We divided into our teams, and got our assigned vehicles. In my Electronic Diesel Engines class, we were assigned to the 09 Cascadia. Sometimes I think my teacher likes to give my team difficult tasks just to see how we react.. In this case, we are taking out the coolant temperature sensor.. That doesn't sound too hard right?... WRONG! While looking at this thing I'm thinking how in the hell are we supposed to get this thing out?!? We had to take a bracket off just to get to the plug.. then the amount of space you have to try and fit a wrench to crack the sensor loose is unbelievably small.. I have to get a wrench and shove my arm under the frame and try to get to the sensor. With a little bit of time, patience and a few busted knuckles I finally got it loose.. That was just the beginning, we then had to get a catch pan to drain the coolant out, and ended up with coolant all over the floor, but that's nothing floor dry cant fix!
