so uh, whats the deal here lol...i see a plugged hole on the pass side head, but it doesnt look big enough for the fan temp switch...
ontop of that its a flippin SQUARE type inlet, not a hex....ive tried everything to get this sucker out, it wont budge.....liquid wrench, vice grips, seriously, you name it, ive tried it....

so does this even support a fan switch thats compatible with my ecm?? or should i say to hell with it and rig it to run constantly. which is prolly what im gonna do anyways...was just curious what the deal was with this plugged port and if i could put a fan temp switch there or just live without the switch.. oh well, any replys appreciated, cept negative ones.

 

Right between the #6 and 8 cylinder spark plugs.

 

yeah, i know where it is, its plugged ...and well rusted in, and ontop of that itsa square type inlet, not a hes..ive used half a can of liquid wrench and type of clamp and vise grip imaginable....the plug doesnt even look big enough for the fan switch to go in the hole.....
