2002 Buick LeSabre Parts Questions & Experts Answers

• Q: How to service the fuel injector on 2002 Buick LeSabre?

  A: The service procedure starts by removing the Fuel Rail followed by taking out the Fuel Injector retaining clip together with the Fuel Injector. Precise removal of the Fuel Injector upper o-ring and lower o-ring should be done while maintaining careful attention to avoid damaging electrical connector pins or nozzles. The Fuel Injector must not be submerged in cleaning solutions because its electrical nature poses the risk of destruction. The injector assembly should be ordered precisely since a part number identification gets stamped on it. Engine oil should coat every new o-ring before installation where the mechanics must first put on the Fuel Injector's lower o-ring followed by the upper o-ring. You should connect the Fuel Injector to its designated space on the Fuel Rail followed by the installation of the Fuel Injector retaining clip before reattaching the Fuel Rail. Engineered replacement of Fuel Injector o-rings remains essential for service work because fuel leakage will damage the oil repository.
