Looks to me like its OAT based..... https://www.trpparts.com/media-center/2020/trp-extended-life-coolant As posted above, can you back up your 'OAT coolant is junk' statement?

Dexcool has always been controversial, and I'm not sure if it was a poor product to begin with, or if GM did not do their homework on preparing their engines (e.g. intake manifold gaskets) to coexist with Dexcool. 3 years ago I bought a 2002 Corvette from the original owner that still had...

I was hearing the noise anytime fuel was not full and it was dry outside. I would not hear it when it was raining or when our 5th wheel was attached. When the repair was done in December to the truck, they had to remove the bed. When they reinstalled the bed they forgot to attach the fuel / DEF...

I did and I too noticed some statements in the description doc that seemed to bleed over into the 1500 system (which I had on my previous RAM). Here is the section on filling the system.

As in many of your posts, you somehow always know more than other members, the factory, and possibly Engineers. I uploaded RAM documentation - and while I understand it could be incorrect I'll ask the same courtesy from you. Please backup your statements with official documentation. If you're...

I'm in no position to argue, but the RAM Service Manual document I uploaded in my earlier post clearly states that the 3500 is a closed system.

You can't do a full dump unless you deliberately go through the process of drain and refill again with nitrogen. There is a minimum retention pressure that stays in the system. Yes. I purchased a 3 day subscription from Tech Authority. I attached the section describing how the system works...

I don't think its even possible to release all the pressure from the bags outside of physically opening up the pressure lines. It's a closed nitrogen filled system and I'd be surprised if RAM would allow a full dump of the bags.

In spite of the cold I couldn't wait and did some playing today. At this point I'm feeling like I hit the jackpot. I've only put on about 10 miles but there is a definite difference. In my opinion, this truck now rivals the GM HD trucks, which I believe have the best ride of the big 3 (although...

The local dealer had a loaded Laramie 3500 CC SB SRW with air suspension so I went over and looked at it today. Both bags were relatively firm and overload rubber cushions were about 5/8" away from the lighter springs. After that I went home and using a floor jack lifting the hitch receiver on...

I may play around with this tomorrow. When you say 1/2" are you referring to the frontmost cushions vs rears? On my truck the rear cushions on the overloads definitely touch before the front cushions. Its been a few years since I posted my experiences. I had hoped that by this time I'd have...

AH64ID....thanks for the info. This is a perfect time for me to do some checking as I just filled with fuel. Mine is Crew Cab Standard Box...everything factory including stock 20" wheels and tires. No Rambox. Crawled under the truck this evening and saw the following. I have 1/2 full def and...

Thats a great video for sure! My thinking is that you're riding on air because of the load you have in your truck, but hey, that's just my opinion. I'd be more than happy to be corrected by an engineer from RAM. Thanks much for taking time to put the video together!

I started a thread on this back when I purchased my '21 (link below). My experience and understanding of the air suspension aligns with what BilletWilson is saying. Others who participated in that thread seemed to see the same. The thought is that when the truck is empty, the rear of the truck...

For the 3500's, air suspension and rear tire pressure both play big parts in ride quality. When I test drove 3500's I always asked the sales person if I could drive alone. I carried a tire pressure gauge with me and after a few blocks I pulled over and aired down the rears to 35 lbs. Driving an...
