i got my gauges working today and i'm reading 160 f coming back from oil cooler. after 20 min. ride. now... does this oil then go to the pump? i've ordered a thermostat but till it comes in should i be concerned? if the oil comes back to the pan to then be pumped i'm not too worried cause it'll warm some ; but that's the 60000 dollar question. does the oil that goes to the heat exchanger go to the top end or to the pan? i'm hoping pan . any thoughts?
