My dealer put an inline heater in the lower rad hose. I wasn't happy at first but it works fine.
If you do go for the real core plug type block heater you may find that not all block locations have enough clearance in the cooling passages to accept the heating element.
Maybe someone can chime in on where their's is installed.
I have had the problem of a block heater not fitting when a parts house sold me the wrong one. That is why I was hoping someone could tell me the the lenth and angle of bend needed to fit. I can use the pump type but up here they seem to burn out fast. I will go that route if i do not hear anything eles. Thanks for the ideas.
i found the block heater. My dealer decided to look at other equipment that uses the same size engine and got a part number form there. I will post the part number once I proof it.
