How to use a fluid transfer pump

Fluid transfer pumps are a very useful part of any wrench’s toolbox. They are designed to suck automotive fluids out of their bottles and transfer them to their new intended home via long hoses, especially when working in tight spaces, such as replacing differential oil, automatic transmission fluid, or gear oil. manual transmission. They are also quite useful if you need to drain fluid from a component before replacing it, such as a brake or power steering fluid reservoir.

These are also simple machines. You don’t need a PhD. to operate them, but you need to know a few things before you start. So let’s dive in and get to a safe workplace “transfer.”

Here’s how to use a fluid transfer pump

Put on your favorite montage music and turn up the volume.

1. Prepare your intended goal

Loosen the cap and, if necessary, drain the fluids from the automotive component you are working on. If it’s a transmission, remove the fill plug. prior to the drain plug just in case the fill plug can not be remote. The same goes for a differential, although many differentials use just a plug, hence the use of the fluid transfer pump.

2. Get ready to pump

Take the bottle from which you will draw the fluids and make sure that it is stable/firm/does not tip over. If you’re removing fluids from an automotive component and pumping them into a container, make sure it doesn’t get spilled in the process.

3. Position the latch

If you are draining liquids or filling something until the liquids drip, have a drain pan underneath ready to catch them. Let’s all do our part by not introducing toxic chemicals into places where they don’t belong.

3. pump

Remove the pump from its packaging if you have not already done so, use the proper size hoses it came with, connect them and make sure they are in the correct orientation. In the case of the illustrated model, the “IN” end means where the fluids come from and “OUT” means where they are going.

Then simply extract them and pump them to their new designated home. Be sure to follow what the capacities of your vehicle are as designated by the manufacturer, as well as what the filling procedure is. Some cars require filling to the point of spilling fluid, others have very specific capacities.

If you are using the pump to first drain the component and after top off, like removing oil from a diff that doesn’t have a drain plug, it’s a good idea to run some clean oil through the pump first to flush out all the old stuff, and be sure to follow the published capacity exactly the maker is while recharging. However, it’s often a “fill ’til it drips” type of scenario.

quick tips

  • Be careful with fluid spills under the hood of your car, as things like brake fluid can eat away at painted surfaces.
  • Be very careful when using a fluid transfer pump to siphon gasoline and make sure it goes into a suitable and safe container.
  • Be sure to properly dispose of all automotive fluids
  • Keep all fluids away from any source of open flame or hot exhaust.
  • It’s a good idea to cap the lines of a fluid transfer pump after use so they don’t get dirty during storage.
