Hi Chuck,
yes the core is installed with the mountings facing upwards. Just like the instructions showed. No question is stupid, got to ask to know
En extra quart was required to fill the oil cooler and lines in total. The mechanic told me that almost one litre of extra oil is in the system now compared to stock. I don't really understand what you mean, but as I have understood it, the oil dip stick now show a full pan, and the extra quart has been distributed in the system.
Now, as I said, we have been going through the installation and we are really puzzled by this. Mainly because it's just a cooler and some hoses, there is nothing really different that should affect the oil pressure. The only thing I can think of is that there is an air pocket somewhere after it's been sitting for a while. But what to do about it?
