I still ( after 5 years ) am not sure if I have a cooling problem with my 300D. Temperatures climb to 98degC when climbing a 200m hill that is 3 km is length ( average inclination 15:1 ) Normal temperature is some 82 deg. Fast ( 120km/h ) driving also results in higher temperatures ( 95 deg ). Ambient temperature 25degC. Is this "normal " or should I change radiator - ( I have changed pump, thermostat, fan-coupler )
They do climb a bit, fairly quickly when load is applied. But if it worries you try a $5 acid flush first. If it makes a difference then maybe it was the radiator. OTOH, if it makes a difference maybe you don't have a problem anymore. It eliminated the overheating problem our SDL had. (Which got a lot hotter than yours did.)
