I removed the clamp and hose from the engine block on the driver's side of the car per the instructions found in the forum. While pulling the hose off the metal tube the hose fits over also came off. The block that the tube came out of is near the thermostat housing and and has two sensors in this block. So, what is this block with the two sensors and how do I remove it to repair or replace it. I can post a picture later if that will help.
