Heater blowing cold and gauge showing hot
I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
This is most likely due to a failed water pump. It is also possible it could be a leak/low coolant level, but very likely to be the water pump. You should replace the thermostat at the same time as the water pump
You should not drive the car in this condition.
Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
