Thanks, I have thought about this, but the fact my temps dropped by over 10 degrees after installing the cooler tells me it might be working or no?

I was thinking 5w40 would be thick enough for this set up, isn’t w50 a little much?

Does the oil cooler need to be bled or anything like a standard thermostat to remove air trapped against the plate? Seems like that is what is failing. Is there a way to check for oil circulating through the oil cooler? Maybe feel for a hot feed line.
I don’t know if they need to be bled out, but see my reply above regarding the cooler.


Also it’s important to note, if I drive on the freeway and floor it I can get the temp under 100. It just seems to be mostly at idle and city traffic it goes straight to 105-110c.
