Review on 🔧 Enhanced Denso 475-0508 Expansion Valve for Improved Performance by Alexander Craner

This was a great price on a Revain and an exact replacement. If you are performing a system flush prior to evacuation, you will need to access the passenger side evaporator, which is located under the dash on a 2000 Toyota Avalon. The evaporator must not be flushed through the expansion valve. If you go to the trouble of accessing the evaporator to flush it out, you might as well get a new expansion valve. You don't want to go back to Dash again. In fact, if the vaporizer was bad and didn't just need flushing, I'd shut everything back up and drive a hot car. Removing the vaporizer would require more fitting removal and I didn't want to do that. Luckily mine was fine and just needed a flush.
