Hello! Overheating is something that needs to be looked at sooner rather than later, to avoid engine damage. The first thing to check when the vehicle is cold is the coolant level. If the level is good and visible in the reservoir, there are probably no leaks present. If the reservoir is empty, then there may be a leak. The cooling system should be pressure tested to see if any leaks can be found. If there are no leaks, the engine should be monitored while it’s running to find the cause of the overheating; this could be a thermostat issue, a failing engine cooling fan, or a blown head gasket. Some of this testing is performed with the engine running, which means hot engine components, so I would suggest hiring a certified mobile mechanic to visit you, and run a thorough inspection to properly diagnose your overheating issue.
