This is normal as long as it doesent go above half. If it goes above half while sitting at a light check if the radiator fan is working. It wouldnt be the thermostat if it drops to cooler when you are moving.
