"Halfway" does not necessarily mean "Overheat". It is hot outside and machines must work harder!
You still need to monitor it, make sure it does not go higher
I want you to get a Second Opinion with someone "Hands On"
Some take stuff to big shops---others try to go less expensive
I prefer "Less Expensive", "Knowledgeable", and "Able to Complete the Task Correctly"
OR a FREE OPINION!
So here's my recommendation. You can back out if you do not feel good about it!
Play the game!
Go to a popular auto parts store
Have your battery checked/ charging system. This is normal activity at a parts store!
Also separates your target man, from the other employees. And you can converse without the hussle and bussle inside the store
Any embarrassment is avoided
While he is checking, ask about your Temp Gauge, ask if he thinks the thermostat could be the problem. Or can he consult with someone there, who might know.
Also ask if there is an employee there, Skilled, and capable, that could perform the task in their off time.
Sometimes fellers working their do things like this "on the side"
This is not a hard task! Wing it from here on out, as far as price, and location.
I got much of my "Reading and Manipulating" people skills in the 1st Ranger Battalion.
