Curious if anyone has a coolant flow diagram and/or factory description of coolant flow for the TD6. Also curious what the 2 engine coolant temperatures are. #1 seems to be consistent with Normal operational temperatures of an engine ambient to ~190F. The #2 temp is normally significantly less than the #1, unless under towing or higher ambient temperatures. See GAP screenshot. Ambient temp at time of picture is 46F with the Discovery idling.

 

Thoughts anyone? 😊

 

Tomorrow I'll try and find diagrams.

What are the code numbers?

PXXXXX?

 

I don't have any fault codes. Just curious what the second coolant temp and circuit does

 

I don't think this is all, if you need more I'll try again.

 

Thank you
