  Q: How to service the fuel injector on Buick Park Avenue?

  A:

  The Fuel Railroad must be taken off before you can extract the Fuel Injector retaining clip and the Fuel Injector. Detach both Fuel Injector upper o-ring and lower o-ring while paying attention to prevent damage to electrical connector pins and nozzles and maintaining the injector out of any cleaner solutions. The installation should begin with proper o-ring replacement while placing the black o-ring on top and the brown o-ring below due to their dissimilar material composition yet equivalent dimension. Vehicle owners should apply engine oil to all fresh o-rings to prepare them for installation. Install the Fuel Injector lower o-ring before adding the upper o-ring and then attach the Fuel Injector to the Fuel Rail through the retaining clip. Finally, reinstall the Fuel Rail. Every service operation must use the correct Fuel Injector assembly part number because cleaning fuel injectors as complete assemblies must prevent the use of all cleaning agents.

  Q: How to clean fuel injectors effectively on Buick Park Avenue?

  A:

  The tools required to clean fuel injectors include the Fuel Line Shut-Off Adapters (J 37287), Fuel Injector Cleaner (J 35800-A), 3/8 Fuel Line Shut-Off Valve (J 42873-1), 5/16 Return Pipe Shut-Off Valve (J 42873-2), 3/8 Fuel Pipe Shut-Off Valve (J 42964-1), and 5/16 Fuel Pipe Shut-Off Valve (J 42964-2). The GM Top-Engine Cleaner requires exclusive usage and should not be added into the fuel tank while the maximum cleaning solution should be limited to 10 percent. When an odometer shows less than 160 km (100 mi) the entire system needs new injector replacements rather than cleaning operations. The required cleaning solution measures 960 ml (32.4 oz) and can be obtained through the usage of two Fuel Injector Cleaner (J 35800-A) tanks. US dealers need to empty two 24 ml (0.812 oz) GM Top-Engine Cleaner containers with GM P/N 12346535 into their cleaning tank while Canadian dealers should use 48 ml (1.62 oz) of Top-Engine Cleaner with Canadian P/N 992872. The mixture of 96 ml (3.24 oz) of Top-Engine Cleaner and 864 ml (29.16 oz) regular unleaded gasoline can be used as a cleaning solution. Run the cleaning process by first filling the injector cleaning tank and then disable the fuel pump before disconnecting both fuel lines and plugging them with proper shut-off valves. The Fuel Injector Cleaner (J 35800-A) needs connection to the fuel rail after setting the pressure at 510 kPa (75 psi) before starting the engine till it stops. After detachment of the cleaning device athletes must reattach fuel lines and drive the car for 2 minutes before performing the injector balance test. Perform the Injector Balance Test to check fuel pressure losses in each injector before replacing any device with pressure decay higher than 15 kPa (2 psi). The fuel tank needs one ounce of Port Fuel Injector Cleaner (GM P/N 12345104 or Canadian P/N 10953467) for every single gallon of gasoline but this should be supplemented with the remaining amount during the next fill-up. The customer must use GM Port Fuel Injector Cleaner at regular intervals of 5,000 km (3,000 mi) for injector cleanliness. Drive the car to prove that the customer reported issue was effectively dealt with.
