  Q: How to clean fuel injectors effectively on Chevrolet Venture?

  A:

  All cleaning tools required for this task include fuel line shut-off adapters (J 37287), Fuel Injector cleaner (J 38500-A), 3/8 fuel line shut-off adapter (J 42873-1), 5/16 fuel line shut-off adapter (J 42873-2), 3/8 fuel pipe shut-off valve (J 42964-1), and 5/16 fuel pipe shut-off valve (J 42964-2). Use gm top-engine cleaner exclusively and never incorporate it into the fuel tank while the maximum cleaning solution concentration remains at 10 percent. The required cleaning solution volume equals 960 ml (32.4 oz) and can be obtained from two tanks of the j 38500-a product. Us dealers need to empty two 24 ml (0.812 oz) gm top-engine cleaner containers having p/n 12346535 into the j 38500-a while canadian dealers use the 48 ml (1.62 oz) top-engine cleaner with canadian p/n 992872. You need to combine 3.24 oz (96 ml) of top-engine cleaner with 29.16 oz (864 ml) of unleaded gasoline when you use a different cleaning product brand. Initiate the cleaning process by filling the injector cleaning tank with gasoline but first stop vehicle Fuel Pump operation and disconnect fuel lines before using shut-off adapters for plugging the fittings. You should attach the j 38500-a to the Fuel Rail before applying 510 kpa (75 psi) pressure to the system until the engine stalls. The injector cleaning process ends with reconnecting Fuel Pump lines and relay while operating the vehicle for two additional minutes. Obtain the results of the injector balance test by measuring pressure drops from each injector then replace the device with the lowest measurement that shows more than 15 kpa (2 psi) variation. The technician must add one ounce of port Fuel Injector cleaner (GM P/N 12345104 or Canadian P/N 10953467) per tank gallon instructing the customer to finish the measure at the following gas stop. As extended maintenance, the technician should recommend fuel brand switching alongside regular injector cleaner use every 5,000 km (3,000 mi). Drive the vehicle before giving the customer to verify that the original concern has been effectively addressed.
