still overheating

[quiky]

Car was overheating. Originally thought it may have been the thermostat or water pump..replaced thermostat and replaced water pump...took it for a drive..still overheats..cant work out what the deal is...going to give the radiator and block a good flush but if this doesnt work could any1 shed some light on what it could be...could it possibly be a cracked head?

It could be a cracked head, coolant leak, sliping fan clutch, a bad cooling fan, a collapsed lower radiator hose, or a dragging brakes. The problem with the supra I bought, The reason it was overheating was Alot of Exhaust back pressure, because the converter was clogged.
