When the engine overheats when AC is not in use but overheating stops when AC is turned ON, there is likely a problem with the cooling fan system. Either one out of two fans is not working or the only fan is not working optimally.
As brake pads wear down, the level of brake oil in the reservoir wear down. Some wrongly react to this by topping the brake fluid to compensate for the level drop. Brake oil should be topped during pads change.
Used tires which are alternative to new ones should be bought with caution to ensure safety. They are to be properly inspected to certify them safe for use before purchase.
Electric radiator fans have different parts some of which are prone to failure. Some of the failed parts can be fixed while some parts should not be repaired.
The battery that enables starting of a car dies after some period of use but faults from other areas can shorten its lifespan. Examples are faulty alternator and bad battery terminals.
The cooling system is a key system of automobiles that controls the temperature of the engine and transmission. Modifying it can cause undesirable consequences on fuel economy, longevity, safety and so on of vehicle parts.
Hybrid cars are known to greatly improve mileage for city driving. They also improve mileage for highway driving too due to some advanced technologies that are incorporated.
Some modern transmissions do not require oil maintenance because they are filled with lifetime fluid that supposedly last the lifetime of the transmission.
The eCVT in hybrid cars have electric motor/generator sets in it which the engine and regenerative brake system uses to charge the hybrid battery. A wrong transmission fluid in it will cause short circuit, malfunction and damage.
