ugh i cant get it to work!

 

Wonder why that chart states heavy duty cooling and tranny cooler???????, when towing more than 2000lbs.

 

Here's a U-Haul Class II (3500lb) that hides well, I think and it will handle more weight than I care to tow with the XJ. $109, IIRC, and shipped next day.

 

X2 on cooling system being in tip top shape.

 

sent you a PM sir, prob much easier than discussing back and forth in this thread

lol oh believe me the car i'm towing is my baby (pic below) so i'll be checking everything is in perfect working order before I leave and of course along the way, I've researched that I should have my tires @ max PSI, i'll be installing an aftermarket oil cooler and i'm going to have my coolant system flushed out to get any rust or anything else out of there and running clean. Is there a reason I should run premium vs. regular octane? I also planned on getting the uhaul class III hitch or the hidden hitch class III.

 

At 8.8:1 compression I wouldn't think the XJ would need premium but it certainly wouldn't hurt using it while towing.

 

Just personal experience on the fuel octane. One reason I purchased my Cherokee in 1996 was that it was the least expensive SUV that could occasionally pull my 3500+ lb. boat and trailer. I hate using anything but regular gasoline; however, I found that when pulling my boat, I experienced more spark knock than I liked to hear. I also use premium fuel when on the trail.

One other item. Have your rear brake shoes adjusted properly.

Are you sure that you don't want to rent a car trailer as opposed to a dolly for her?

 

I think uhaul rents out car trailers. It's AWD so it can't be towed on just 2 wheels so I would need their larger car towing trailer. Unless you know of somewhere else I can rent a car trailer?

 

Better check the weight of that UHaul trailer.......UHauls are built ULTRA heavy duty, thus they're very heavy.

 

After all this discussion and finding out the tranny cooler is not too expensive, I'm completely sold on putting one in. I'm being lazy here, will have to search the posts, but does anybody have a handy link for the install process?

Also, what adjustments should be made to the rear brake shoes?

I'll only be towing about 2,000 lbs, but it'll be mostly full time, and she's my baby so am keen to keep everything ship shape.

 

I thought switchin around from regular fuel to premium fuel could screw up your engine?

 

False, just another Internet myth. Higher octane gas is simply less likely to pre-ignite (knock/ping) than low octane gas. Very few engines need/require it and it's probably not needed in the XJ but certainly wouldn't hurt if used when towing.

 

^^ agreed i switch between octane's of gas all of the time i always get the highest octane gas that i can afford at the time and i have no issues

 

I got a class 3 curt hitch. Stays close to the bumper. 5,000lb rate.

 

I concur. Many contemporary engines use a knock sensor that when spark knock is detected, the computer will retard the timing. With high octane fuel, manufacturers can advance the ignition timing and increase compression to make more power.

The trailer towing section of my 1996 owner's manual reads inside a caution box, "When pulling a heavy load or driving a fully loaded vehicle use a premium unleaded fuel to help prevent spark knock. If spark knock persists, lighten the load. Otherwise, engine piston damage may result."

Most of the time with normal driving, high octane is unnecessary.
