Engine coolant temperature climbs to 120C, heater blowing cold air. seems as if coolant finally starts to flow across heater core because heater will start blowing hot and engine coolant temp gauge to 100C. Temperature up and down from ~100-120_C. Suspect ACC mono valve. Would like to hear how hard a job to replace on my 1990 300E. |
