If there is anybody out there with a honda, who put in an EBH, lemme know. I don't know which kind to get or where the best place on the head is to stick it. I really want one I can just plop on the outside of the head without drilling or anything. I am lazy.
I have a 91 civic hatch that I have recently modded for the winter (i.e. wai, grill block, 195f thermostat, m1 0w20) and want that last important mod besides a belly panto really make up for the cold, an engine block heater.
most engine heaters are oil pan heaters, aren't they? either that or a coolent heater, I would think that warm oil would do the most good as it would flow, and warm up the rest of the engine fastest (a gallon of hot oil should be able to hold alot of heat, right?) so it seems like a vaugly universal type heater should work fine, or you can alwas ask the honda dealer what they install.
just asked honda parts, and they say there is an external bolt on that they use on their new cars. The one that I would need on a 91 has been discontinued. He said the new cars have a bolt on the head that is removed and replaced with the external EBH. He did not know whether my 91 would have this bolt hole or where on the block it might be, as he didn't even know where on the block they currently have the bolt. I will look on my block and see if I can find a bolt somewhere.
Metro, I'd love to go that route, but my skills are limited, and don't you have to remove the head and put the heater inside the block? just found this magnetic, but you said these are pretty inefficient, huh? Are they any less eficient than the external bolt on, you think?
edit: Your oem 300w external is a lot sweeter than the oem honda 15w. went on a hch site where these guys are talking about plugging in for 8 hours. no thanks! and they all paid $135 for that. 60 for part, and another 75 for the dealer to screw the thing in, and run a couple zip ties.
just realized the magnetic prolly won't work on hondas, cuz don't we have aluminum blocks? hahaha
