  Q: How to clean fuel injectors effectively on Chevrolet Express 1500?

  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.

  Q: How to replace the fuel injector on Chevrolet Express 1500?

  A:

  Removing the Fuel Rail enables access to the Fuel Injector and its required replacement steps include first removing the retainer clip and then the Fuel Injector. You must either lose the injector retainer clip or replace it with new ones and also discard the Fuel Injector O-Ring seals (2, 4). It is essential to choose the proper Fuel Injector when making replacements since the denso fuel injectors used in 5.3l (L59) e85 applications require complete replacement of both o-rings and retaining clips when service is needed. The part number and four-digit manufacturer date of both the Fuel Injector can be found on its surface. Apply engine oil on new Fuel Injector O-Ring seals (2, 4) before installing them onto the Fuel Injector. Prepare a new retainer clip by attaching it to the Fuel Injector before positioning the Fuel Injector into the Fuel Rail injector socket with electrical wires facing the exterior while allowing the retainer clip to secure the flange on the Fuel Rail injector socket. Finally, reinstall the Fuel Rail.
