I need to have the dealer install a block heater on my LX. The local dealer here in Cleveland is giving me grief telling me that such a thing does not exist. I travel far north in the winter and I have to have a block heater. Every other Land cruiser and 4Runner I have owned has had one. When I looked online I found a heater with part number PU140-00905, which I believe is a Lexus or Toyota OEM part for that engine. Can anyone like Beno confirm that part number and that it is OEM Toyota or Lexus ? I really appreciate it.
