Is there supposed to be something plugged into this or is it a sensor or??? It looks like a 1/2" hose connection or something. My truck is 08 Sierra SLE.

Hold down clips for the firewall liner. They are all over the firewall

- Replacing 2.7L on 2021 Silverado with 2023 2.7L
  
  By jmajor422 · Posted 12 minutes ago
  
  My 2021 Silverado 2.7L (K as 8th letter in VIN) needs a new engine. Just picked up a 2.7L engine from an auto salvage... Salvage yard is telling me this is the right engine. Ran the VIN of new engine and found that it is a 2023 Silverado 2.7L and not a 2021 Silverado 2.7L Is there a proven checklist of things I need to do to do the engine swap OR Should I just return it back to the auto salvage. Looking for some real world advise besides AI... as I don't want to install an engine that will always give me a check engine light. Thanks, JM

  What oil, how frequent it's changed and who does it a personal choice. I will change my oil myself with the products I like until I no longer can do it. No one touches my vehicles, toys or other motors unless it can't be avoided.
