I assume the engine temp should read a little higher than the coolant exit temp if the radiator is cooling a little.

One odd thing. Other day I drove it a few mins up to temp and all was fine but the next AM the coolant hoses had sucked in on themselves. Some said it’s a bad rad cap. Replaced it with a different but same spec cap.

That mean anything?

Yeah - I think it means there's air in there somewhere...

You don't mention bleeding the air using the bleed valves? I'm not familiar with the M54 - I have an M57 - but bleeding the air is a MUST do task when refilling the coolant....
