I have seen posts but still need help. My temp gauge seems to work, but only under the first line before the N in normal. the needle moves to the line and that seems to be where it would normally be at r or m in any other car. fan kicks on as soon as it hits the line it seems. How do you replace the temp sender? where is it at? can i replace it myself? it is just connected to the engine and has nothing to do with the coolant right? it wont leak anything out? i dont know much but maybe i can replace it if i know where its at.
