I am so tired of this hummer I have a 2007 hummer h3 was first getting really hot so I put new thermostats, aluminum 4 rows radiator with Efan conversion, new water pump , new belt and pully, drained the coolant system and flushed it and filled it up with dexcool recommended coolant . Still runs hot 🤦🏻‍♂️🤦🏻‍♂️ and when I took it for a test drive, my ac now not blowing super cold air like it used to like wtf , what causes this now ? I am about to trade it and get another car . I am so fed up

 

fan clutch or E-fan? which ever you are using.

 

I have an efan

 

it might not be pulling the air flow it did when new. after sitting in the elements maybe its lost some power.

 

It is brand new it came with the 4 row aluminum radiator and suppose to be pushing 2250CFM

 

My '07 does NOT overheat with OEM clutch fan! Did you check temp with the OEM clutch fan?

 

I have an EFan I don’t have the clutch fan

 

Post a picture or share a link/model number to what you have.

 

4 Row Aluminum Radiator Compatible with 2006-2010 Hummer H3 H3T 2009-2012 Chevy Colorado 2006-2012 GMC Canyon 5.3L V8 with Shroud Fan and Relay Kit https://a.co/d/4Fu2Cy7

bought this big guy but I think the fan may be not strong enough to pull thro it like someone said here ? Cus it’s 4 row and it’s huge and even tho the Efan is 2250cfm still may not be enough for it and the condenser ? If rhat the case I’ll return it and back a 1 row

 

Looks like the fan I have on my pc.
