On a normal startup, the oil cooler would still have oil in it, even after an oil change. In fact, even after an engine change. On a mk2 with the external oil filter assembly, I would suggest it would be wise for an operator to fill the pump housing with oil before closing up the lid. On my personal modern vehicles, I always do this as well when I change a cannister filter with the exception of those engines where the filter points upwards.
I will be starting an engine soon in a carrier that has had all the lines and cooler replaced or blown clean. In that case, I'll be priming the cooler system with a bucket-pump to prevent the minute or two that the engine would otherwise be running with minimal oil pressure.
