Ive been having my temp gauge go right up to red and come back to 12:00 every now and again.
Ive changed the temp sender in the bottom hose, and the thermostat and bled the system several times..
then ive stumbled on there being another temp sender in the head....number 13 here
its part number 13621433076 and looks like this...
Anyone have any ideas where it is? the real oem pic isnt too clear.
