Coolant in the head will get hot much faster than the rest which is where the sender is. I've had cars and trucks go way to the right and then fall quickly as the stat opened. One thing I always do is drill a very small hole in the stat to act as a bypass . Doesn't affect the temp but gets the air out of the system .
