2014 WK2 5.7 Hemi oil cooler addition
 
As many may know the late model JGC 5.7 Hemi doesn't have an available oil cooler as an option from the factory. Except...it kind of does, if you're willing to go through the effort. No, you can't use the oil cooler from the 6.4 Hemi (it won't fit properly and would be a nightmare to modify) on the late models. BUT...there is an option.

The 2013 and 2014 (possibly earlier too) WD (Durango) has an available oil cooler for the 5.7 as part of the police service package. As it turns out, with some part swapping, all the parts which make this up are a direct fit for the WK2. It does involve some work though and it's not just an oil cooler. You need:

05038677AB Water pump. It's different from the stock one in that it has an outlet for the oil cooler inlet.

05038697AA Oil cooler tube connector (goes onto the water pump).

52014895AC Radiator outlet hose. Includes the hose from the oil cooler.

52014896AB Engine coolant to oil cooler hose. This one goes from the water pump to the oil cooler. Includes a bracket to the engine.

06509216AA Bolt. For the above hose.

04893310AA Engine oil cooler. Mounts onto the existing oil filter adapter. Includes seal and extended oil filter fitting.

That's about it. Seeing that it needs a new water pump, this isn't exactly the easiest or cheapest modification in the world, but it's bolt-on and doesn't require cutting hoses or doing strange things to make it work.

Just an FYI.

Interesting, what's the totals cost for all of these parts?

Why not go with an air to air cooler from someone like Setrab, an oil filter adapter and some braided line from Earl's??? Less stress on the radiator which might not be able to handle the load. Does the police package for the Durango come with a larger radiator???

The radiator is the same as in the GC, police package or not.

The disadvantages to an air to oil cooler on a daily driver are twofold:

1) They tend to over cool the oil. You want your oil to get up to around 190-195 at the sensor, meaning it's a bit hotter elsewhere (210-230). This is so you boil off condensate and other volatiles that form in the engine during cool-down.

2) The factory coolant-to-oil cooler is inherently safer. The only hoses are coolant hoses and generally under lower pressure than oil within oil lines. If you lose a coolant line, you can stop the vehicle and will likely not suffer catastrophic damage unless you weren't paying any attention. If you lose an oil line on an air-to-oil cooler your oil pressure will almost instantly go to zero and if you aren't at idle (when you're least likely to lose it), you will very likely have wiped bearings or at least significant damage before you can stop.

Many adapter plates have thermostats in them. If installed correctly chances of losing an oil line for an air to air set up are very rare. I am guessing this set up is for towing and not playing Baja 1000?. A OEM radiator line has a greater chance of failing or coming off than a Earl's line.

Very interesting.

Is this the same kit?
