You keep mentioning Water-Wetter. How certain are you the product is safe? The 2014 Jeeps are using a new coolant type called OAT. It is not your regular antifreeze and is brand new to the Jeep arena. Many forums indicate that OAT reacts with Water-Wetter and creates a slush. Please be careful!

The only problem I have with the car is keeping it cool, when towing. I live in Australia and tow a 2.6 tonne caravan. The Jeep does it with ease and returns a fantastic fuel mileage of 13.5 litres per 100 km, when towing. This is it all hooked up and ready to go. BTW I removed the "grill" under the nudge bar, to get better air flow. On the highway and over small hills the engine temperature is fine. Once we start climbing a range, the temp gauge rises almost to the red area, then drops as quick as it goes up, when going down the other side. I'm wondering if any one else has this problem? I suspect a bigger electric fan would help, or, an addition fan in front of the radiator area. Any idea's out there? Cheers, Ron

What speed are you trying to maintain while climbing the range?, are you pushing to hard?, speed will make a huge difference to engine and trans temps, you need to be realistic about the speed you try to climb at

OAT is nothing new. Redline says its compatible. BMW has been using OAT for years. However, OP should check it out.

Re: Cooling problems on hills

What gear is it in on the uphill? You could try sport mode and downshifting a few gears. My old jeep has an overdrive off button just for that purpose.

As I'm towing a caravan that weighs more than the Jeep, I keep the speed down, lower gears and try to maintain at least 2,500 rpm.

At the same time I monitor the transmission temperature, and drive accordingly. Once I'm over the hill, top gear and foot off the "gas peddle" allows the temp to drop quickly back to normal.

Cheers,
Ron

Re: Cooling problems on hills

The jeep should be able to pull that relatively light load no problem especially in that low osa temp. I'm patiently waiting the ram eco diesel and I need it to pull 6,500 in 100* f oat.

Re: Cooling problems on hills

Go to your dealer and say you are concerned about the water temp. Dont mention towing. Just say it gets to wherever on the gauge.

Again gauge is probably not linear.
