Thanks K9sar! Well i got done putting in the thermostat and man did it make a huge difference! The heat was luke warm to cool so i knew what i had to do but didnt realize it was making my pathy run so cold. The temp gauge never got off the cold line even after several hrs of driving this summer to camp site. And it always ran kinda crappy at highway speeds..no power a little chugging. My thermostat was not opening up and therefore engine never getting to proper operating temp. So changed it out and it was covered in rust! The previous owner didn't apparently see the need for changing coolant. Got everything back together and let her run for about 5-7 min. Temp gauge started climbing and the heat was working great...like it would run you out of there! So went for a drive an instantly noticed alot less chugging and more power at 60-75 mph. Great! Funny how something so simple could cause all that! Anyways here are pics of the process just in case someone needs a hand.
took off idler pulley bracket
after removing lower radiator hose removed thermo housing, very tight space!
the old thermo was caked in rust and a black gunk! looks like an OE part w 200K!
all parts cleaned and ready to go back on
clean area good to get gasket material to stay on! And install jiggle valve in Up position
all put back together and ready to fill and bleed system for air
now here's where my temp is running and heat works great!
