Working up the nerve to do a DIY glycol exchange on my 2021 400. Luckily I don't have to do a change from Century to Rhomar. Just swapping out old Rhomar for new. If anybody has done this on a 400, any tips? I've read the great writeup that
@ScottG did but I'm wondering if the 400 has anything unique to it I should be aware of. I also had a few questions below:
- How do you know when you've pumped all of the old glycol out?
- Would a battery-operated submersible pump work just as well as a hand pump? Youtube videos I've seen show them being used so I assume yes?
- Some Youtube videos show the expansion tank completely removed to access the inlet and outlet pipes more easily. Is this recommended?

@johnfconway The shop vac is what confused me in these threads. @ScottG simply used a hand pump to push new fluid through the system and the videos I've seen on YouTube show a submersible pump on the inlet side. What's the purpose of the shop vac if you already have a pump pushing fluid through from the inlet?

@ScottG So in your experience was the hand pump sufficient enough to do the job? I'm tempted to get a battery-operated pump from Harbor Freight for $12 but I'm worried it won't have enough power to push the fluid through.

BTW my Alde has worked perfectly since. No issues, no fluid loss, and hoses look good. I did add the ground to the Alde case but who know if that helps reduce corrosion risk; it was just easy and recommended.
Good luck and flush well!

Feeling much better about the process seeing as many of you have done it already and it seems to work. Plus I don't have to flush old Century out as I'm just replacing Rhomar. NOT HAPPY about the ridiculous cost of Rhomar though. Anybody want to be a 5-year guinea pig and see if your Alde corrodes ?

So part of it sounds like a confusion over the US and European variations of the Glycol.
