Re: 350 Heating Up at Stops

Here is an update and future plans:

-I removed the A/C clips and screwed the shroud up tight. (pics below)
-Just in case, I enriched my idle circuit significantly.
-I have found that my old radiator was a heavy duty which I replaced with a 2 core Champion, which should be plenty for what I use the truck for. (I have ordered the appropriate mounting hardware) (pic below)
-I ordered a Hayden HD fan clutch and a seven blade fan.
-I added a pic of the gage at what I believe is 180 degrees (it will run at this position all day as long as I'm going over 20mph).

With the shroud up tight and rich mixture I am now getting warmer when idling but not hot (like 200 vs 220). I was hoping this was enough to truly "fix" the issue but apparently not.

FYI, once complete, I will have:
new 2 core Champion radiator
new HD water pump
new HD fan clutch
new 7 blade fan
new 180 degree thermostat
new outlet neck
new hoses
new coolant
new radiator mounts and pads

I don't think there is anything else that can be done.....
