half is normal though slightly above half maybe a issue. for more accurate results hook up a obd scanner, youll find that if at half it will be 88-92C and at slightly above half it is 100-102 then its normal as the car can reach in peak hours if its more than this than you can have a problem. just verify your fans are working and you have coolant. I have owned two thai shape facelift accords in the past and this is normal. dont know if its different in a CL9 though.
