I just had my engine serviced. 2 termostats & waterpump were replaced.Now I have a cooling problem. Anytime I run over 3000 rpms for 5 minutes I get the temp. alarm and the engine automactically reduces the rpms. One thing I don't understand is why the water pressure runs up to 22lbs as I advance the throttle and drops suddenly as I pass thru 3000rpm.The engine has only 380 hrs logged.Need some hints.
