Why does the Aoling CTS overheat when climbing slopes?

[VanMary]

Aoling CTS overheats when climbing slopes due to insufficient engine coolant. Hazards of insufficient engine coolant: When climbing slopes, the engine power increases, generating more heat. If there are issues with heat dissipation at this time, the engine is highly prone to boiling over, which can damage the engine. Adding coolant can prevent such situations. Introduction to coolant: Engine coolant, also known as engine antifreeze, primarily ensures the normal and efficient operation of the engine. The coolant circulates within the engine's fuel tank, providing antifreeze, anti-rust, and anti-corrosion effects.

I've been driving trucks for over 20 years, and overheating issues with the Aoling CTS during uphill climbs are quite common, mostly due to cooling system problems. When climbing, the engine is under heavy load, so the temperature rises quickly. If there's insufficient coolant or a leak, and the heat dissipation can't keep up, overheating occurs immediately. If the radiator is clogged with a thick layer of dust, heat can't dissipate, especially noticeable in summer. If the water pump fails, coolant circulation stops, and a loose fan belt also affects cooling. Once, my truck was climbing a mountain when the temperature gauge suddenly spiked. I stopped and found the fan belt had cracked—replacing it on the spot saved the day. I recommend regularly checking coolant levels, changing it every 5,000 kilometers, and cleaning the radiator to avoid bigger engine damage and costly repairs. For safe driving, if overheating occurs, slow down, stop, and check—don't push it.

As a car enthusiast who has worked on many vehicles, the Ouling CTS may experience overheating during uphill climbs due to several common factors. When climbing, the engine is under heavier load, increasing stress on the cooling system. For example, insufficient or dirty coolant can hinder circulation; a clogged radiator with excessive dust buildup blocks heat dissipation; a loose or aged fan belt prevents the fan from spinning; or a thermostat stuck in the closed position fails to open the circulation channel. I’ve tried inspecting it myself, starting with the basics: popping the hood to check fluid levels, feeling the radiator exterior for cleanliness, and testing the fan belt’s elasticity. Preventive measures include cleaning cooling components during every maintenance session and using antifreeze to extend lifespan. If overheating occurs, pull over immediately to let the car cool down—don’t take risks. These small habits can prevent roadside breakdowns and keep your beloved car running longer.

The temperature of the Aoling CTS soars when climbing hills, which is really worrying. The main reasons are problems with the cooling system, such as insufficient coolant, a blocked radiator, or a faulty water pump. When the engine is under heavy load, insufficient heat dissipation leads to rapid temperature rise, which is highly harmful. I recommend stopping immediately to check the fluid level, regularly maintaining and replacing the coolant, and cleaning the radiator surface. Once the temperature is high, do not continue driving; wait for it to cool down before sending it for repair to avoid engine damage.
