Fan Clutch cooling question
I will be towing a trailer in 2 weeks. It weights around 6700 dry. The Armada (06) towed it just fine last time until I was climbing a hill at freeway speeds...then the engine temp and tranny temp climbed quickly. We stopped in the next town and had the coolant checked and were assured that is was doing the job. We serviced the tranny and rear diff and changed the engine oil previous to the trip.
After doing a little homework, I've realized that I didn't manually shift out of overdrive...however, my previous Armada (05) traveled this same route with the trailer with no problems. This had me wondering if the Fan Clutch was doing it's job.
Tonight I checked it with the engine hot and it turns fairly easily. Would that indicate it's bad...even though the Armada has never run hot without a trailer on it?
The engine temp and tranny temp do not rise while driving in the city in high 90's and 100 degree temps. (no trailer)
So my question is, Could the Fan Clutch be doing an adequate job for it's daily routine of running the wife an kids around town...but not pull enough CFM when working hard up a hill with a trailer?
Thanks in advance for any insight.
If I had all the money I've spent on cars.... I'd spend it on cars!
