Interesting video on this topic:Not sure this would be a good idea. Better to bite the bullet and get if fixed properly. Then report it to NHTSA Home | NHTSA so that there can be some pressure put on Chrylser to make this good.
And if the head gasket has been failed for some time, the block may also have been affected/cracked. A bottle of quick fix will never find that.
The Pentastar engine has these known issues that either grenade the engine prematurely or by the law of averages work out in your favor. Would think it would be unlikely to get hit twice by the same issue with two different engines but suppose it is possible since the root cause has yet to be diagnosed.Glad I found this thread. My 2018 Pacifica Touring L is at the dealership right now waiting for parts so they can install a new engine. It started with a solid CEL, rough idling, and a cylinder 3 misfire error code. The service department at the dealership tore the engine down and discovered a warped engine block. Fortunately, it's covered under the powertrain warranty, but once it's fixed I am wondering if it's time to punt on this vehicle. What other catastrophic failures do I have to look forward to? Will replacing the engine fix all the issues from the warped head or will other systems be affected and start to fail later on? Two years ago both batteries were corrupted and replaced (also under warranty) because of the ESS stop/start nonsense. I love this minivan, but these major problems are killing me. Can anyone who has had their engine replaced because of this warped head issue please let me know how their van is doing now? Thank you!
Also keep in mind if the system is under pressure. I've seen it show low and removed the expansion tank cap to find it at normal levels.I totally agree it's a seal system entirely but my dad even had two Brands new different make cars and after 6 months I'll pop the hood and they're even a wee bit low even with mine, it must just evaporate out somewhere somehow extremely slow at times.... Going back to physics all liquids revert back to some kind of a nitrogen BS at one point or another, lol
