    I noticed my MG1 and MG2 get to about 200 degrees Fahrenheit after delivering food for two hours in 100-110 degree Arizona weather. It seems like the acceleration is not as good as when it’s cooler. Wondering if maybe the water pump is going out and not able to keep up?

    I’m using hybrid app to monitor temps.
