I've seen other videos where they would add a resevoir that constantly bleeds the sytem so you don't have to keep doing this every once in a while. Do you think that type of system is efficient/reliable?
I do! A secondary reservoir tank for the supercharger cooling system is ideal but not everyone wants to add additional lines and tanks to their engine bay.
True. I’m thinking of adding an oil catch can to my system. Luckily I can fit both systems since one can go near the shock tower on the driver’s side and the other up in the front near the radiator.
Amazing 👏🏻👏🏻. I have never done it before in the past 3 years, So how many times should I do it? to remove all the air? like every 3 months or !! and for each time how long should i keep the pump running on ? thanks
I cover the pump run time in the video, but as far as how often you should do it really depends on how you are using the car. If you are drag racing or road course racing, you should check it at least before your event for any bubbles. If you notice the car substantially losing power under heavy use, it’s not a bad idea to check it when that happens. I’ve seen some systems with little to no air at all, and I’ve seen others with huge bubbles for quite some time.
For this process, how would it differ with the addition of a s/c coolant expansion tank? I’m currently in the middle of installing a upgraded supercharger heat exchanger and a supercharger coolant expansion tank, and with the addition of the tank, I’ll lose the hose with the fill port for the coolant, and the new “fill” port will be the cap of the expansion tank.
My understanding of the coolant expansion tank is that it is no longer a “closed” system, and simply opening the cap on the tank and letting the pump run would allow the air bubbles to circulate through. Essentially the 2-liter bottle in this video is a temporary “expansion tank” so all you need to do is run the car, squeeze some hoses, or run the pump relay the same way until you see bubbles in the tank.
Yes, it is impossible to get all of the air out in one shot, but the timeline is always going to depend on the use case for the car. If you track the car frequently, doing it before your track days isn’t a bad idea. If you just street drive the car, checking it 1-2 times a year is a good option too.
Thanks! We were able to use this same exact method to field-bleed a ZL1 1LE at Road America this past weekend, too. Brought all of the stuff with us just in case!
Hey @FloridaFlyer2 I see you posted a comment but for some reason I can’t find it. Was it deleted. Something about started bleeding your Blackwing maybe?
I did. But then I realized I was a moron and deleted it. Basically, I went to bleed the S/C on my Blackwing today and discovered there is no relay for the pump. Just a standard 15-amp fuse. So I was trying to figure out how to run the pump with the engine off.@@FollowMyLine17
Every LT4 I've done has had small to large amounts of air in the system. There isn't a downside to running the vehicle instead of the jumper. You can avoid spilling when you remove the funnel by stuffing a shop rag in the top of a water bottle and jamming it upside down into the funnel. It's not perfect but it will spill less. I know you guys are up North, but unless your garages are 20 degrees F in the winter, then using distilled water and Redline Water Wetter is the way to go.
Every. Single. One. Yeah, I definitely didn’t use enough shop towels/rags in the video haha. Although my garage is heated, not everyone’s is and we genuinely have seen temps in the -50° range before.
Great question! The adapter from DMS already does that for you! You’ll notice in the video I didn’t use anything to reach down and push the valve in with. All built into the adapter.
Ty for the video, it helped explain alot of missing information. Have you looked into the supercharger bypass valve adjustment? Ive only seen it one other place so idk if its a thing or not. Havent seen it on the forums either, maybe snake oil. Would love to hear your opinion on this, maybe in another video? 8)
The Supercharger bypass valve is an old trick that goes back (for me) to the early 2000’s with the Pontiac Grand Prix. It’s not necessarily snake oil, but it’s not consistent. Some cars may see a bigger benefit than others, based on where the bolts were set when the car was built. Tolerances are also a bit tighter today than they were 20+ years ago too. Maybe I’ll make a TH-cam short on it.
Turns out my original articles from the early 2000’s are still out there and mentioned in a few forums, including the ZZP site. zzperformance.com/blogs/import1/free-mod-boost-bypass-mod
I’ll be doing this on my days off of rest. Thanks for the detailed video! I knew my car was lacking horse power from this.
You’re welcome! Glad the video could be helpful.

Could you do a coolant flush video as well?
I will add it to the list of videos to make!
I see all new and most used ZL1 main coolant tanks filled to the top like yours not the cold line. Why is that?
It’s how they are typically filled from the factory.

Need you do this every week or so because the system has more air. It’s hard to remove all the air in ones .

Was the Preston’s orange? Is it okay to mix colors as long as they’re both dex cool?
Yes, it is orange, and as long as they are Dexcool they can be mixed. The Prestone is also a pre-mixed blend, so no need to add water.
Very helpful video
Glad it could help!
Great video! Thanks for the tutorial.

@@FollowMyLine17 I ordered kit from Dedicated Motorsports this am and mentioned you as the reason why.
@@FloridaFlyer2 awesome! I asked them if they wanted to do some sort of promotion for discounted units but they never responded.

Does the car need to be in Accessory On mode?
No, the car should be off. The relay, or jumper, allows the pump to run with the car off. Accessory or Run is not required.
👍🏻
Do I need anything to push down on the Schrader valve or does the adapter already do that for you?
Great question! The adapter from DMS already does that for you! You’ll notice in the video I didn’t use anything to reach down and push the valve in with. All built into the adapter.
@@FollowMyLine17 Awesome, thank you man
Do u have a link for the jumper wire?
Yes, all the links are in the description. Here it is again:

Thanks what are the terminal connectors type
They are 14awg male spade ends that you have to trim down.
amzn.to/3Sfr3Jo
U should make the relays and sell them, I would buy one from you to make it easier

Heck yah, thank you for the info! I'll check that out
How often does this need to be done if I am just street driving and not tracking the car?
You should check and do it at least every 6 months or so. The system is sealed but it’s impossible to get all of the air out in one shot.
