Essential Car Checks Drivers Must Know Before Summer Travel

Regular vehicle maintenance remains crucial, particularly before embarking on extended journeys. Although modern cars automate many functions, drivers still need to monitor certain systems. Before setting off on summer travels, a thorough vehicle inspection is essential for safety.

One critical check involves the engine's cooling system. The coolant level should be monitored in the expansion tank, ensuring it stays between the 'min' and 'max' indicators. This check must be performed only when the engine is completely cold and the car is on level ground. If topping up is necessary, it should be done cautiously, never exceeding the 'max' line to allow for expansion when the engine heats up.

Coolant degrades over time, typically lasting three to five years. While its clarity and color can offer a visual clue to its condition, a hydrometer can provide a more accurate assessment. However, replacing the coolant and flushing the system to remove sediment and rust should be handled by professionals. They also perform essential tasks like properly bleeding the cooling system to prevent overheating, a procedure that can be complex in modern vehicles.

Checking the engine oil level is another task drivers can perform themselves, and they can add oil if needed. Nevertheless, oil and filter changes, along with other engine-related inspections, are best left to service professionals. This ensures all critical components are handled correctly, maintaining the vehicle's overall reliability and safety.
