2004 AWD Nissan Murano SE
Ok, so I have a 2004 nissan murano I bought used. When I bought it, it overheated only when driving on the freeway. Went through the entire system with the car lot I bought it from. New water pump, new radiator, new thermostat x3, we even put a refurbished engine with lower miles into it, flushed the coolant system several times until it finally was discovered there was a hole in one of the tubes causing air in the coolant system. Has been driving great for months after that but still no heater, it blows air, just cold air. recently it has started to overheat only when i’m in drive thru’s. the moment I start driving again the temp gauge goes back down but it has started overheating everytime i’m stopped for longer than 5 minutes. any ideas what this could be?
