The install looks great. Your wiring is clean as well. Nicely done sir. 👍🏻

 

Hello just wondering how your Efan upgrade is holding up thinking of doing that same thing my truck runs hot in the summers with the a/c on 238 degrees was the hottest it got. I changed every thing you could think of still didn’t make a difference this is my last resort.

 

So far I am happy. It has been cold here in Pittsburgh so I don't have any feedback on a hot summer day with A/C (yet). I will post an update this spring and summer.

So far the truck warms up much quicker in the winter and it doesn't sound like a school bus (my clutch fan made a lot of noise, even after changing to a new AC Delco replacement). The temperature holds steady without issue, and I think I may have gained a nominal mileage increase.

@1371rank Not sure if this will help your problem or not. I would recommend giving it a shot. Make sure that the shroud fits snug against the radiator and use a rubber gasket. Let me know if you have any questions.

Ok thanks this is driving me nuts it only Gets hot in the summer if it’s above 96 degrees and with the A/C is on. My scan gauge 2 reads 238 degrees. Someone on this forum or the Colorado fans forum told me it’s ok to be at that temperature but doesn't seem right to me especially if it’s just idling to reach those temps

 

238 is high, but remember the system is under pressure so boiling point is higher. I have seen 225 once or twice (Scan Gauge). Have you flushed your radiator or considered a new radiator? I know some with I5 have replaced radiator with the V8 version. Since yours is an '11, should just fit right in and has greater volume.

 

yeah I’ve changed the radiator, Water pump, pulley idler, thermostat,radiator cap, temp sensor and fan clutch. Last summer when it was a hot week anytime it got to 96 degrees it started it would hit 238 degrees while idling. so the V8 radiator is a straight drop in and the shroud hoses that I currently have will work to or do I have to do any mods. Thanks for responding.

 

I did not do the conversion as my truck had the V-8 radiator (to go with the V-8 engine) when it was delivered in 2010. But hopefully somebody that has done it can answer your questions.
