Thoughts on AMS findings regarding divorcing coolant

You guys can also review the video ECS put up when they pullied my car as it covers the whole bumper removal… I also have the CPS install pdf’s from APR if anyone needs them but I think AMS said they would have some out within a day so I’m sure they’ll cover everything as they seem on top of stuff…

Oh and you can always rent that tool out… My pulley tool has been rented to a lot of people so far… lol Heck there is a guy on here getting it soon for the 2nd time ;D… lol

Finally, love how Swank is telling them how to run their business from a pricing and margins standpoint… lol

LOL Ken you beat me to the Swank post… He’s such a treat isn’t he…

Saki, when did he post a picture of his car? I think you mentioned that somewhere… I still don’t think he owns one…

He posted a pic of his AK for David@EC to prove he owned one. But refused to give him the order #. Those guys really went at it big time a while ago about the sway bar bullshit. Guessing he’s had a serious case of the “warranty denied due to mods”…maybe because of online pics or social media, who knows, but he’s a super paranoid guy.

im curious if AMS is using the PWM signal off the stock pump of if they are just using the main trigger. The pump they are using is a PWM pump.

How can I find out for you? Tell me what to look for.

Well they are using 2 wires off the factory pump, the yellow/red and the brown wire. depending how they wired the relay, it seems odd that they ran 2 wires to the stock pump if only a “trigger” wire is needed.

I guess i just need to lookup what the yellow/red wire goes to. im sure brown is just ground.

I will be an early adopter as well. Cant wait to get it on. Shipping says it should be here on friday! Would love to tackle the install myself but I don’t think I will have that kind of time until thanksgiving :frowning: Having a local shop put it on sometime next week. I’ll be making a review to get some $$ back so I’ll share that on AZ and here as well

Here is a video from my post in AZ so you can hear the pump:

As requested, couple view points, hood open, hood closed, inside the car with windows cracked, from wheel at pump side, from about ten feet away, etc.

Id say the video is fairly accurate sound wise, maybe slightly louder (10-15%) because of the garage keeping the sound in one place and volume levels on your viewing device.

Hope this helps, cheers

And yes coolant cap is off, system burped so I was getting the fluid to the proper level.

I’ll be honest, that is much louder than the AWE pump, quite a bit actually, you don’t even hear the AWE pump other than the fluid circulating.

Then again, how often do you listen to a pump with no other noise in an isolated garage lol.

People that complain about the noise I think are a bit, um, slow?

When the car is on, you WILL NOT hear any pump.

Air raid!

Ps video says fuel pump?

Think I’m going to try and tackle this either this Saturday if everything comes in tomorrow, or next Friday/Saturday.

I was going through the install instructions riddle and it looked like a lot of work. How mechanically inclined would you say you are?

It was late at night I was two gins in, I was telling my self it sounds like a fuel pump priming so that’s probably what I wrote

I’m mechanically inclined to a degree but didn’t do the install. AMS is in my backyard, they handled it to write the guide and make sure b8.5 firmament was 100%.

In the office so I hope this youtube link works… Here is the APR CPS running… I posted this quite some time ago but figured it was worth comparing to db’s video…

https://m.youtube.com/watch?v=eSZVDdwrj5M

Also, I just compared db’s average IAT’s for his 6 passes he logged at his last visit to the strip when temps were about 75F humidity in the mid 50’s and BP in the mid 29.xx range vs some testing I did on August 10th at the dragstrip when it was 75F with humidity in the low 70’s and BP in the low 30.xx range…

His average IAT over 6 runs was 67.24 My average over 4 runs was 62.72 Lots of other variables to consider like wait time and such but figured I’d mention it…

If you are asking me, I would say slightly above average on cars, and maybe more than that on other things… I have done lots of suspension, brakes, now the supercharger pulley, etc. I feel pretty comfortable doing anything up to tearing apart an engine/trans/diff, but I am not a mechanic by any means. I haven’t done something specifically like this, but it seems pretty strait forward except bleeding the system, and only because it is a little different than most coolant systems with the S/C. I am pulling the engine on my B5 and replacing turbos right now, and I feel fairly confident doing that.

I worked in the semiconductor industry for the past 13 years doing a lot of hands-on work with robotics and automation equipment, and would say I was way above average there (I was “the” technical expert at our company, and literally troubleshoot and dealt with every major problem we had for the past 10 years).

I would say if you are comfortable with the instructions, and all the tools required, it seems like a pretty easy install. Maybe a 6/10 (on the same scale mentioned earlier where removing the bumper was 3/10). At the same time, I would not be opposed to having someone do it if I didn’t have a lot of time. I don’t have a job, so I have a lot of spare to time to slowing work through something like this, and other cars I can drive, etc.

@ron, I also had a dirty filter in and the big screen, wonder if that would make the difference?

As far as bleeding the system, i would look into getting an Airlift. They make 2 models, the 550500 which runs about $85 on amazon, and the 550000 which is $123. ECS started selling the schwaben one 003466SCH01 for $75.

I have the 550000 and i have to say its one of the best investments in tools ive made.

What it does is suck out all the air in the coolant system, then you place the tube into a bucket of coolant and flip the lever, it then sucks all the coolant back into the car to replace the air. This completely bleeds out the system as all the air pockets are replaced with fluid. It will take you about 1 minute to completely fill up the cooling system.

Thanks. Good to know. I’ll probably invest in one since I really need it for the B5 too…

What is the big difference between the two airlift models, and what type of attachment does it use from the air compressor?

I may just go with the Schwaben. I need to order some coolant anyway. Is the standard 1 gallon size enough (3.78 liters)? I was planning on a 50/50 mix of the Audi G13 coolant and water. That would give me 2 gallons total, but I know AMS said their tank added a gallon of capacity…
