Sam it should be installed in the lowest section of the hose you can.

im sorry oldnavy, but i also still dont know exactly where to put this thing either. it comes with a bunch of hose clamps and a "t" that fits in the hose that goes to the heater core. it says to tee into the lowest part of the bottom hose but it doesnt say which way the flow should go. it has 5/8" nipples on each end and has arrows indicating flow direction but the way i have it installed right now doesnt seem to be working. (i should have mentioned that i am not very experienced with this sort of thing and may need it "dumbed down"). sorry, i just cant quite picture it. and i was also wondering where people were mounting these if they already have them (ie-firewall, wheelwell, etc.). sorry for my ignorance, and thanks for any info!

What's a block heater for?

Winter cometh.

Sorry if I seemed a little gruff, if the way you have it installed doesn't work just mount it the opposite direction. If I remember correctly the bottom hose has the flow toward the radiator and that would be the direction I would think you would point the arrow towards.
