Keeping a French car's battery alive through a Dubai summer
Cooling system plastics and the thermostat housing are the heat items on the 1.2 and 1.6 turbo engines. For the battery specifically: park in shade where you can, drive far enough to actually recharge rather than only starting the car, and have it load-tested before summer rather than after. A battery that reads 12.4 volts at rest can still fail its load test, and the load test is the one that predicts the morning it does not start.
