Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

So when I order a new cooler part, how would I know if it has the newer design part by "Hengst" as you indicate? Tha newer design looks much more durable than the previous design. If I am going to spend the money I want to make sure I get the latest design.

You would want to order this part number: 5184294AE

Earlier I messed up the years, the design change started on the 2014 pentastar engines, 2011-2013 have the Hengst cooler.

Thank you for that information. I ordered one with that part number for $158, shipping included. Is it best to go ahead and replace the whole thing or is it ok just swap out the relief valve?

Either way, once I have it a unit to work with on the bench, I plan on coming up with a suitable replacement/alternative for the pressure relief valve for when it breaks again.

Again, I really appreciate your help.

just swap out the relief valve, otherwise you will need new gaskets/o-rings. i designed my own also, aluminum, i can share if you shoot me your e-mail

Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

I wanted to give an update. I ordered and received a new oil cooler part (which is the only way to get the plastic part I needed) and after reviewing how the little plastic part worked, I thought I might be able to use the old broken part. So I tried it and it worked. To remind everyone, the little plastic part that was broken was a pressure relief valve. It is there in case the filter get's so plugged that oil can't pass through it. So here is what I did:

I removed the oil filter and placed the spring inside the round plastic tube in the oil filter housing. I then placed the broken plastic part which was just the end with the nipple on it on top of the spring so both of them just layed in the tube. I then took the oil filter cartridge by itself, not attached to the oil cap, and slid it over making sure the plastic nipple aligned to fit inside the end of the filter. This seals the end of the oil filter cartridge. I then put the oil cap on and slowly turned it so I could hear when it snapped into place on the filter. I finished tightening it down and that was that.

However, I wanted a better solution than using the broken plastic part. I thought I could either design a replacement part or come up with an alternative using something already existing. One member on this forum actually sent me a design I could use to have a machine shop make parts. After some experimentation, I found that I could use a machine screw to accomplish the same function as the little plastic pressure relief valve. I think it is a #4 machine round head screw and about 1/2 inch long. The round machine screw is small enough to slide inside the spring and the head is big enough to fit inside the oil filter cartridge end to seal it. Because it is round, it tends to right itself and seat inside the filter to make a good seal.

I slid the screw threads inside the spring with the head facing upward. I then placed the spring (with the screw inside) into the round tube in the oil filter housing. I then put the oil filter cartridge and cap on the same way as described above. The round head allowed the screw to align correctly every time that I tried it to seal the end of the oil cartridge. Even though the spring and screw lays inside the tube to one side, it seems to be self aligning in the middle of the oil filter cartridge end hole.

Basically, this is a 10 cent solution for a cheap 10 cent plastic part that would cost you about $500 at the dealer to fix. I know some of you out there will say this is stupid and no way would you ever do this. I understand ... I am not a mechanical engineer, but this seems to work very well in my opinion.

I will post follow-ups after future oil changes to let you know if it continues to work as expected.

Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

Great to hear there was a happy ending to your situation. I found this thread last night after searching for suggestions for what to do when I discovered some small broken plastic pieces inside the center cage of the filter housing. I noticed the plastic pieces when changing the oil on my 2013 Jeep JKU. Unfortunately, it appears the small plastic stem that sits on top of the center spring, inside the center coil is non-replaceable. I had to have my Jeep towed to a local Jeep service center this morning to replace the entire filter housing. $227 for the part plus another $567 in labor. $794 plus 8.7% tax! I'm told I would be getting the newer version of the 3.6L Pentastar oil filter/cooling assembly. I can't get over how small, thin and fragile the plastic stem is. It's no wonder it eventually broke. I've have only 30K miles on my Wrangler but I religiously change the oil every 3K miles or 3 months. That's roughly 10 oil changes since I've had my Jeep. Learned a tough lesson on this one.

Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

My plastic stem in the oil filter cooler was fine, it was just the little plastic dome nipple that was inside that stem that broke. Before I came up with the machine screw idea, I had ordered a new oil cooler part and was told it would be the new designed cooler part, but when it arrived, it was the same as the old original part. Since it was not going to be an improvement and I would have the same problem in the future, I decided to find a work around and sent the part pack for a refund.

It seems like this is a terrible design flaw using plastic in such a critical parts. Why deviate from what is standard in the industry and reliable?

Wow! Talk about some great luck getting the old part instead of the new one! And getting your money back! I was not so fortunate. I know what you mean about sticking with what works instead of some new inferior design! What's also interesting is that the dealer service rep told me that they have had numerous Jeep owners in for oil cooling/filter housing replacement for the very same problem. You'd think Chrysler would at least offer some kind of recall replacement. I suppose it's another example why they're being fined $105 million dollars by the NHTSA for not being more proactive with recalls. I guess the engine oil cooling and filter system isn't a life for death matter. Although I'm sure they're making bank on parts replacement. Maybe it was intended to fail so guys like me who don't have the time to replace it themselves will purchase the part and boost Chrysler profits! Now I'm getting paranoid!

Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

I think this is a serious problem for these engines. This engine is used in so many different models of vehicles, so there are a lot out there with this problem. And for those that don't do their own oil change (which is the majority), they could have this problem and not even know about it! It is just a matter of time before the plastic parts break. So it's not if it breaks , it's when it breaks!

I think Chrysler should have a recall to fix this problem.

Also, for those that have the newer designed oil cooler, have you had an issues like this with plastic parts breaking?

Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

I'm sorry to revive an old thread but I just had this same problem changing my oil today and did what acehiggy did. I just wanted to say thanks because it saved me 200+ just in parts. This is the worst engineering design I have ever seen for a part that sees so much stress and many heating and cooling cycles.

Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

Has anybody put a 2014 and newer oil cooler assembly on a 2013 engine yet? I went by the dealer and looked at both parts yesterday and it looks like everything will line up but they are different. I too did the machine screw trick for now until I have the time to pull the top of the motor apart to swap out the whole cooler assembly. I want to change over to the 2014 and newer design, I just don't want to be the first person that has done it! Looking for some peace of mind. Thanks for all of the help everybody! That machine screw trick was a life saver!
