224 is fine..... most cars with efans, kick on around 227-228....
food for thought, bigger radiator means more water to keep cool... Not saying the 34 in radiator is a bad investment, bc of more surface area.

FWIW, I have a 34" radiator now with OEM truck fans and a stock thermostat. I have a 40k trans cooler and a Maggie heat exchanger in front of the radiator. I towed our boat up a large hill in boost for about 2 mile straight with the A/C on and the ambient temp over 100* and the highest I ever saw my ECT was 214.

You have a stock thermostat? I had a 160 and a 180 and during the summer my truck would try to overheat on me all the time (with 34" radiator, and with both factory e-fans and a factory clutch fan). As soon as I went back to stock it's all fixed. I think the coolant was not spending enough time in the radiator to cool down properly.

It was around 95 degrees here a couple weeks ago and setting idling in the drive thru I watched my temps when I was logging go up to about 230-240 and I had never had my truck do that ever, had it since it was new.
New stock thermostat, stock 34" radiator, stock fan clutch. I might try another new thermostat and see what happens maybe even might go with at least a 180. It was strange because I have been through 5 summers with this truck and the 90+ degree temps have never caused it to heat up like that.

Well i got my fan connectors today from DC_Justin for the 05+ efans. I will be ordering a new 34" radiator ($165 shipped) and some new 07+ efans ($212 shipped) in a day or so... Interesting thing while researching this 05-06 efans have 1 fan with 5 blades and the other with 7 blades. The 07+ both have 7 blades... HOpefully i will know next weekend if that solves my problem...
