I just replaced my coolant temp sensors and had issues finding the second one, which is the 1/4 turn one pictured in this thread. The main one is a brass threaded unit as described by ym0bc1 in the post above.

The other one is on the passenger side about halfway down the side. You have to remove the main engine cover and another small cover to see it from the top. DON'T go this route!

Instead, take off the passenger wheel and inside fender liner to get to it directly.

Once accessed, pop the connector, then use a small screwdriver to push the locking tab out of the way before rotating it to unlock. You might need a screwdriver to pop it out, the o-ring seals really well. I put a little silicone lube on the new o-ring. If you are quick about it, you only lose a few ounces of coolant.
