Factory 3B Motor Lower Thermostat Housing Genuine Toyota FJ40 FJ45 HJ45 HJ47 BJ40 BJ42should suit all 40 series with the 3B diesel landcruisers. This housing is particular to 3B engines only.  This item is BRAND NEW OLD STOCK (NOS) from toyota Japan.  They are NOT cheap ass Taiwanese copies.  You won't find better.  This bolts to the head and the thermostat sits in it. I also have the upper cover listed separately.

As expected these items are as good as you will get as they are brand new and will come in toyota packaging and have only been opened for purposes of taking photos. 

If you have any questions please don't hesitate to ask.
