  1. Install the reservoir mounting bracket near the power steering pump. We recommend using the inner fender, firewall or radiator core support. Note: If you are using an attached reservoir GM Type II Pump or Saginaw, you can skip ahead to step: 4
    1. Hold the ring up to where you want to mount the reservoir and uses the holes to guide where you need to drill. The maximum angle to mount the reservoir is 30° to avoid accidental spillage. A full reservoir fluid level should be at least 2 inches above the top of the pump.
    2. Note: Before drilling, check to make sure there is room for the hardware to secure the mounting ring and no wiring will be in the way.
    3. Secure the reservoir mounting ring using the (2) 1/4-20 x .75” SHCS Bolts, washers, and lock nuts. mceclip3.png
  2. Assemble the Reservoir
    1. Insert the baffle into the bottom cap on the return side. Tap baffle gently with a hammer a few times until it is secure. You should not be able to remove it with your hands.
    2. Install O-Rings on top and bottom caps. Note: When installing O-Ring on the “Top” cap, make sure the ring is all the way up. Leaving it on the lower groove inside the reservoir will cover the breather hole.

3. Once the reservoir is assembled insert the set screws into the ring, do not put them too far in just yet to avoid scratching of the reservoir tube.

    1. Slide the tube into the ring and get it into the desired position being careful not to block the breather hole on the top. Tighten the set screws once you have found the desired position, doing this before it is in its final position will permanently scar the reservoir.

4.  Now that the reservoir is installed, it is time to assemble the hoses. Start here if you are using an attached reservoir.

    1. The infographic on page 2 of these instructions walks you through how everything will need to be laid out.

5.  Mark your first hose where it will need to be cut. Wrap around the cut line using masking or electrical tape depending on how you will cut it to avoid fraying. Various tools can be used such as a hacksaw, cable shears, or cut off wheel.

    1. Use a vice with soft jaws to hold the hose while you cut it. Regular solid jaws will cause the hose to be squeezed which will cause you problems down the road.
    2. Remove any burrs along the inside of the hose with a razor.
    3. Clean inside of the hose thoroughly with water, air, or a bore brush to remove any debris from the cutting process to avoid damage to the pump. Let hoses dry.

6.  Disassemble the hose ends to slide the outer sockets onto the hose. The threaded end will face towards the cut end of the hose. Tech tip: use a wrench to twist the fitting socket onto the hose if it is tight.

 

7.  Apply assembly lubricant or any petroleum based lubricant to the threads of the socket and elbow.

 

8.  Insert the fitting nipple end into the hose. Remove the tape and attach the end with the socket. The skinny one with the bushing will be used on the high pressure lines while the long threaded one is used on the low pressure line.

    1. To fully tighten use a wrench and the soft jaws on the vice until there is about a .03” gap or the size of about 2 business cards.
    2. Once you know the exact direction the fitting will need to be facing then it can be tightened completely.

9. The CVF Power Steering Line Kit contains various fittings to fit a wide variety of gear boxes and rack and pinions.

 

10.  Once all hoses have been cut to their proper length and assembled with their correct fittings, it is time to route the hoses.

    1. Avoid any moving parts and areas with extreme heat.
    2. Avoid tight bends that can restrict flow or trap air.
    3. Leave some slack in the hoses to account for changes in pressure and movement. Secure hoses anywhere that they may run into moving parts.

Proper bleeding instructions can be found below.

***IMPORTANT*** - It is very important to follow these instructions and procedures entirely.  Failure to do so could result in voiding of warranty and severe damage to the power steering pump.

  • Do not start the engine until the entire bleed process is completed and there are no air bubbles present in the reservoir
  • If using a remote reservoir, the fittings on the bottom of the reservoir should be above the fittings on the power steering pump
  • If using a hydro boost system, follow the bleeding instructions from the manufacturer
  • Use only quality power steering fluid, preferably synthetic or one that is specially formulated for race applications. Do NOT use ATF.
  • Do not reduce the return side of the pump if using a remote reservoir. Combination of line ID and fitting couplings should not be smaller than 5/8

Inspection

Carefully inspect the power steering system plumbing and ensure that all hoses are free and clear from touching any other part of the vehicle, i.e., not resting on the frame rail or gearbox, etc. Also check that all the fittings are mated correctly and tight

 

Bleeding Process

***IMPORTANT*** - Please re-read the section above before beginning the bleeding process

  • Raise the front wheels off the ground and place the vehicle on jack stands
  • Turn the steering wheel all the way to the left
  • Add power steering fluid to the cold fluid level on the dipstick or to ¼” below the thread line on the remote reservoir. Leave the cap off the reservoir
  • With the aid of another person one person watch the fluid level in the reservoir while the other very slowly turns the steering wheel from lock to lock a minimum of 20 times. There is no way to circumvent and speed this up.  Rushing it will only require repeating the process.
    1. If the fluid level has not dropped or there are any air bubbles still present this means that there is still air in the system. A rise in fluid level is also indicative of air trapped in the system.  Continue to cycle back and forth until there are no air bubbles present and fluid level remains constant.  This may take up to 40 or 50 cycles.
  • Once the fluid remains level and there are no air bubbles present, proceed to disabling the vehicle ignition system and crank the engine for 3-4 revolutions. If the fluid level changes or air bubbles become visible repeat Step 4. Continue until there are no changes in fluid level or air bubbles.
  • Install reservoir cap
  • Return the vehicle to the ground and let the car sit at idle for 2-3 minutes while cycling the steering in both directions. At this point you should have smooth operation of the power steering and no noise from the power steering pump. The fluid should be clear and free of any bubbles or foam and the level should remain constant.
