• Q: How to clean fuel injectors on 2004 Cadillac Seville?

  A: The required equipment for cleaning fuel injectors consists of fuel line shut-off adapters (J 37287), Fuel Injector cleaner (J 38500-A) and three adapters of different sizes (J 42873-1, J 42873-2, J 42964-1 and J 42964-2). The cleaning operation requires gm top-engine cleaner, U.S. P/N 12346535 or canadian P/N 992872. Add solution only to j 38500-a at a maximum concentration of 10 percent. The cleaning procedure for j 38500-a requires two solution tanks to reach the total amount of 960 ml (32.4 oz) cleaning solution. Prepare for the operation by disabling the vehicle Fuel Pump before disconnecting the fuel lines and plugging them with the proper adapters. Connect the j 38500-a to the Fuel Rail before pressurizing it to 510 kpa (75 psi) while running the engine unit it stalls. The vehicle needs to operate for another 2 minutes following the removal of the j 38500-a then returning all fuel lines to their original position. Test all injectors for balance using the proper equipment while replacing the injector that drops its pressure by more than 15 kpa (2 psi). Also add port Fuel Injector cleaner gm P/N 12345104 (Canadian P/N 10953467) at the rate of one ounce per gallon of gasoline to the fuel tank and provide gm port Fuel Injector cleaner maintenance recommendations to the customer.
