Default 2001 Durango Fan Clutch Issues?

2001 Dodge Durango - engine temp is fine while moving, but temp increases when at stand still. Radiator was flushed and fluid replaced last week. Second fan does not engage when temp rises. Possible bad fan clutch??? How do we replace it?, or does anyone have any other possible fixes???

the electric fan (i believe this is the second fan you refer to) does not engage until you hit 210 or 215 (or with the A/C turned on)

you can determine if you have a bad fan clutch by opening the hood (with the engine off of course) and spinning the fan by hand, more than 1/2 a turn the clutch is bad, my clutch with 92xxx on it spins about far enough to put the next blade up (just for reference) if it spins somewhere in btwn the two i would say it is going bad, and replacing it wouldnt be a bad idea (not necessary, but cannot hurt)

Easy way to test your efan. Open up the PDC in the engine bay. PDC located right in front of the master cylinder next to battery. Look for the relay marked a/c compressor. All the relays are basically the same. Remove one fron another location and pug into the compressor spot. If the fan comes on, you have a bad relay. If no action, you can crawl under the D and look for a green colored connection to the efan. Unplug the connection and run a hot wire directly from the battery to the plug. If the efan does not start with the direct feed, you need to replace the efan.

Not true my friend. I had the efan go out on me and it caused an almost major issue. It was last summer and stop and go traffic going towards bronx zoo. The D was doing fine on the cross bronx until we hit traffic. Stuck in traffic with the A/C on w/o the efan caused the D to go into "limp" mode. Temp was thisclose to right hash mark. I had to turn off the D and let her cool with the wife and kids in the D. Glad I found a shaded spot for that. Waited until she was cooled enough to drive carefully back home. Needless to say the day was shot! LOL! Found out the efan motor was DOA so swapped it out and put in an FAL controller, no overheating problems so far! (Knock on wood). (Knocking on head).

under normal conditions the efan being bad wont be noticed bc the efan does not go on until the car starts to overheat (210 or 215 degrees) the A/C was also part of your issue, mine has never run unless the A/C is on, my temp never climbs above the half way point no matter how long i sit in traffic. (the only way a bad e-fan would manifest itself as a cooling problem is in your situation where you have the A/C on which throws heat out in that area)

Exactly! I had the a/c on during summer in stop and go traffic. It was doing fine on the expressway until I hit traffic. Then the problem manifested itself. So we're basically saying teh same thing?

from reading his post, and him NOT mentioning the A/C being on, i would say the fan definitely needs to be replaced, but that he might also have a bigger problem with his cooling system, and that he should look into it before he causes problems byoverheating the truck, that is all.

2 more things to check on a mechanical fan clutch are to grab it and rock it forward and backward. If there is any play it is bad/going bad. The other would be fluid leak. Any fluid leaking from the fan clutch is bad.

You know what? That's true. I just assumed the a/c was on due to his posting at the end of june. That's why I used my experience. And what are you doing on here??? Should you be in lab or something???
