Ive got a mate whos just bought a rangy 3.9 efi on a c plate. hes said the temp gauge is reading 3/4 after about 2 miles. now i know these v8's run a bit warm but what is the normal operating temp range for this. its not useing any water. could it be a air lock some where in the system or thermostat.
