Please only buy a GM Genuine fan assembly. They are more expensive but will last. The aftermarket fans will not last as the resistor pack will fail because the resistors are not as heavy duty as the GM.
I have replaced my daughter's 2014 fan twice...1st time with a Duralast-failed in 5 months. And recently with a GM.
Your 2014 also may have the transmission oil cooler inside the radiator so the trans cooler lines are routed right on top of the radiator fan shroud. You can get away with removing only the top line but be sure to have replacement trans cooler line connectors handy and extra "clips". Dorman brand works ok. Also have a quart of DEXRON 6 trans fluid if any is lost during the repair. And top off trans fluid using factory instructions.
Also, it is important to verify what brand of fan is in the car now before buying the GM fan "motor/blade" only part, as it will only fit into a GM fan "shroud" part. They are available seperately.
I was intimidated doing the 1st fan job, but it is pretty straight forward if you follow directions. Lots of details but all important. Here is a lengthy thread regarding fan stuff:
There are a huge number of fan threads with great info on repair/replacement of the cooling fan but I am still left with the question, why do the resistors fail? My 2012 eco at 210k and 11 years of service has the original fan and it's working fine. I was hoping to install a gm fan today. It is...
