Below is what you can check.
Park your car overnight and make sure the pavement underneath is dry. In the morning if the pavement is wet with liquid, you could have a water pump leak.
Grab opposite ends of the water pump pulley and check for "play" (looseness): Try to rock it back and forth. There should be no give. If there is, the bearings are going and it's time to replace the water pump. By the time you can feel play in the water pump pulley, you may also be able to hear the bad bearing when the engine is running - there may be a low-pitched grinding noise coming from the water pump pulley.
Visually check the water pump behind the pulley for signs of a coolant leak. If the water pump gasket is leaking, it must be replaced.
Also vehicles can overheat and or not cool properly.
Now at that.I don't see that is your problem. The engine temp is okay. It is the heater which leads me back to air in the system.
Have you found anything since our last chat?
