I had the turbo rebuilt on my Yanmar 4lha Stp and I just finished reinstalling it this morning. Everything seemed to be fine, turbo spooled up as it should, boat reached its normal speeds, but the temperature climbed to just under 180 under load. Normally it runs at a bit under 170 at load. Idle temp is 160 as it has always been. When I took the load off the engine, it quickly returned to 160.
Some coolant was lost when reinstalling the lines to the turbo, but the amount was under 12 ounces, oil pressure seems to be good, the temp just seemed high. The water temperature on the river is about 80.
Any thoughts? Clean the heat exchanger? New coolant? Impeller?
There also is not a bleed valve at the turbo to remove air introduced to the system, is this normal? Will the air in the cooling system purge itself?
Thanks for any and all help.
