Under normal conditions (no heavy load, no extreme outside air temps)
my scan gauge shows coolant temp to normally be ~204*. Towing a jet ski (~1300# ttl weight incl trlr) up a steep grade (6%) in ~90* outside air temps scan gauge will usually show coolant temp rising to ~210* to 215* occasionally.
Last wknd towing the ski up a steep (6%) grade with ~110* outside air temp my coolant temp rose to 225*. The temp went down as expected after the hill climb. No coolant was lost as the tank level had not changed upon arriving back home. Radiator, thermostat and h2o pump are one year old, and have never given any indication of issues.
My question is this (Tjkj feel free to chime in here). Is a 225* coolant temp under the above conditions abnormal? I realize the cooling system is pressurized and the boiling point of a say 50-50 coolant mix under that pressure is prolly up around 250*.
