Fully AUTO AC control upgrade (HH4) | Mercedes Sprinter
Вставка
- Опубліковано 6 чер 2024
- Here in the US, the Sprinter comes standard with what Mercedes calls Tempmatic AC control (HH9) where the fan speed and air distribution needs to be adjusted by the driver.
In this video, I am going to upgrade to Thermotronic (HH4) which is a fully automatic AC control where the van automatically adjusts fan speed and air distribution to achieve the set temperature.
for this upgrade I am using a kit from KUFATEC which comes with all the necessary parts.
I do have one of these kits for sale. Please follow this link for more info:

Great upgrade as usual. I have another for you to look at if your interested, the bathroom vent push it up and go up on the roof and look at it see if your foam seal around the lid is still attached mine was foam held on with double face tape that the heat made it not stick and was bouncing around on the fan.
Thank you for every single video you have made! Seriously, THANK YOU! Unfortunately, with the Revel, you have the opportunity to make 50 more upgrade videos!
I would like to remove the top half of the shower and install a folding countertop, along with designing a pull-up shower curtain since I rarely use the shower. Additionally, I want to completely redo the plumbing with a simpler, more practical solution. I'm also looking to pull out all the large wiring and install the Ecoflow system or a 24V system, removing the second alternator because it's unnecessary and I believe it stresses the engine and affects the MPG. The motor and its parts weren't designed for a second alternator, making it a potential hazard waiting to happen.
Winnebago's approach lacks common sense in many aspects; they didn't do anything correctly. Everything they touched was wrong, cheap, and easy. I just watched a video on 27North, and you will never see a video of the Winnebago Revel factory floor. The 27North video shows a real quality factory-made van, which is the polar opposite of the Winnebago factory. Everything at 27North is engineered for a reason and uses the best possible parts. It's perfection.
They haven't had a single van return for issues, unlike Winnebago, which likely has problems with every Revel van made. Their customer service is practically non-existent, operating only a few hours on select days, with one person answering the phone. This shows a lack of care once the van leaves the factory. God forbid you need dealer service; there are fewer than five trustworthy dealers in the entire country. It's very sad, but we're all stuck with them, so keep making the videos to help us fix their junk. Thank you!
thank you for your comment, I really appreciate it. I do agree that Winnie's build quality and QC leaves a lot to be desired, however, I think at least the overall design and engineering is solid. the aluminum exoskeleton of the upper cabinets and shower and pantry and around the battery bay isn't something I have seen in many other vans and certainly not what any of the small builders can do. Of course this is no excuse for sloppy assembly and for sure not for a van that has a list price of $200k+
With all the modifications you have on your list, it might be better and in the long run cheaper if you build your own van from scratch. 27North are for sure nice vans but they cost quite a bit more than the Revel.
One thing you should not need to worry about is the 2nd alternator. The MB engine is designed for a 2nd alternator and in fact the bracket it attaches to is an OEM Mercedes part. In Mercedes speak, it is called option 'N62 PTO at front with bracket for extra alternator'. Of course running the 2nd alternator impacts MPGs, this is simple physics, you need to put power in (burn diesel fuel) to get energy (Watts to charge the battery) out. I think the 2nd alternator is rated at 280A at 14V, this equals to about 4000W or a little over 5hp. and this is when it runs at full output - which it mostly don't as the batteries cannot be charged with 280A for extended periods. So really, these 5hp max, don't put a lot of extra stress on the engine and even if you remove the 2nd alternator and have the primary one charge the batteries, it would need to burn just as much fuel. at the end of the day, you need a certain amount of fuel that the alternator converts into battery power. a 2nd alternator has a little extra mechanical resistance but that is neglectable.
You’re incredible! Thank you for your wisdom! I would like to upgrade the wooden bed slats to something that will span the full width of the bed. It seems like my hips hit right in the center where they join. If I remove the under-bed plastic, it would be nice to upgrade the center “lump,” and I don’t want to do it without your engineering wisdom first! Also, have you thought about having your own Amazon page with all your recommendations for parts, products, and upgrades? Thank you so much!
@@ShawsUA-cam actually, I did upgrade my bed for the same reason you are having. hip pain in the morning caused by the center hump. I fixed this by buying a new mattress. I went with the one from RoamRest (medium firm). it is not super cheap but totally worth the money. I did not make a video about this upgrade because there isn't much to it. toss out the old one, drop in the new one.
I'll think about the Amazon page. Indeed I get a lot of questions about the parts and while I don't want to be a channel selling things to my viewers, an overview on Amazon might be helpful.
Nice job sir.
Ich beneide Dich um Deinen Mut in die Elektronik des Fzgs. einzugreifen. Ich hätte da Bedenken wg. eventueller Fehlermeldungen im Nachhinein. Es macht sehr viel Spaß Dir zuzuschauen wie begeistert und penibel Du an Deinem Sprinter handwerkst. Ansonsten ein Top-Video !!! Herzlichen Dank !!!
dankeschön. Die Kufatec Sachen sind ja prima dokumentiert, da sollte eigentlich nichts schief gehen
Ich habe Dein Video zu dem Hupeneinbau gesehen. Der Einbau eines Relais kommt sonst in keinem ähnlichen Video vor. Teile Deine Argumentation pro Relais zu 100%, würde es auch gerne in meinem Sprinter Bj. 2022 so einbauen. Für Dich alles Gute !!!
Very good video.
One question where did get the carbon look trims from, thank you
thank you. The carbon trim came standard with the Winnebago Revel. I think it is something Winnebago added.
