Welcome

Some aftermarket fan clutches aren't as good as OEM for some vehicles. You could have a tube or several tubes in the radiator that are blocked or partially blocked also. Are all your shrouds still in place? These ensure the air is being pulled through the radiator and just recirculating underhood air. Have you got anything that would block airflow on the front end. Extra light bars, winch, bull bar, brush guards? Mine idles in the heat too and I can't get it to overheat. AC performance doesn't suffer at idle either

Cool. You're square in the sights of anti-gunners with that scary looking weapon.

Welcome

Their are hosting sites besides F'book.

You have to host the file somewhere else then link to it.

It will have one. Replace the intermediate shaft with the steel guide version that is available. What year did they begin using the nylon? A long time ago, first time I ran across it was in the 70's.

iirc, that's not a wet intake I'd look into this: http://ww2.justanswer.com/uploads/Bluegorilla/2008-12-05_142924_Coolant_loss_5.3.pdf But, to answer your question, I'd replace the knock sensors at this time, if they've not been replaced before. Replace the wiring harness too

Welcome. Posts some pics when you get her done.

Amsoil.com has pretty detailed page

Put synthetic in both. Same viscosity in both also. To follow the fill guidelines you reference, you can use an appropriate size allen wrench using the 90 degree bent portion. Just measure till you find one that is in the range or mark one. Also can use an arts and crafts pipe cleaner since it can be bent. I think you'll end up needing 5 qts between both, iirc. Amsoil.com has a good reference page for your truck capacities
