So i recently had to replace my radiator due to a leak at the top around the seal. I researched everything before i jumped in but failed to realize that in order to pull the radiator out without removing ac condenser i would have remove the front bumper in order to acess bolts holding them together or either disconnect ac lines and just get system recharged after i put in new radiator ,so i chose the latter which was just so much easier ,so i pulled radiator and ac condenser together took ac condenser and bolted it to my new radiator and put them both back onto the vehicle hooking up all ac lines and hoses exactly how they were from the beginning after doing so i had a close friend who is a profesional licensed ac guy come over and vaccum the system down,fill with nitrogen just to make sure there were'nt any leaks and that everything was properly connected,he then released the nitrogen and recharged the system with 2 pounds of refrigerant...initially ac started to get cold but suddenly started to blow warm... Cant figure out whats going on every time i turn ac on it blows cold for maybe 30-45 seconds but then gets warm...is there a reset button or a fuse i have to replace,im pretty sure everything is hooked up correct and would hate to go to dealer for something that could be a simple fix.. Any advice

 

Any chance he overfilled it? And the thing runs until it realizes the pressures are too high - from an overfill - then it shuts it off as a safety mode. I'd charge it again. I'd also check to make sure every plug and connector are plugged in.

 

When you remove the radiator, there is no need to remove any AC components. You need only disconnect the cooling lines at the rad. No need to remove the bumper either. I replaced my rad in about 90 minutes.

 

^ I'm with him. Didn't have to remove the ac components or the bumper. The two pieces are bolted together. I sent RF a message that night asking how to....and finally saw the two bolts on the bottom.

 

^^ Well, it's done now and its not working. First thing is to check the pressures with a gauge. The guy who did this should have one. Suunds like the compressor is switching off. You should be able to hear that just before it starts blowing warm.

Otherwise, its a trip to the AC specialist shop.

 

hey guys thanks for the help there was 1/2 pound to much freon in the system after letting the extra freon out ac wrks great ,was kinda scared for a second thanks alot you guys!!

 

Glad to hear it all worked out... without any extra work or $$

 

Sweet gotta love good news.

 

 

Here some advice, Spend $150 for a Toyota Denso radiator from Rockauto.

Do a search. it is easy. Lots of 10mm bolts to remove. and 2 sneaky ones at the bottom of the radiator which prohibited me from lifting it out. The radiator is BEHIND the AC condenser which looks like the radiator. Don't loosen any of those lines on the condenser otherwise you'll let the Freon out. I let about 5 seconds worth out. I refilled what I lost. The lower lines connected to the radiator is to cool the transmission. If you drive up on ramps to access the undercarriage the transmission fluid in the line will drain back into the pan. It's best to have ramps for this job

 

Hi friends, sorry, that info was for another thread in the RX330 forum and have no idea how it got here.
