So I have read most of the valley plate threads and recently completed the work. Replaced the gasket, water pump, knock sensor wiring harness, etc. When researching the project, I saw a recommendation to replace the heat exchanger as these are prone to cracking. I thought I saw a crack forming around one of the bolt holes, so I went to Toyota, ordered a heat exchanger for a 2011 Land Cruiser and finished the work.
Take it for a test drive and realize it is dumping coolant once it's up to temp. Remove the intake to find a hose that was left disconnected. The hose should have been connected to the top of the heat condenser (valley plate). Turns out the OEM replacement part does not have this male hose assembly which is why I missed it in the first place. Part number I ordered was 16877-38020.
Question for someone that has access to a more detailed schematic than I do. Is there a difference in the LX570 heat exchanger and the LC200 heat exchanger? I assume this line is a heat return hose that needs to dump back into the valley plate. Any thoughts before I start over? Is there a different part number that I should have ordered?
