🤦🏻‍♂️ No, the radiator cap regulates the pressure. As coolant gets hot it expands, raising the pressure. If too much pressure builds up the cap opens to decrease pressure and allow coolant to flow into the overflow reservoir.

Your car would also be spraying coolant every time it warms up.

This would be something I’d get the dealership’s opinion on considering this is a known issue. I would question why they’re recommending a long block, and not just a new head. An engine that got hot usually doesn’t mean it’s toast.

I read on another forum that incorrectly torquing those brackets will cause small stress fractures that lead to them snapping under load.

Does your car have the 2.2l diesel?

Start simple and check the condition of your battery terminals, or have your battery tested. If I was the tech diagnosing this that would be where I start.

As long as the airbag light is on, your vehicle is not fixed. If Mazda claims it cannot be fixed, you’ll need to discuss your options with the insurance company that handled the claim.

You’re going to be limited to a high mileage first or second gen Mazda2 or Mazda3. Both reliable cars, but make sure they’ve been well maintained!

Unfortunately, this is just a drawback of buying a new vehicle of the latest model year. When a problem arises, you are often waiting on the solution.

In my experience, they are not worth it. Ride quality isn’t great, and they can be loud. Their manufacturers advise against repairing them if you do pick up a puncture, so most shops will refuse to patch/plug them, which means you’ll be replacing it. Most shops don’t keep them in stock either, so you’ll be more than likely waiting for your replacement if you want to put another run flat back on. Save your money.
