Recently went from raw water cooling to fresh water cooling, but the heating issue was there before the change. Not sure about the oil pressure bc in the 2.5 years of ownership, I never paid attention to it until now (ignorance is bliss).
Overheating:
Goes from less than 100 to over 180 in 15min (at idle). I’ve acid washed and dismantled and visually inspected the whole cooling system twice and see no blockages. I did remove the thermostat before each flush. Original gauges, newer senders. I have a new in box Faria gauge that I will test with the sender. I will also adjust the valve to the thermostat a quarter turn and see what happens and then a full half turn to see what happens. And I’ll report back. I also ordered a Groco 3/4” thru hull and coated it with Barnicle Barrier by Petit that I will be installing in place of the original 1/2” thru hull which I assume is calcified. Note: The fresh water cooling system does have a steel wool filter prior to the return to the hx.
Oil pressure:
Never have I ever adjusted the oil pressure valve so I’ll be doing that and reporting back.
Any other ideas, comments, suggestions are invited and appreciated
Here are pics of initial start up and 15 thereafter
