Questions & Answers

Do these seem to be AC Delco?

It's an authentic ACDelco product if you buy it from OverstockDirect.

The 2005 GMC Yukon 5 is compatible with this part. Is it possible to buy a 3 L non-flex fuel car?

It would, as far as I know. The Tahoe 5 I own was made in 2005 by Chevrolet. This is a 3 letter word

Their effectiveness is proven
5/5

A tip that I didn't do was to make sure you have a wire brush on hand to remove any rust from the holes before you install the Metals they touch serve as grounding mechanisms. The knock sensor code for the #2 sensor is one I didn't know, so I'm throwing it again. Make sure you order a new wiring harness as well. The plugs crumble under extreme heat, as the metal is exposed to extreme temperatures. are a few dollars, and the headache they prevent is well worth it. Be sure to use RTV gasket maker around them when replacing them to avoid leakage in the future. According to GM, that's a good idea.

Yes, I agree The original knock sensors from AC DELCO are 213-393-002 The knock sensors are all OEM and arrive with the new blue GM In order to help end users recognize its OEM, we have developed new branding and packaging
5/5

We package all units in bubble wrap and place them in plastic sleeves. A genuine OEM part is easy to identify, rather than old parts that sit on a shelf for years. It will cost more, but you will be glad to have the best parts available for replacement, so you do not have to do it twice. Many types of knowledge descriptions are available on the Internet as well. There is a YouTube video discussing how to replace knock sensors twice as the after-effects There was a failure in the market pair. There are no fault codes left in the system after installation. I bought a 213 from AC DELCO and it was a great purchase A pair of knock sensors for the 2003 Chevy 6 is part number 3521. This may be because I have 177k miles on my car.

A 2006 Silverado with five knock sensors must have
5/5

I tried to buy the cheapest knock sensor I could find for my 2006 Silverado with five. In the end, I put down the money for the original AC Delco parts since a couple of the sets that I received didn't function. The software has been installed and is working properly. Instead of wasting your time with the cheap ones, I highly recommend getting these for your Chevy LS.

This is madness
3/5

There is a problem with the knock sensor. Having removed the intake manifold previously, I have to rip it.

The original and the work
5/5

As a replacement for recently replaced lower cost options, I used these in a 2005 Silverado. We are genuine AC Delco parts and these were the ones that solved the problem.

Replacement of the original equipment manufacturer
5/5

It is a perfect replacement for the OEM. As soon as the new ones were installed, the engine light went off.
