لقد تم طلب القطع وتم تركيبها ولكن للأسف لمبة الماكينة مازالت تعمل وعند محاولة فك الحساس كان يدور في مكانه تكلفت كثيرا من اجل هذا .. لا انصح بشرائه

I had a licensed mechanic install these sensors and they did not work. I have a 2002 Silverado 2500 6.0l I keep getting the low voltage on #2 code. Truck only has 180k KM. Not liking Chev engineers right about now, #2 was full of water.

I'd like to preface this with the fact the harness worked (and is still working) like a charm. The knock sensors however are very cheap and poorly made. **On the plus side, the seller did refund me for the cost as I ended up having to take this to a mechanic to drill out one of the broken sensors. The installation seemed overwhelming, but there are some great YouTube videos out there that will walk you through the entire process. The torque on these sensors is really low, only about 15 ft lbs. The issue for me is that even after replacing them, the car threw errors for both. When I tried removing them, the nut portion spun freely from the housing, so only the top was spinning and they weren't backing our. I used a chisel to lightly tap around the top so the nut would catch the rest of the housing. This worked well for the front sensor. When I did this to the rear sensor, the top half of the sensor broke off leaving only the bolt in the engine block. I tried backing it out with some extractors, but that broke. Three days and $750 later, my mechanic removed it and replaced them with OEM sensors (at $122/ea.) TL;DR, buy ACDelco sensors from an auto parts seller and save yourself a few hundred dollars and several hours of four letter words. What a royal pain.

Work as they should for a fraction of GM dealership cost
