Hi this is Mike & liz, We are looking at the Kia Sorento to buy and want to know if the factory fitted towing kit has a Transmission Oil Cooler already fitted. We will be towing a 15 foot Pop Top caravan. Regards.
The UK spec diesel auto Sorento has an oil cooler for the transmission fitted as standard. I checked with KIA technical as to whether additional oil cooling was required for towing and was told that it was not necessary as the existing cooler was sufficient.
Towed my 5 berth caravan to the South of France last summer during 40 degree C temperatures and everything was (and still is) fine.
I guess a more frequent oil service on the autobox may be needed but that is not a problem for me if it saves the 3.5kGBP cost for a new box.
As a tow car the Sorento is superb, so don't be put off by the badge snobs!
