Very innovative filter system! Need a job at Mopar?
We'll begin by covering the discussions from the chats 'o yore:
Cherokee SRT8 Forum - View Single Post - [COMPLETED] - 4/18/07 SRT Q&A Session
We'd like to re-iterate that "we know exactly what the issue is and are working to push the issue UP the proverbial mountain to get you guys a solution".
We hope all of our enthusiasts (aka YOU) understand that we are not spending our time here trying to put a spin on the situation. We are limited by our management and corporate structure (read check & balance system) about what we can discuss on this forum.
We are telling you all we can right now. We
want you to love your cars and enjoy them as much as we enjoy developing them.
With that being said... if you have an SRT8 LX vehicle that was built in the second half of 2005 CY or 2006 CY, you should check your coolant bottle for abnormal coolant (i.e. cloudy, scuzzy, floaters, ammonia smell etc). If you find an issue, please take your car to the dealer and show them the previous post in the link above. When they call DCX, they will be told to perform a flush and fill and add an additive.
Important Notes / Other Answers to Your Questions:
- The dealer
must perform a flush and fill per the LX service manual, not just a drain and fill. For those of you that have had the dealer service your vehicle and the issue come back, it sounds like it was not done properly. Once a full flush has been performed, be sure to have them either flush and fill with Mopar Coolant w/ additive or flush and fill with Zerex G-05.
- The filter idea is a great one, but would be difficult to implement in the field. We've shown that the flush and fill when properly performed removes the majority of the solids and with new fluid fill, the system stabilizes.
- The white substance in the coolant is Aluminum Hydroxide. The ammonia formation is possible in
ANY HOAT coolant, which is the standard in many if not most vehicles today.
- If you want to read more about this phenomena, check out papers available out there, one of which is ASTM 1546-962X and articles from the Radiator Reporter.
