How to clean the throttle of Toyota Prado?

1. Unscheduled cleaning will lead to wrong throttle opening.

Second, it will cause air with impurities to enter the engine combustion chamber.

These two results lead to abnormal engine operation, mainly manifested as unstable idle speed; Sudden and instantaneous stall at high speed (the feeling that the throttle suddenly closes); Power drop; In severe cases, it will cause difficulties in starting and increase fuel consumption.

Step 1: Prepare the tools.

10 small wrench (remove the battery terminal), large Phillips screwdriver (remove the air inlet elbow), T30 internal wrench (remove the throttle), and a bottle of carburetor cleaner.

Step 2: Remove the throttle intake elbow of Toyota Prado.

Step 3: Unplug the Toyota Prado accelerator harness plug.

Step 4: Remove the Toyota Prado valve body.

Toyota Prado throttle function: control the air intake, and the oil quantity can be automatically controlled by the throttle position sensor. In other words, it is a device that controls the throttle.

Classification: one is to control the semi-mechanical and semi-electronic throttle through cables, and the other is to calculate the relationship between throttle opening and intake air volume and sensor angle through signals sent by sensors, that is, full electronic throttle.

Toyota Prado oil usually adds a few liters.

Toyota Prado uses 5 liters of oil for 2.7 displacement. Usually add 5 liters of oil. First pull out the dipstick of Toyota Overbearing 2.7 and see the highest and lowest positions. If the oil is below the lowest position of the dipstick, add some oil. When the oil is higher than the highest oil level of Toyota Prado 2.7 oil dipstick, do not add it, and pump out the excess oil. Therefore, the optimal oil level is between the highest oil level (upper limit) and the lowest oil level (lower limit).

It should be noted that when the engine oil of Toyota Prado 2.7 is added, the added engine oil should be as consistent as possible with the engine oil of Toyota Prado 2.7, and different brands and varieties of engine oil should be avoided to avoid the reaction of different additives in the engine oil.

If the engine oil of Toyota Prado 2.7 is added too much, it will increase the amount of engine oil splashed on the inner wall of the cylinder when the crankshaft and connecting rod rotate, which will greatly increase the amount of engine oil entering the combustion chamber of Toyota Prado 2.7, increase the carbon deposition in the combustion chamber, increase the piston motion resistance and reduce the engine power. With the increase of engine oil entering the combustion chamber, the exhaust emission deteriorates, which affects the service life of the three-way catalyst and may damage the Toyota Prado 2.7 three-way catalyst in serious cases.

Naturally aspirated engines require ordinary oil quality. Mineral oil and semi-synthetic oil can be used. If the budget permits, you can use synthetic engine oil. Compared with self-priming engine, turbocharged engine has more precise interior, more complicated working environment, better engine oil performance and better lubricating oil fluidity, so it is best to use synthetic engine oil.

For the choice of engine oil brand, emphasizing the long-term effect of engine oil, Mobil engine oil can be selected. Care about the cleaning ability of engine oil, you can use shell lubricating oil; Castrol recommends using oil with strong oil film toughness. For example, turbocharged engines are prone to carbon deposition when running at high speed, so Shell synthetic engine oil with strong cleaning ability can be used.
