Re: temp sensor location and temporary engine temperature - Saabnet.com Bulletin Board
The temp sensor is located on the side of the engine block, so yes it does provide a pretty accurate temp of the coolant inside the actual block. When you run AC it is constantly cycling on and off, so one short cycle is not a huge deal. You also move a lot of air through the engine compartment which cools of the back part of the engine. You also create a 4l of coolant the engine can thermosyphon while it heat soaks. The fans also cool down the manifold Personally, I think it makes a big difference in peak underhood temps after shutdown, but I have not done any testing to verify this.
