Good evening,
i think i may have stumbled on an issue that hasn't fully presented itself yet... I have a 2003 320 DA with 6.2 Closed cooled blocks... Yesterday I was at the boat prepping for an upcoming trip. (Barnegate NJ to OCMD back to cape may then AC ) I was flipping through my smartcraft gauges via my Garmin while running and noticed my port engine showed that the coolant (fresh water) pressure was at 15 psi while the starboard was at 30 psi. The temps for each engine were fine. They were both identical and where they always are. Cant recall exact # i think 175... anyway i did notice a little coolant under the engine and i believe I traced it up to a hose that may be the cause. I am going to try to repair this before leaving but my question is can low coolant levels cause this loss of pressure? could it just be a sensor? do fresh water pumps go bad? hoping to get down there tomorrow top off the coolant and see if that changes anything.
any pointers would be appreciated. Thank you!
