How to Prevent Engine Overheating in UAE Summer: A Master Mechanic Guide

Engine heat is the number one cause of unexpected vehicle breakdowns on UAE highways during summer. Here is how to safeguard your engine against thermal breakdown.
Key Coolant System Checklist:
- Coolant Concentration: Never use pure tap water in modern engines. Always use 50/50 distilled water and OEM anti-freeze/coolant with high boiling points.
- Thermostat Function: Thermostats stick over time, restricting coolant flow to the radiator.
- Expansion Tank Cap: A cracked coolant reservoir cap fails to hold pressure, causing coolant to boil at lower temperatures.
What to Do If Your Temperature Gauge Spikes on SZR:
Pull over safely to the shoulder immediately, turn off the engine, and open the hood. Do NOT attempt to remove the radiator or coolant cap while the engine is hot!
