## Cooling Systems

**Air Conditioning:**  
Heat stresses your A/C compressor. Have it serviced if it's not blowing cold. Refrigerant levels should be checked and topped if needed.

**Engine Coolant:**  
High temps cause overheating. Ensure your coolant is fresh and at the right level. A clogged radiator or weak fan belt invites trouble.

**Hoses & Belts:**  
Heat cracks rubber. Inspect hoses for leaks or soft spots and belts for fraying.

## Tires & Fluids

**Tire Pressure:**  
Warm air expands; tire pressure rises in summer. Check cold (before driving). Overinflated tires wear unevenly and reduce grip.

**Oil:**  
Summer heat thins oil. Switch to a slightly heavier grade if recommended in your manual.

**Transmission & Power Steering Fluid:**  
Both suffer in extreme heat. Have them topped off.

## Battery & Lights

Heat shortens battery life. Have yours tested. Check all lights for function.
