My 07 rx400 radiator has a crack in the plastic. I've researched the forums here and parts sites. I narrowed down to Densa and Spectra. Spectra claims beefier parts and offers two year warranty for $10 more. If you have chosen one of these for your repair in the past please give me feedback and recommendation. Tips on R & R appreciated.

 

I used the Denso who made the OEM one. There are some small differences in the design but the quality is equal to the OEM. Check your electric fans prior to ordering parts. My motors were close to going bad. The brushes were gone and had worn deep groves in the motor shaft. Spin them by hand and listen for clicking. The fans come out before the radiator so I wish I had done them at the same time.

Here is your tip. There is a hidden bolt behind a small round cover behind the grille.

 

I just did this on my 07' RX400h.... Denso was the exact replacement. Got mine off of Amazon ($93 right now).

Lower bolts are the hard ones. Take your time and be patient.


I removed the lower radiator flange (bolted on), to make it easier to install new one. Just be sure to take your time getting it bolted back on once the radiator is in place. My first run, it leaked because I didn't get it seated correctly. Drained coolant, reset, filled, and all good!


Be sure to get the Toyota coolant for your vehicle. 1 gallon is just barely enough...but I went into my second gallon. Get 2 to start with and can return if not used.
