Had my radiator replaced because it was leaking tranny fluid from the bottom of the radiator. Problem now is the AC doesn't work. My shop hooked the AC machine up to discharge and recharge, and even ran a test for leaks and found nothing. The AC just doesn't come out cold. Anyone know what could be causing this from possibly replacing the radiator?

Its funny how I work at a luxury car dealer and you guys usually find the answer faster than they can.

 

Maybe someone left something unplugged when they reinstalled the radiator. aC clutch relay comes to mind

 

Thats what i was thinking about leaving something unplugged, ill ask tom about the AC clutch relay thanks!

 

Did they reconnect the fans?

 

Air comes out of the vents just not cold.

 

Fans at the radiator, not inside the car.

 

Going to have them look at it tonight, the fans do run at the radiator. I don't hear the loud noise of the compressor for the AC turn on and off like it usually does though. Hasn't turned on yet just quiet with full AC turned on. Still no cold air.

 

Compressor plug got unplugged. Thanks for the help guys

 

Internet detectives for the win..

 

Is the faulty radiator common in 3rd gen TLs? My original radiator failed leaving me stranded on the side of the road (dumped ENTIRE tranny fluid). I had it towed to garage and mechanic installed new radiator (not OEM). About a month ago I noticed tranny fluid leaking on my garage floor. I thought it was residual fluid from the first radiator. However, it didn't stop so I called my mechanic back. Same piece was faulty and he had to install another radiator. I suppose it's complicated seeing as the tranny fluid is also hooked to it.

 

Crappy install, crappy quality radiator.. who knows what it could be. maybe your front radiator support is damaged somehow causing undue stress that keeps breaking radiators. Too many variables to just make a general statement like, "3g radiators are bad" Correlation =/= causation.


Go buy a quality DENSO radiator on amazon and let your mechanic replace it. Make sure he only uses Honda Blue coolant in there

 

There is nothing special or complicated about our radiator setup that I know of...many cars have the transmission cooler integrated into the radiator. Is it common on our cars? I wouldn't call it common...but it does happen. I can recall a handful of posts about it in the past year for sure...but keep in mind, we are talking about a 8-12 year old car at this point...things unfortunately will fail at this age and requirement replacement....no matter the car.
