2018 Toyota Tacoma 2.7 4 cyl just hit 20k miles. Out of 36/36 warranty.
Trying to figure out if my fan clutch is bad or not before I buy a new one. I’m getting different answers everywhere I look.
I’ve tested my fan clutch a few times. When engine is cold it has pretty good resistance. It does not free-wheel at all. There is enough resistance that when I stop pushing the fan stops spinning almost instantly. When engine is hot, there is slightly more resistance but not much.. From what I’ve read, resistance is good and normal.
The issue lately is that the fan has constantly been loud(howling noise, like the garbage truck). I’ve heard that this is normal for Toyotas so I never though much of it until a friend pointed it out. His tundra 5.7 doesn’t do it. It’s the same “howling” noise when you first start up, but it never goes away. Even after driving for 45+ minutes. Hot OR cold ambient temperatures.
This is when it all starts to make sense.
-My AC warms up when idling for more than a few minutes
-takes forever to warm up in the winter.
-I get 8 cylinder MPGs in a 4 cylinder(14.5 winter, 18 best during summer when rated 19/22).
-all YouTube videos of the 2.7 accelerating sound like a 4 cylinder engine, mine sounds 100% fan and 0% engine.
I’ve done 10k miles since I brought the truck. I could’ve sworn the fan wasn’t as loud as when I first got it. I know there are some other 2.7 owners on here. Can anybody confirm if this is normal?
