**Minnesota weather**
My H3 Alpha Cammed runs cool in the winter with the temp gauge needle slightly under halfway line my Scanguage II reads 180-190*F at that point doesn't matter with the heat on or stop and go traffic or idling it'll never go past the halfway line.
Runs hot in the summer with temp gauge needle at halfway line but creeps up to 3/4 line on stop and go traffic or idling my Scanguage II reads 200-240*F at that point and even to the RED-LINE but with the AC on my Scangauge II reads 250*F at that point ENG HOT and AC OFF light comes on cluster. Without AC on It still reads high 200*F on hot days.
Here's the thing I did and replace 5,000 miles ago..
-New ACDelco Coolant 50/50 mix
-New temperature sensor/sender
-New water pump
-New 2 row all aluminum radiator
-New 187*F thermostat
-Took out the oem factory clutch fan and did a electric fan conversion onto the radiator behind it
E-Fan Specs
-Single 12inch 10 blades Puller electric fan is rated at 2150CFM 12volt 80wattage 12.70amps
Is my e-fan to weak? For sure it pulls less air in than the clutch fan I think that might be the cause
People that has a E-fan on their Hummer which one did you go with??
I prefer the E-fan over the clutch fan why because----> less noise, little more mpg, little more hp/tq
If nothing can solve the problem im guessing the clutch fan is going back on
