I spent some time this weekend actually reading up on how to look after my car properly in this climate, instead of just guessing. I found this guide that gives a really clear detailed overview of why our cars take such a beating here, especially the battery. It broke down the science simply, like how the heat makes the battery fluid evaporate and the internal parts corrode much faster. It also explained why parking in the shade isn't just about keeping the steering wheel cool, it genuinely extends the life of your battery. It was one of those reads that makes you realize how many simple mistakes you've been making for years. Highly recommend having a look if you want to understand your car better.
