Hey Scott,

Thank you for the very detailed points - it is really helpful! I agree about the 14 gauge. I went to get some and was surprised by its thickness (and its a bit thick for home shop working. I have so far reverse flushed the engine and radiator, checked the thermostat (actually installed one - there was none in there), and gotten as far as a cardboard shroud prototype.

The truck still overheats in a short short 1 mile stop and go (city) distance (with 60 degree weather), so I am starting to thing airflow, timing, and fuel issues may all be at play.

In your opinion, is the low fan position and the subsequent partial only shroud condition an alarming cause for concern or do you think it might me workable? (it definitely reduces the percentage of radiator area covered by the fan.)
