Can coolant seals go out even when the engine is off?
I have a temperature gauge installed on my car and I always monitor the temperature when the car is on. I never let it go past 100 degrees Celsius as I flip the fans on when it reaches around 100C. What I am concerned about tho is when the vehicle is off. When I park the car I keep it running for like 3 min with the fans on. When I turn the vehicle off, is there a chance that the temperature can rise and blow out the seal? From what I understand coolant doesn't circulate when the engine is off, would this be a good or bad thing?

If the coolant is "cool" (under 200F) when you shutoff the car, the seals will never get that hot even when heat soaking. Generally what kills the coolant seals isn't "overheating" as in 240F, its when you overheat your coolant it boils, allowing localized temps to skyrocket in the vapor zones. Once the car turns off you'll heat soak yes, but not enough to cause damage. I have a feeling if heat soak could be eliminated this would extend the life of the coolant seals, but as is you are operating well within the design parameters, heat soak is just something you just have to accept.
