To prevent Nissan Patrol overheating in UAE desert driving, conducting a daily inspection before hitting sand tracks is crucial. Start by checking coolant level and color — clean coolant indicates a healthy system, while rusty or discolored fluid could suggest corrosion or past overheating. Inspect radiator fins for sand blockages and gently remove debris with compressed air or water. Confirm hoses and clamps are secure, and look for wet spots that signal leaks. Check the water pump belt for wear and proper tension; a slipping belt can reduce coolant flow and lead to rapid overheating. Also test your Patrol’s thermostat and temperature sensor to ensure accurate readings. Performing these simple checks before each trip helps detect issues early, improving reliability and reducing breakdown risk in extreme UAE desert conditions.
