hydro boost install question...HELP!

[mauibronco]

howzit guys!

the guy who is installing my hydro boost said that the last one he did on a bronco (which had the stock p/s pump) put out so much fluid from the 'low pressure return to the ps reservoir' that it blew the cap off the ps pump and fluid went everywhere....he said they had to rig up and external reservoir and mount it up high to avoid this issue....have you guys had this same issue?? I have a saginaw pump and im hoping to not have to mount some crappy looking external reservoir.. is this a common issue with the hydro boost because if so i would think the vendor would have mentioned it and that they would sell something to deal with this??

mahalo for any feedback!

Explain to me how a low pressure line blows the dipstick out of a stock pump.

The only reason the fluid would puke out is if it was overfilled or if there was air in the system due to not being bled correctly.

 

[mauibronco]

im not sure...im a mechanical dummy, thats why im having a mechanic install the hydro boost....im just going off what he told me..

I'm going with what Justino said. If you're running a saginaw, then you basically have the same system as I have. Yes, mine puked up some fluid as I bled the system lock to lock, but that happens if you get too much fluid in there prior to getting most of the air out. There is absolutely no need for an external reservoir when running a saginaw. Here's some early shots of my setup for reference. You can clearly see I only have the boost unit and the saginaw pump. Good luck! Cheers, B2

 

[mauibronco]

okay bsquared! thats good to know....illl pass on the info to my mechanic...thank you so much for the pics!!

 

[Cortez]

I run the same setup and with a sag pump, no issues...and I don’t have a dual return pump reservoir only a t to join the two returns befor the reservoir.

 

[mauibronco]

thanks cortez!! im thinking he will use that t as well!

It is not even possible for any appreciable flow volume to come out of the return line from the hboost unit...you might need to look for another mechanic.

It's not uncommon for large return surges to overflow the reservoir due the escape of compressed trapped air from the steering box.....with or without hboost.

Can you Identify the 3 hoses in the picture.
I'd think red is High pressure & Green is bypass .Blue is returne.
....................
But I was just wondering . IN all my years on here I've never heard any need to add
an extra reservoir.

 

[Crush]

Green = pressure from pump to hb
red = pressure from hb to steer box
red = return from hb to pump
blue = return from steer box to pump via a cooler

you must have a dual return steering pump or a t fitting in the return line. If you use the t fitting the straight through side of the t must be in the power steering line so the hb return t's into the side of the steering line. If you dont do this it will usually cause problems of the steering not wanting to steer very easily

hope this helps

I'm late to the party here, but I'll add that I recently put ram assist on and in the process had to drain the steering box. So it had to be bled. Even after bleeding it, it would hemorrhage fluid if I cranked on the wheel too quick. All I can assume is that it was still bleeding air, meaning the reservoir was overfilled...even tho it was a couple inches below the cap. (Explorer setup, BTW, but the idea still applies.)

 

[Apogee]

Hydroboost uses all of maybe 2-3 tablespoons worth of fluid when you apply the brakes...it's almost nothing and it certainly doesn't change how the rest of the system works. While I am a fan of remote reservoirs with built-in filters for HB applications, that's only because it makes bleeding easier and protects the HB power piston and seals from shrapnel from the pump and/or steering gear, thus extending its service life.

I'd be looking for a new mechanic...or more likely do it myself.

 

[ehumaui]

I run the same

[Hozr]

Only way I see it blowing the cap off is someone ran the pressure line that should go from the Hydroboost to steering as a return line to the pump.

 

[gr8scott]

Green = pressure from pump to hb
red = pressure from hb to steer box
red = return from hb to pump
blue = return from steer box to pump via a cooler

Sorry Crush, but that's wrong.

Red= high pressure from pump to HB
Red= high pressure from HB to steering gear
Green=bypass from HB to pump
Blue= Low pressure return from steering gear to pump via a cooler

At least that's how mine is configured and it works perfectly.

 

[Apogee]

Red= High-pressure from pump to HB
Red= High-pressure from HB to steering gear
Green=Low-pressure return from HB to pump
Blue= Low-pressure return from steering gear to pump via a cooler

This is correct with the term "bypass" changed to "low-pressure return". If you run a tee fitting on the return lines instead of a dual return pump/reservoir, make sure the straight through flow path is inline with the return from the steering gear, since that's where 99.9% of the fluid will flow.

 

[Rustytruck]

Saginaw pump with t fitting too. I did have a spill when I first set up the system because the dummy in me put in a power steering cooler in front of the radiator with the cooling lines under the cooler and mounted higher than the pump. After filling the system and turning off the engine the filled cooler drained down the line and overflowed the pump.

Once I found my mistake and remounted the cooler so it holds oil on shut down all was well.

 

[mauibronco]

mahalo crush! mahalo everyone for chiming in....

 

[Pa PITT]

JUST FOR THIS THREAD .. Isn't the fitting to the front on the gear box always HIGH PRESSURE .
i THINK THAT'S WHAT I was told when I did my P/S SWAP.
