A couple of weeks ago, my wife drove her 2011 Volvo XC60 home and the radiator fans never turned off, until the battery was drained. I deduced from a little online research that it was the engine cooling fan module that was the problem.
Apparently it is impossible to buy this part by itself from Volvo, they want to sell you the entire radiator fan assembly. Which seems like more than slight overkill. I found a replacement part on Amazon (and also on eBay), and bought not one but two from different vendors as the reviews were pretty bad! A lot of “this worked for a few days” or only a few months, intermixed with “it’s been working fine ever since”.
A week ago I put in one of the replacements, and it seemed to do the trick. We even went on a road trip for a few days, and I brought along my extra just in case we had an issue. Well today my wife calls me to tell me that the car messaging indicated high engine temperature and to stop driving. While she was on the phone with me, the message went away on its own and she said the AC seemed to finally turn on (it apparently hadn’t turned on prior to this despite her pushing the button). She was right nearby, came home, and - without shutting the car off - I could see that the fans were running fine. Nonetheless, it appears that during her drive today they did not for at least a period. I proceeded to replace this module for the second time, and - upon firing up the car with the AC engaged - I can see that the fans, again, appear to be running fine with this module.
Does anybody have any general opinions of these modules, and am I throwing good money after bad? I know it’s a Volvo (the definition of this!). I am considering buying a considerably more expensive module from Gates that I saw some of the reviews mentioning. But, honestly, these parts (cheap $25 ones or $165 ones from Gates) all physically look the same. I’m starting to wonder if this is some el cheapo manufacturer cranking this junk out, knowing that people are going to be driving Volvos and having this problem, so flood the market with junk and make them chase “higher quality” by paying more.
