So I need help!!!!!
My Lexus is overheating.
First the radiator blew. Replaced it and the engine was still over heating. Next the thermostat was replaced. The Lexus still was overheating. The next thing I replaced was the cooling fan to radiator and my vehicle is still overheating. The water level is reducing but I can’t figure out what else to replace????

 

Sounds like a blown head gasket. If you are loosing coolant and have no external leaks, it's going somewhere right? Into the combustion chambers is the logical conclusion.

 

99.5% this^^^ but has anyone tried to diagnose it? Radiators just don't "blow." You replaced the fans, but are they working? Checked the coolant flow? Tested the radiator cap? Pressure tested the system? Checked the oil for signs of engine coolant?

That said, I wouldn't put any money down on anything other than blown head gasket.

 

If you didn’t bleed the air out of the system after you replaced the radiator there will be air pockets. When the air starts to escape it will seem like you are losing water. Also because there is air in the system the fans won’t turn on and the car will overheat. Not a guarantee that’s your problem but if you didn’t bleed it, that’s most likely your issue
