GM Direct Injector Testing, Cleaning, and Resealing Service

Restore your GM engine’s smooth idle, power, and fuel efficiency with our Direct Injector Testing, Cleaning, and Resealing Service. Ship your injectors to LaCorte Automotive, and we’ll clean, test, and reseal them to factory or better-than-factory flow specifications using precision GDI flowbench calibration.

What’s Included:

Comprehensive Testing
Each injector is electronically and hydraulically tested for spray pattern, flow rate, and leak integrity under real-world GDI operating pressures.

Advanced Ultrasonic Cleaning
We use professional ultrasonic cleaning and backflushing to remove carbon buildup, varnish, and internal deposits that commonly affect GDI injectors.

High-Quality Resealing
Every injector is resealed with new premium Teflon combustion seals, o-rings, and microfilters to ensure proper sealing and long-term reliability.

Detailed Spec Sheet
You’ll receive a before-and-after test report showing each injector’s flow rate, spray pattern, and balance for complete transparency.
