Capital AL I occasionally tow my ATV with a few other things. The trailer is about 2000 pounds. I have the 3.7 engine and temperature always stays the same, 1 mark under half way, regardless of city or highway driving.

2005JGC Sounds like its pretty normal for the 3.0 guys.

I know my temps will creep up just lugging birtha up a mountain pass trying to keep up with the rest of the party doing 65-70. I do not recall it ever working up past the middle line though (4.7l gas here, also not towing anything except poor gearing for the tires and the heavy jeep full of camping stuff).

My A/C does work but is less cold while stopped for sure. The fan speed is high but I can not tell if it is maxed. I believe there were some posts here on the forum on how to test.

Yes, I did! And I actually check the level of the fluid regularly now. Changing the pump on the CRD is a royal pita.

Chirpz No... only when going up a steep grade. My trailer is only 18' and my loaded gross weight is around 9,800...it varies a little.

jamief when empty I'm just below half. Towing a 5000lb camper it goes to one mark above half. This is with the 3.0L CRD

Planetcat My hemi wk and my dodge cummins 2500 pickup truck both exceed the normal temp range when towing, but mostly in stop-go traffic and up the mountains. Even if the weather is in the 80ís it happens. Mostly towing my 4500 lb boat. I would be moderately concerned towing a 21í ski boat for 5 hrs in 110* temps, but less concerned if its all flat roads. Like nvrdone said, 240* would be hot but not out of the question. That would be my max before i pulled over though.

nvrdone1 I tow a 19' cuddy cabin boat that is 4200# on the trailer. my temp gauge normally runs right at the 1/2 mark when not towing. a laser thermometer pointed at the t'stat housing shows about 215 deg. when towing the gauge goes slightly above the 1/2 mark & the laser thermometer shows 240 deg. according to the dealer, this is well with in normal range. I did replace the radiator, water pump & hoses last year. its a 5.7 hemi

terrasmak Mine is just above half when towing my open car trailer with a 3000 pound car. /50k miles ago it would stay on half.

I've never had to do anything with my power steering, yet.

T1m If you're asking me, I really didn't notice any difference in the behavior of vehicle. I did press the "tow" button that turns overdrive off as I was going through hilly highways to Nashville. The person behind me, who was driving the U-Haul, said she saw her car go in the air a couple of times - we had two-way radios.

The towing package also includes a transmission cooler, which I think is incorporated into the AC system. Like I said, I saw no difference in my vehicle's behavior.

T1m I've only towed motorcycles and a car with the two-wheel u-haul thingy. They always felt like a feather behind me.

For the car, I towed it from New Orleans to Nashville. This was in my 3.7 Liberty with the towing package. it was easy - peasy.

I didn't notice higher temps when I towed.

Edited to add: I did use premium fuel for the tow, because I read it burns cooler.

Is your temp higher when towing?

I noticed recently that when I tow my 21foot ski boat the temperature on the gauge goes to the first dash past half whereas it normally stays right on half or one dash below.
I don’t think I ever heard the fan coming on at full speed.
In the recent past I swapped the power steering pump that also drives the fan so I am wondering if there could have been some damage to the fan.
Anyone care to share their experiences? Was planning to tow for about 5 hours straight into 110F temp area in July.
