To replace seals in a hydraulic bottle jack, first, ensure the jack is completely depressurized and disassembled. Remove the cylinder cap using appropriate tools, then extract the piston and old seals carefully, noting their orientation. Clean the cylinder and piston surfaces, then install new seals, making sure they fit snugly and are correctly oriented. Finally, reassemble the jack, refill it with hydraulic fluid, and test for leaks before use.
Open the drain screw that holds the body of the hydraulic jack. This way you can addhydraulic oil to the hydraulic jack.
you can but you'll be buying a new one very shortly afterwards. Use hydraulic fluid. Brake fluid works well also
Yes it does matter. Different hydraulic fluids have different lubrication and thermal properties, they will also react differently to certain rubber seals, potentially causing leaks. You must use the correct fluid specified for the application, with the exception of using a fluid which is approved to mix with or replace the existing fluid you were using. For instance, Mil-H-5606 can be mixed with MIL-H-83282 or MIL-H-87257.
Yes, putting too much fluid in a hydraulic system can lead to several issues, including increased pressure that may cause seals to rupture or hoses to burst. Excess fluid can also lead to foam formation, which diminishes the system's efficiency and can result in erratic operation. Additionally, overfilling may cause fluid to spill, leading to contamination and environmental hazards. Therefore, it's important to follow the manufacturer's guidelines for fluid levels.
The fill port is below the seat on the right hand side.
There should be a screw on the side of the jack--remove and fill until oil runs out of this screw. Make sure that the "ram" is fully retracted into the body of the jack

The jack goes under the quarter window (back side). There should be a metal sleeve under the running board to slide jack into. My recomendation is to buy a small bottle jack or other hydraulic type.

There is a possibility (a danger) that a hydraulic Jack can suddenly slip, or develop a leak and collapse. Once the jack has raised the vehicle, it is put on to jack stands (axle stands) to prevent being trapped underneath the vehicle.
How to add hydraulic jack oil to an hydraulic jack (floor jack or bottle jack).First, don't open the Check Valves!The most common mistake with a floor jack is to open one of the check valves (or their covers) instead of actually finding the fluid reservoir plug. Be sure you have found the filler hole (which can be very tricky to find on an oily old jack -- it's probably a small rubber plug that might even be painted the same color as the rest of your jack, hiding on the housing of the main hydraulic ram, NOT on the base. The screw/bolt heads on the base are the check valves. If you open a check valve, the springs and check balls might come out under pressure, and your jack won't ever work again unless you can find them and put them back in the right places If your jack needs oil, even after a couple of years, it probably also needs new seals. Adding oil might let you use it a while longer, but you should probably replace the seals (or if it's a cheap Chinese/Taiwanese jack, just get a new jack). American- or Japanese-made jacks are probably worth resealing. Please always use jack stands so when the seals really blow out you don't end up crushed.You're probably going to just put jack oil in anyway (or maybe you did replace the seals and now you need to put jack oil in), so here's how to do it:Use Hydraulic Jack Oil (available at auto parts stores). Do not use brake fluid, which will turn the seals into useless cheese.Be sure you have found the oil reservoir hole, not one of the check valves. Do all the following work with the jack rightside up (and don't store the jack upside down or on its side).Clean the plug and jack body around the hole. Any debris in the oil can easily cause damage later.Release the valve/lower the jack (turn the jack handle counterclockwise).Unscrew or pry out the plug as appropriate. Fill the reservoir. A tiny funnel will probably make this a LOT easier). Close the valve and raise the jack slowly enough to not blast oil back out the hole. The reservoir level will go down, which is normal, and you shouldn't add oil now.Slowly lower the jack (again, just don't blast a bunch of oil back out the hole). Air bubbles may come out, causing a few drips of oil to come out too, in which case you should add oil until the reservoir is full, then go back to the previous step until you can lower the jack slowly without a bunch of bubbling.Bleed the air out of the system:Re-plug the filler hole, test out the jack, and you're done, although you should still replace the leaking seals if you didn't already.Remember to always work on hard, level ground, use jack stands, chock the wheels, and set the parking brake.
No, you should not use motor oil in a hydraulic jack. Hydraulic jacks are designed to operate with specific hydraulic fluid that has the necessary properties for proper function, such as viscosity and anti-wear characteristics. Using motor oil can lead to improper operation, damage the jack, and void any warranties. Always refer to the manufacturer's recommendations for the correct fluid type.
Should be a screw at the side of the jack body Make sure piston is in collapsed position and fill with hydraulic jack oil to this level
The hydraulic seals in your power steering will be eaten away by engine oil. Your power steering will start to leek and eventually, it will not work at all.
