done 108k miles,regularly serviced by myself/reliable mechanic friend -it runs hot in traffic,needle climbs to 120 degree mark(top white mark just below the red mark on the temp gauge),but never boils over,and needle returns to the centre after electro-magnetic fan cuts in. .My car has three sensors on the front left hand side of the cylinder head,my suspicion is that the coolant temperature fan switch opens late,hence it runs hot,can anyone tell me which of these three switches described above is the one i need to replace?
ps--have replaced the coolant at the 108k service and checked that the radiator is not blocked-it is hot all over-no cold spots-therefore the stat must also be ok.
look forward to some replies -by the way this forum is a great place to share ideas/help each other .
