Hey, I’m new to the group but i already have a question. So i have a 2006 Pontiac Grand Prix GXP 5.3 and it’s been running hot constantly (hot coolant display) for about a week after about 8 mins of driving.Coolant is good. Fans kick on. No obvious leaks from water pump or radiator. Replaced thermostat and coolant temperature sensor but still runs hot. Any advice on what cold be the cause of the issue.
