car just overheated out of blue no leaks etc. Also heat went cold replaced thermostate. Did not solve car over heats just driving 2 minutes from home and heat blows cold heat was fine before car over heated where to go next. Thought about water pump but wouldn't that leak if faulty. Don't know much past with repairs purchased car four months ago.

Open up the radiator cap, fill it-do not replace cap-start the vehicle get it up to normal temperature-do you see the coolant moving around? If not the water pump has failed. If its moving around have the tests done below

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: Thermostat, Pressure test the Rad. Cap, Clogged radiator, Fan clutch, Radiator electrical fan, collaspe hoses, water pump
