High temperature strikes, safe and worry free! Summer Maintenance Guide for Sightseeing Cars

Author：DavisDate：2025-7-5

With the scorching summer heat wave sweeping through, tourist buses in various scenic spots are experiencing a peak in operation. Continuous high temperatures, strong ultraviolet radiation, and variable weather pose severe challenges to vehicle performance and operational safety. To ensure the safety and comfort of tourists' travel and extend the service life of vehicles, a professional team has specially sorted out the key points of maintenance and upkeep for summer sightseeing vehicles, to safeguard your summer operation!

1、 Core Protection of Power: Battery and Charging System

·  Heat resistant charging and discharging: It is strictly prohibited to charge vehicles immediately after exposure to direct sunlight, and the charging environment should be ventilated and cool. High temperature charging can accelerate battery aging and even cause thermal runaway.

·  Water level monitoring: Lead acid batteries need to regularly check the electrolyte level and replenish distilled water to the specified mark in a timely manner to avoid exposure and damage to the electrode plates.

·  Power management: Avoid deep discharge (below 20%), charge in a timely manner at high temperatures, and maintain battery health. Charge as needed, shallow charging and shallow discharging are preferred.

·  Interface cleaning: Keep the charging interface dry and clean to prevent short circuits or poor contact caused by high temperature and humidity

2、 Safety cornerstone: tires and braking system

· Accurate regulation of tire pressure: High temperatures can easily cause tire pressure to rise, and the cold tire pressure needs to be adjusted according to the manufacturer's standards (usually slightly lower than in winter). Be sure to check before driving every day.

· Tread depth and scar inspection: Ensure that the tread depth meets the standard and there are no bulges, cracks, or foreign objects embedded. Tires with severe wear and tear are prone to bursting on high-temperature roads.

· Braking efficiency test: The brake is prone to decay due to overheating at high temperatures. Regularly check the thickness of brake pads, brake fluid level and quality (anti boiling point), listen for any abnormal noise, and maintain sensitive braking response.

3、 Cool Source: Air Conditioning and Cooling System

·Deep maintenance of air conditioning: comprehensively clean the dust and willow catkins on the surface of the condenser (high-pressure air gun or water gun) to ensure heat dissipation efficiency. Replace the air conditioning filter to ensure clean and strong air outlet.

·Confirmation of coolant status: Check the coolant level and freezing/boiling point indicators. Supplement the same type of coolant when insufficient to prevent high-temperature boiling.

·Cleaning guarantee for radiator: Clean the gaps and debris in the radiator of the water tank to maintain optimal heat dissipation performance.

4、 Vehicle body protection and daily maintenance

·Sunscreen care for paint surface: Long term exposure to sunlight accelerates the aging of the paint surface. After regular cleaning, apply specialized vehicle wax to form a UV protective layer. Prioritize choosing shaded parking areas.

·Light wiper inspection: Ensure that all vehicle lights (especially turn signals and brake lights) are functioning properly. Check and replace the aging wiper rubber strip to cope with sudden rainfall in summer.

·Routine oil inspection: Check and replenish key oil such as steering assist oil according to the manual requirements.

·Safety confirmation before driving: Before starting the vehicle daily, check the tires, lights, and dashboard for any abnormalities to ensure that the vehicle is in good condition.

5、 Scientific Operation: Optimization of Driver Habits

·Stable and energy-saving driving: avoid sudden acceleration and braking, reduce battery and braking system load, and lower energy consumption.

·High temperature speed limit driving: Moderately reduce the speed during extreme high temperature periods to reduce the burden on the motor and battery.

·Reasonable itinerary planning: scientific scheduling, avoiding continuous high-intensity operation of vehicles, and reserving heat dissipation time.

Sightseeing buses are not only the service card for the flow of scenic spots, but also an important guarantee for the safety of tourists. Facing the test of scorching heat, only by implementing refined and preventive maintenance can we ensure safe and smooth travel every time. Let's take immediate action, with a rigorous attitude and professional skills, to build a strong safety line and create a safe, cool, and enjoyable summer journey for tourists!
