Answers :

Need water pump has plastic torbine and slips off metal gear so change water pump and thermostat
Bad thermostat? Your thermostat is likely not opening, so the water cannot flow through its cooling circuit. Replace it IMMEDIATELY with an OEM thermostat; the aftermarket ones are troublesome.
