- Replacing A Hydroboost Unit - EricTheCarGuy

This is actually the first one of these that I replaced, it's a little more complicated than a regular vacuum booster but not by much. I looked up the procedure for installing the system and it said to crank the engine without starting it, if I were to do it again I'm not sure I would bother with this because the fluid didn't seem to flow until I revved the engine past 2500, once I did this things started to work normally.

A couple of tips from a long-time mechanic. When youre doing anything under the dash? Take 10 minutes to remove the seat- you will create SO much more room for yourself it changes everything. Second- always have some kind of penetrating fluid on hand, most guys like PB Blaster or Deep Creep- my preferred brand is Aerokroil- amazing stuff. Be very generous about wetting down any exposed threads before unbolting everything- things come apart twice as fast when the threads have some lube and you'll be able to undo many bolts by hand that otherwise would have required the socket wrench. Stay safe out there-
Had to replace the hydroboost on my 2001 Safari van. After watching this video it was quite clear how to accomplish replacing it. Thanks for posting this. Local shop wanted $700+ to do the job. I did it for the cost of the unit thanks to you!
Underneath a dash, fighting a c-clip, in the cold, AND holding a camera. You are the man Eric!
@sbakar The important thing is to stay positive, it's only a machine. And yes it was pretty late at night when I finished, that was a long day.
im doing mine today 2003 astro, I do all my own work, and know exactly how hard anything under the hood is to replace, great video, keep up the good work
@outlawsonic I'm happy to help. Thanks for the great comment.
Thanks for the video! I'm converting to a hydroboost because my aggressive cam wasn't giving me too much vacuum. This was the best info on hydroboosts I could find! Great work!
@AngryGunNerd Actually the job wasn't as bad as some of the things I've had to do to these vans. I think timing belts are easy for the most part, depends on how much clearance they give you though. Thanks for your comment.
@IIGrayfoxII Labor was only 2 hours but the part was pricy. If I'm honest compared to some of the stuff I've had to do on those vans this was fairly easy. Thanks for your comment.
@xylenol15 Actually they use the same engines they just have a different body configuration, they can be difficult to work on as a result of these configurations as you point out however. Thanks for the comment.
@Ryskimus Well it's been very well received so I'm happy for that. I love making these videos even if some present more of a challenge than others.
That was 11 years ago, but I'm glad I watched it, as I plan to put a system like this in a 63 C10 I'm building. Thank you Eric
@MrGW24 The only reason I did it that way was to show the use of hand tools, if I were going to do it I would have just used my impact and been done for all 4 fasteners. You make a great suggestion though, thanks for your input.
@beefystik Thanks for the comment. I can honestly say that when I got out of school it was only the beginning of what I was to learn, school is a great start but the learning really begins when you start working in the field. Best of luck to you and thanks again for the comment.
Eric TCG, thank you for the video and especially for showing so much detail. I'm currently on a problem with the brakes dragging on my 2003 Astro. After 10 miles they seize up and overheat. I needed to see the mounts of the master cylinder and the hydroboost connection to the brake pedal before taking the wrenches to anything. Your video covers it very nicely. Your work is greatly appreciated.
Rather old video now, but still very valid. I replaced a Hydroboost unit yesterday on a Savana 2500. This video shows a slightly different unit and orientation to the engine bay, but proved very handy in assessing the repair prior to taking it on.
Great video - appreciate you taking the time, i got a 1995 Astro and Hydroboost just went out and need to change it. Thanks for putting this together and getting me in the right frame of mind and start this repair.
@binnsh I've used those, I think they are referred to as "wobble extensions" depending on who made the tool.
@JohnnyDesaint You may still have air in the system, the air in this van didn't purge till I revved the engine up to almost 3K in order to get the brakes and power steering to work. In your case however if that does not work I might be looking to the lines to see if there is a restriction somewhere as it will result in the sam problem and possibly cause your performance issue. Lastly make sure you used the correct fluid, in the case of this van it had to be power steering fluid.
@HD8Track I've been using Diamond Grip for years, I'm also kind of cheep so I try very hard not to tear them if I can help it.
