I have a 94 Honda Accord and lately (now that it is freakin' hot outside) I have noticed that the temp gauge reads a little hotter than normal. Imagine that the guage has a 10 point scale where 0 is lowest reading (cold) and 10 is the highest (hot). Usually the gauage sits at about "3" once the car reaches operating temperature. Lately when I am driving on the highway I have noticed that the gauge sits at "4" and sometimes it gets a little higher than "5". The car is not low on coolant, the thermostat was replaced in '03, and the coolant was replaced last year. Does anyone have any ideas?
Thanks in advance.
