Overheating in a weird way (to me)

I would bet that something is clogged in the cooling system. First off, take a good look at the front of the A/C condenser (in front of the radiator) and see if it is clogged up with dirt. If it is, take a water hose and spray it until it is clean.

If that does not do it, put a new thermostat in it. A thermostat that is stuck half open could cause this. It is a cheap thing to try if you do it yourself (maybe $15.00).

If that does not do it, then you should try flushing the cooling system. Here is a guide that we have on that: https://www.2carpros.com/articles/coolant-flush-and-refill-all-cars -> note that your car has a radiator cap that is actually on the radiator, not just on the reservoir as in the guide.

Try these things and let us know how it goes.
