Three problems related to engine cooling system have been reported for the 2013 Jeep Wrangler. The most recently reported issues are listed below.
The oil filter housing/cooling assembly is plastic, cheap, and located right in the middle of the engine. Mine, along with many other Jeeps of this make and model have them fail well under 30,000 miles. This causes massive engine oil loss which in turn causes engine damage. This is a huge rip off considering the part costs ~$500. Chrysler should fix this immediately on all Jeeps.
No heat! clogged heater core! grit and slime in dirty/discolored oem coolant (10 yr/150k mile rated). Never touched or added to, unless undocumented by dealer. This is our family vehicle that my wife/kids use daily, and it is about 10f here in vt right now. Very common Chrysler issue apparently and dealer does nothing but attempt to flush multiple times which does not solve the problem and is a huge inconvenience! I am still under 5 yr/100k powertrain warranty, since when is cooling system not part of power train? heat was reduced last winter, this winter virtually none. Dangerous to constantly clear the windshield with no defrost! this needs to be a recall.
When changing the oil . When you remove the oil filter there is a plastic part on the shaft in the oil filter housing. This is a valve that controls the oil if the filter gets gummed up the presser causes this valve to open so that the oil will still flow if the filter is clogged. This plastic valve breaks during normal oil changes. To fix this 10 cent part you have to buy a whole new oil cooler unit at the cost of $237. 00 also to have the dealership fix it your looking at $800 plus for a 10 cent part. Jeep changed the oil cooling filter unit in the 2014 models. This also happens not only in the Jeep jk v6 but also in Dodge chargers and any v6 models that use this same filter oil cooler unit. Part # 05184294ae number on image: 1 category: 3. 6l gas; engine msrp$237. 00 price may vary by dealer adapter engine oil filter seems like a ripoff that you can not buy a 10 cent part but have to buy a $237 unit that is not needed.
