Can a trans cooler work on a Hydro Booster?
The fluid gets hot, cooks the seals and can cause damage to the hydro booster and steering parts. Just any small trans cooler will work fine as a PS cooler– just connect it to the return line, before the fluid is returned to the PS pump. All of these trucks should have came with a power steering fluid cooler. .
How does the Hydroboost work on a diesel?
Since diesel’s do not create vacuum, the assistance method changed from vacuum (older diesels had a vacuum pump) to pressurized fluid. This might help to understand how the hydroboost is tied to the brakes and steering at the same time. The lines and brake fluid inside the master cylinder are completely separate from the hydrobooster system.
How is a Hydro Booster similar to a vacuum booster?
The hydro-booster is the same as a vacuum booster only runs off of fluid power. The power steering pump supplies the pressurized fluid to both the steering and braking components. When you press the brakes, pressure is used to increase the pressure of the brake fluid making it easier to stop the vehicle.
Do you need a return hose for a Hydroboost?
It is in a good air flow place, and comes with everything you need (cooler, hoses, clamps, mounting bolts) except a 3/8 inch connector, to connect the cooler hose to the return hose. You also need two large fender washers- because the holes in the bumper are large size.
What makes a Duramax Hydroboost hard to fix?
The input shaft seals are what make it difficult, as they have to be slid on over the end of the pushrod. The Duramax Hydroboost uses what Bendix calls a ‘non-serviceable’ pedal pushrod, and some of the Bendix manuals state that if you feel the need to replace those seals, just buy a new unit.
How do you remove the Hydroboost from a car?
Once that clip is off, you can simultaneously slide the electrical connector and the hydroboost rod off of the brake pedal. Now from the engine bay, you can pull the hydroboost unit away from the firewall. You’ll have to push the brake master cylinder out of the way.

How to fix a Hydroboost leak in a Chevy?
Now from the engine bay, you can pull the hydroboost unit away from the firewall. You’ll have to push the brake master cylinder out of the way. I pulled up on it slightly and pushed it towards the fuse box, while pushing the hydroboost towards the engine and pulling away from the firewall.
