Want to install an Engine Block Heater yourself? This guide may help.

I know this is an old posting. I have 2008 Prius and for years, I’ve been wanting to put a heater in and now that I got one I can’t seem to figure out which hole it should go into. What I got for heater was 11813 part number from Etrailers in the USA. There are 3 holes all have caps this heater is smaller than those three holes as I can’t see any other.

Well I can’t get it in seems the thick end of heater is hitting ribs of what ever it’s under there this didn’t come with grease I had thermal paste in a syringe and that wasn’t working so I put wheel bearing grease on it and still I can’t get it in. I think it’s not lined up properly but it again

 

It is see image this isn’t going to work






I just had an idea I sent the image to a friend of mine and I’m looking at the image and I’m thinking why can’t I notch the backend where the plug goes in grind it off so that it can straighten
