#9 of 51 Towing and transmission coolers???
Aug 24, 2008 (4:57 pm)
Does any one know if the Siennas have transmission coolers already installed (going to be towing) or are they even required. I dont see any mention of them in the owners manual, so want to be sure. We will be towing a fairly heavy trailer. Had to install a cooler on our Odyssey. We have a 04 AWD Sienna. Wondering if the AWDs need more cooling etc. Any help appreciated. Thanks.

Yes, up until the 2007 model year, the tow prep package was standard.
For 2008, they made this an option, but most vans in my region still got it.
I know 07s had them standard, though.

I purchased a Reese type hitch from NAPA and installed it myself on my 2006 Sienna AWD. Fairly easy to do since the nuts are already welded into the frame. Just a matter of bolting it on with four bolts. The right side is a bit of a pain because the exhaust pipe is in the way but it can be done with the proper tools. Bought the wiring harness through Ebay and it was a snap to install. Only had to remove both tail lights and the rear panel below the tail gate to connect the harness.
Pulled a 1200 pound tent trailer to PEI and back last month. It was so easy I had to look back at times to make sure the trailer was still there. Great towing vehicle and I still got 18.5mpg on the trip while towing the trailer.

That sounds good, I know towing kills mileage.
I had a 1998 Forester that averaged 25.1mpg over its lifetime, and I got about 18mpg on one tank while towing the whole time.
I'm sure the big V6 simply handles the load better.

Thanks for the reply. Between you and the popupexplorer.com crowd, am definitely going to get the WDH (Looking at the Reese mini 400) and the air bags. We had our local hitch guy put a DrawTite on and with the bikes on the receiver hitch, it will drag on a steep driveway so definitely need a little lift there.
Now if it will just cool down a little, it will camping around here a little more bearable.
#14 of 51 Tow Prep after market
Mar 11, 2009 (4:51 pm)
I recently bought a Sienna 2009 XLE Limited with the EVP-2 package. I was also understanding that the van came with the tow prep (engine cooler, transmission cooler and wiring harness). This was not the case. The vehicle does not have the tow prep and the dealer is now telling me that it cannot be put in after the fact. I have researched the web and cannot find any after market information for this van. Can this be done after market and will it void my warranty?

It was standard in model year 2007, but in 08 they made it an option, a couple hundred dollars or so.
I don't see why it could not be added, though, isn't is basically an oil cooler?
#16 of 51 what is towing package

I am looking at a 2009 Sienna. I am trying to decide if I need the towing package. Does anyone know if it is any more than the wiring harness and the hitch? For $220 it would seem no additional coolers, such as transmission, would be included but I have been unsuccessful in verifying.

I have been looking at 2009 Sienna XLE's and LE and have had two dealers (Fred Anderson in Raleigh, NC and Mark Jacobsen in Durham, NC) both say the 2009's are not coming standard with the towing prep package. NEITHER DEALER could verify if you could put a hitch on the van. I guess it would be too much trouble to speak with the service manager to get the truth.
I noticed when building a Sienna on the Toyota web site that it states the tow package is not allowed. I'm confused.
Anyone know the truth on the 2009's? Do they have enough cooling to handle towing?
It is looking like a Honda Ody for me.

Not so fast...Honda's towing kit includes and oil cooler (for the trans, I think?) and a power steering fluid cooler, plus a harness and the hitch itself, plus labor.
I have the 2007 Sienna brochure, and here's what it says:
Tow Prep Package - 3500 lb towing capacity with heavy-duty radiator, heavy-duty fan, 150-amp alternator and power steering oil cooler.
I got it on my 2007, because I think those things are useful in other ways.
