Haven't had a chance to install the part as yet. Arrived in New condition in a sealed package !
Working great so far! It's been a few weeks and it's working great
Perfect
A good quality part and is working flawlessly, however the time it took just for them to get it in the mail was ridiculous in my opinion. They need to work on that turn over time. It was packaged well
This will only fit the V6 4.3L engine for the Silverado models. Please check out listing: SWA41738 for the correct part you need.
