Review on 🔌 Dorman 917-033 Ignition Knock Sensor Connector for Select Models - Enhanced Performance & Durability in Sleek Black Design by Dan Phillips

If you are working on the knock sensor then a new suspension is a must. That's the very reason you're doing the work in the first place. The old one shrinks from heat, allowing water into the knock sensor cavity. This in turn will corrode and damage the knock sensor. The plugs of the old ones also tend to break off when they are removed, as they become brittle over time. This pendant was well packaged in a box that the pendant was packaged in. The new boots had a nice fit as they replaced the old ones. All plugs can be connected without problems. When starting my 5.3 Silverado, the wiring harness worked as expected and didn't cause any problems. This is an exact copy of the original so you shouldn't have any trouble installing it. I decided to completely seal the new boots with RTV, even though the service bulletin instructed me to only seal the front of the cover. Some things to watch out for when doing knock sensor work on a GM: Make sure you have a day off to do this work, it will take more than 6-8 hours. As indicated below, now is the time to replace the extra parts as the distributor will be disabled. You can also carry out additional maintenance work, e.g. B. cleaning the IAC, MAF and throttle body. Parts you will need: 2 knock sensors (usually only the rear end is damaged, but as this is a lot of work you can swap them out) 1 knock sensor harness (the old one will be useless. The cover will not be airtight and the connectors will be fragile and likely to break) 1 intake manifold gasket (this goes without saying. all together) 1 throttle body to intake manifold gasket (you will likely remove the throttle body for easier removal and cleaning) 1 RTV pipe (preferably high temp. This is used to mount a to create a dam and prevent water from entering the knock sensor) and corrosion) Other Optional: 1 bottle of throttle body cleaner (while the entire manifold is off, you can spend this time cleaning the throttle body thoroughly. 1 bottle of MAF cleaner ( for cleaning the mass flow sensor air and idle control valve). ) Some We Workshop Cloths: (She will clean many parts covered in grease/dirt/grime) Vac Shop: (No matter how careful you are, there is a chance leaves or dirt could get into the valve/knock sensor cavities if you remove the manifold. A shop vacuum will pick up all of this debris quickly.) Other parts to consider replacing while you have your manifold removed: Rocker cover gaskets with gaskets (this is the ideal time to replace rocker cover gaskets if you notice small oil leaks) Heater hose quick disconnects: (These fittings are also notorious for being stowed near the firewall on many GM trucks. If you've never replaced them, now is a good time to replace them as you have easy access to them.) Note: I am not including part numbers as they vary by vehicle.
