Lexus RX400h Radiator replacement

Lexus quoted $1100 for a replacement.

I replaced it in a few hours with the following for about $130 (radiator, cap, coolant)

• Radiator:  Denso 2213144..  $80 from RockAuto  https://www.rockauto.com/en/moreinfo.php?pk=4722843&cc=1441484&jsn=365
• Radiator Cap:  CARQUEST Radiator Cap Part No 10241... $8 at Advance Auto
• Coolant:  Just over 2 gallons of ZEREX Asian Vehicle Red Ready-to-Use Antifreeze Coolant.. $13 each from Advance Auto

The swap was pretty straightforward but the bottom 2 bolts were a PITA.

Here's the order of the items that were removed.

Cover under front bumper

Cover over radiator support

Removal of cooling fans

These can be reached by going under the car and facing the fans

far left bolt

far right

Top rail removal

The bottom 2 bolts were a PITA.. The images below aren't mine but they show where they are hidden and they can be removed by going under the car and using a 12mm box wrench.

I placed the screws into styrofoams cups and grouped them by sections as I removed them.
This made it easy to ensure I didn't miss any and putting everything back was simply putting everything back in reverse order.

Added coolant and took it for a test drive to heat up the engine.

The temps are good and no leaks.

old vs new radiator.

Some posts mention the top left coolant intake was reversed but there seems to have been a design change.

This was pretty much an exact replacement.

I did have to remove the foam from the old one and hot glue them to the new one.
