Yeah after I made my last post about the cooling fan frame I realized that the broken piece was on the radiator and not part of the cooling fan frame. So I replaced the radiator.
So to recap, I have replaced the radiator cap, radiator, thermostat, upper and lower radiator hoses, coolant resevoir and engine coolant temp sensor. After installing the new radiator, i did a complete coolant flush. Getting to the engine block plug on the driver side was the biggest pain in my ***. My neighbors probably think im a psycho with the amount of curse words I was aggresively yelling at my car haha. Engine temp was 205-215 when fully warmed up. That lasted 8 days. Then yesterday on my way to get my son from school, I heard a squealing sound and I knew right away it was coolant spraying on the serpentine belt. Looked down at my gauges and saw the engine temp gauge climbing up. So the water pump is up next for replacement lol.
I can do it myself but I just said screw it and I am taking the water pump I bought and my car to Lexus dealership and having them install it. That way they can diagnose anything else that is going on.

Well I hope after all that work done your car runs well for 1/2 million miles.

This is what the dealership quoted me. Seems pretty steep no?
Using the water pump I supplied them, it's going to be $1895 to install the water pump, the four bypass hoses and clamps for the pump and coolant. That seems absurd.....

So the dealership replaced the water pump for me 2 weeks ago. Car ran fine the first week or so. Then engine started overheating again up to like 240-250 but then would go back to normal 15 seconds later. I also kept getting P0305 & P0303 misfire codes. Replaced plugs and swapped around coils but P0305 & P0303 were still misfiring. The last 2 or 3 days, I would get white smoke from the exhaust for 15-20 seconds whenever I started the car for the 1st time each day. It would only happen after that 1st start. Then today the car wont start. It tries to but next fully starts. So I had the car towed to the dealership again. The radiator hoses were pretty hard even after the car had cooled down a bit. When I opened the radiator cap, after the engine was cool enough, there was still a lot of pressure in the system and released all the air. Then when I would squeeze the radiator hoses with the cap off, this white smoke came out of the radiator where the cap would be. It wasnt a lot of smoke just a quick little puff. Could have been steam or whatever i dont know ha.
I have a feeling it's going to be a blown head gasket.

Yeah that was in the beginning of this disaster when I was getting P0117. After I replaced that it never went higher than like 260-265

Dealership left me a voicemail a little bit ago saying the technician "found some head gasket damage and wants to talk about pricing out a used motor" 166k miles on the car. Never had any major issues until recently....

I have looked on ebay but I always have trust issues when getting something this large. Do you know of any other engine that would fit into my car that wasnt the stock engine? Something with a little more power that is compatible with my car. That 210 HP sucks lol.
EDIT: Screw it I am just getting a new car.
