I have a 2001 acr and have been having trouble troubleshooting my coolant problems. First thought was air in the system, but now not sure. I have tried to burp the upper rad hose, change the cap. What is happening is when i turn on the car with the heater on, it will blow hot air for 4-5 minutes and then the temp will spike and it will blow cold air. any thought? stuck thermostat?
