Symptoms:<br />- at idle/low rpm, temp guage goes to max, pressure guage shows low water pressure<br />- at high rpm, temperature lowers to high end of safe operating range (according to guage) and pressure guage reaads about half of the other identical engine<br /><br />I've just done the folllowing maintenance:<br />- put new thermostats and new water pummp in recently on both motors(which was done to fix this problem)<br /><br />Could it be something else problem causing this? What's the best/easiest way to diagnose this situation?<br /><br />BTW: Anyone know where I can inexpensively get an owners manaul for these engines? What I'm really looking for is a good troubleshooting guide.
