What is this for??
« on: January 09, 2023, 21:49:07 »
What is this for? 1970 280 SL. I thought it was for the dash temp gauge.

Thanks

Does look like it has to be a coolant temperature sensor.

That is the 100C sensor for the later model cars with the emission reduction systems.

Here is the link with the detailed information, plus additional links with photos of the components of the system:
