Engine Cooling System over cooling - DTC P218100 - V8 Kovomo
Transaction No.: 2060205/5
Customer statement / workshop findings
Customer statement

Emission Control Lamp illuminated on the Driver Instrument Panel (Figure 1)
•
The time to reach the correct engine coolant operating temperature has increased.
Figure 1
Workshop findings
•
Diagnostic Trouble Code (DTC) ‘P218100 - Cooling System Performance’ is stored in the Engine Control Module (ECM), the vehicle
“warm up” time is longer when compared to other vehicles of the same type.
Technical background
It is possible for the engine coolant Thermostat to corrode over time, this corrosion is due to an adverse reaction of the Thermostat material with
the engine coolant.
The corrosion and subsequent build-up of debris prevents the correct operation of the thermostat when closing, resulting in over cooling. The
ECM triggers a DTC when the target engine temperature is outside of the specified parameter.
IMPORTANT NOTE: The instructions within the Measure section must only be followed if DTC P218100 - Cooling System
Performance’ is stored within the ECM.
Production change
Under investigation.
Measure
1) With a confirmed customer complaint of MIL activation, accompanied with DTC ‘P218100, Cooling System Performance’ proceed to
replace the engine coolant thermostat (Figure 2) - Refer to 19 – Engine cooling – Coolant regulator (Thermostat insert) (V8 biturbo) –
To remove and fit.
TIP: Within the quoted Rep.Gr procedures there are single use items which must be replaced and not reused. Ensure that
