A/C Compressor locked up on IS250

So here are a few recommendations if you have ~150k miles on this car:
1. Check how much a new Denso condenser costs. They come with a drier already and are probably a lot cheaper than you realize. It will be a cheaper built Chinese version but still worth replacing
2. If you are replacing the condenser might as well replace the radiator with a new Denso unit. Same thing, they are probably a lot cheaper than you realize. It will also be a cheaper built Chinese version.
3. Since you are going to have the radiator and condenser removed, this would make a mighty fine time to replace the water pump as well because it will never be this easy.
4. If you have an Autozone near you, they rent out the vacuum pump and gauge set for free. You just need a kitchen scale to make sure you put in the correct amount of r-134a. I haven't checked so I am just throwing a number out here but assume the is250 takes 1.36lb of r-134a. A can is 1lb so you fill it with one can until empty. You then weigh the can with the valve installed to find the empty weight. Now you subtract that from the next can until you put in the remaining .36lb. Good luck.
As mentioned earlier, I replaced the a/c compressor on a 2002 Camry. I also replaced the condenser and radiator (but not the water pump as I had previously replaced it). The car had somewhere around 250K miles on it at this time. I had a scan gauge hooked up to the car and could monitor coolant temp, inlet temp, etc while driving the vehicle. After replacing the condenser and radiator, I noticed a BIG change in temperatures. Definitely recommend.
