It is recommended to perform a non-dismantling cleaning of the Prado's three-way catalytic converter every 20,000-30,000 kilometers or once a year. Three-Way Cleaning Agent: It can simultaneously clean the engine's intake system, combustion system, and exhaust system. It effectively, quickly, and efficiently removes gum deposits in the intake tract and combustion chamber, as well as chemical complexes attached to the oxygen sensor and three-way catalytic converter. Purpose of Cleaning: The removed gum deposits and chemical complexes will be fully oxidized and burned into gases for discharge. This achieves the goal of controlling exhaust emissions, significantly reducing CO, HC, and NOx levels. After cleaning, the vehicle will show noticeable improvements in fuel atomization performance, increased combustion efficiency, reduced fuel consumption by 5-20%, enhanced cold-start capability at low temperatures, reduced noise, improved power performance, extended engine and three-way catalytic converter lifespan, and proper vehicle maintenance.

What are the consequences of driving without coolant?

Driving without coolant can leave the car's engine and radiator unprotected. A lack of coolant affects the heat dissipation efficiency of the radiator, preventing it from achieving the necessary cooling effect. Without proper coolant circulation, the engine may overheat, and in severe cases, this can lead to engine damage. In cold climates, it may also cause the engine or radiator to freeze, resulting in engine failure and rendering the vehicle unusable. Methods to check if coolant is low: Observe the coolant warning light on the dashboard. If it lights up, it likely indicates low coolant levels, though it could also be due to excessively high cylinder temperatures. Inspect the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving; add coolant promptly. Check the water level markings on the coolant overflow tank. The normal coolant level should be between the maximum and minimum marks. If the coolant is below the minimum mark, it indicates a deficiency.
