Default 1991 F150 thermostat replacement

I have a 1991 Ford F150 (XLT Lariat) 4x4, 5.0. I would like to relace the
thermostat. The two bolts that hold the thermostat housing are in a very
difficult place to get a wrench on. Is there some special tool or some trick to
getting at the bolts.

Well you have to hold your head too the right and cuss for about a hour and then and only then will you get the wrench on them. Sorry man those are the brakes.

Yep - they're a real bite in the shorts to get at. A socket universal joint helps with the angles.
