All of the on-line parts diagrams list three different temperature switches on the coolant manifold of the M88/S38 engine. They are the "Temperature time switch, the Temperature sensor and the Temperature sending unit/warning contact, numbers 9, 11 and 13 on the diagram." My problem is that the coolant manifold on my car has mounting points for only two sensors. The question is which two sensors are on the cars with only two sensors? I have checked the ETM for the M6 and can find no listing for the temperature time switch. The ETM lists alternate locations on the S38 engine for all shared switches, but there is no M6 location for the Temperature Time Switch and the location pictures show the two switches as on my coolant manifold. Unfortuneatly, both switches are identified genericaly as a Temperature sender and as a Temperature sensor. No clue as to if one is a Time Switch. I am begining to think that the NA M6 may not have a Temperature Time Switch at all. Boy, am I over my head with this one. HELP.

Found out that the NA M6 does not have a Temperature Time Switch. Cold start is handled by the ECU and Tempurature Sensor. So that explains why only a Temp Sensor and a Temp Sender on the NA version.
