With just 50,000 miles on it, my 14-year-old T40-C (MBE 900 330 HP) is presenting with overheating issues. I power washed the radiator to make sure it wasn't packed with dirt. No improvement. I replaced both thermostats but the condition persisted so I replaced the radiator. Yup, still throwing codes (220 degrees) on even the most gentle of hills and even just highway grades.
I'd hate to think after all this it might be the simplest (and cheapest) of options... the sending unit/sensor or the dash gauge.
Has anyone else experienced this and if so what (if anything) caused/corrected it?
Thanks in advance (I hope).
