2004 Chevrolet Impala Fuel Injector Parts Questions & Experts Answers

• Q: How to clean fuel injectors on 2004 Chevrolet Impala?

  A: The required tools for Fuel Injector cleaning include the fuel line shut-off adapters (J 37287) and Fuel Injector cleaner (J 38500-A) as well as the 3/8 fuel line shut-off adapter (J 42873-1) and 5/16 fuel line shut-off adapter (J 42873-2) and 3/8 fuel line shut-off adapter (J 42964-1) and 5/16 fuel line shut-off adapter (J 42964-2). The gm top-engine cleaner is suitable for use and direct fuel tank application must be avoided because other cleaners contain damaging methanol compounds. The cleaning solution should never exceed 10 percent concentration while the total used amount stays at 960 ml (32.4 oz) for this procedure. Us dealers need to pour two 24 ml (0.812 oz) gm top-engine cleaner (GM P/N 12346535) into the cleaning tank but canadian dealers must use 48 ml (1.62 oz) top-engine cleaner (Canadian P/N 992872). A cleaning mixture consisting of 96 ml (3.24 oz) top-engine cleaner and 864 ml (29.16 oz) unleaded gasoline should be prepared when using different brands from the specified solution. Use gasoline to fill the injector cleaning tank while disabling the Fuel Pump before disconnecting the fuel lines which should include proper shut-off adapters as part of the procedure. The cleaning tank connects to the Fuel Rail before pressurization gives power to run the engine until stalling occurs. Reconnect all fuel lines after removing the cleaning tank then run the vehicle engine for two more minutes. Check the injector balance with pressure measurements from each unit then swap out the injector which presents the lowest reading when the difference surpasses 15 kpa (2 psi). Complete the fuel tank treatment with port Fuel Injector cleaner gm p/n 12345104 or canadian p/n 10953467 at one ounce per gallon and instruct the customer to finish the dose at their next fill-up along with recommending brand fuel changes and cleaner utilization every 5000 km (3,000 mi) to avoid further problems. Drive the vehicle to check if the customer problem has been effectively dealt with.
