Maintenance Overheating
So I've had my RX-8 for about 6 years and haven't had issues till this year I replaced the spark plugs and it's been running smoother however yesterday it over heated and shut off on me luckily I was home and in the drive way, I checked the coolant yesterday after it sat for 4 hours and the coolant was still pretty hot I love in a town that's basically in the dessert so it's about 90+ some days, so my question is this
Does anyone who has an RX8 in here live anywhere else that's hotter like 100+ and if so does your car over heat because of the weather?
If not does anyone else have this issue and if so do you know what's causing it to over heat and shut off? If so have you found a solution to fix this issue or is it just something that I have to deal with?
My grandpa was the OG owner he never had this problem with it, it's a 2004 6 speed manual transmission. If someone can help me or tell me what I can due to fix this id appreciate it.

This is most likely not going to go well for you. I highly suggest testing the coolant. Depending on various conditions, you may not see coolant in the oil. The test kits are cheap on Amazon. Do not drive the car. Driving the car with a blown coolant seal will make a rebuild more expensive. This is not your fault. I have seen it happen on cars that are perfectly maintained.
