Oil Extraction Pumps

[PistolPete]

I’m now in the position where I’ve got two cars with oil filters in the top of the engine. I saw a picture of one the other day and thought that would be a good tool to have, not to mention I’m starting to feel when I’ve been laid on a cold floor now!!

Do they have any negatives?

Can anyone recommend one?

I've used one for a while now - wouldn't go back to do it the old way crawling round under the car on a wet winter's day. I've heard people say that they don't get rid of all the oil but I've not had that problem. I change my oil every 5k and since this makes the job so quick and easy I'm all in favour of more frequent oil changes.

This is the one I have www.amazon.co.uk/Sealey-Manual-Vacuum-Fluid-Extractor/dp/B000RA16CO/ref=sr_1_5?ie=UTF8&qid=1515596551&sr=8-5&keywords=oil+extractor+pump

Not a bad price on Amazon at the moment. I got mine from a boatyard as it was cheaper than from an auto place. They are widely used for marine engines as access is limited.

The two sections of the pipe can be a bit of a pain to join if they are cold. Don't overpump them, just enough to keep the oil flowing. The usual trick is to run the engine to warm the oil up as cold oil is harder to suck out.

They are also very neat when it comes to pouring the old oil into the container - no spillages unless you're really clumsy.

I've done oil changes without even changing into the overalls, they are that quick, clean and simple to use.

How long are the hoses on the one you have? I’ve got a discovery 3 so it’s quite high off the ground.

I’ve read horror stories of the extraction tube becoming separated from the put and sinking down the dipstick hole, is this possible with your kit?

I bought a cheap electric oil extraction pump from ebay to change the dual pump fluid in the diff of my CRV.
It did the job easily & I was so impressed I decided to change the engine oil using it. Again it worked flawlessly.
I'm not too worried about the small amount of oil left behind as I change the oil every 6 to 9 months anyway.

The pipes that push onto the pump of the one I bought are a good 2 or 3 metres each.
Only down side is you have to have a container to pump the oil into but the last oil change was the cleanest oil change I have ever done.

Can these pumps insert oil too? Like a diff for example? I bought a sealed one years ago and it was diabolical

I used mine to get as much of the dual pump (rear diff) fluid out of the crv and used it to pump the new fluid in.

There is a fill and drain plug on the diff but not a lot of clearance around to use a bottle etc to fill the diff so I bought it with the intention of just using to put the fluid in the diff.
I managed to get more of the fluid out by using the pump to remove the fluid too as the drain plug isn't on the bottom of the casing so it was still holding a little of the old fluid when the drain plug was removed. (I pumped the fluid out of the fill plug to start with).

I'm not too sure how durable its going to be as I have only done the dual pump fluid and a oil change with it so far but it wasn't expensive and didn't seem to be getting hot or making any strange noises.
Time will tell but if/when it breaks I will be getting another that's for sure.

The hoses come in two sections - and you get three! There is the one that connects to the pump body then two alternative extensions to stick down the dipstick tube, one thinner than the other. Whichever two you use together gives you about 3 metres. For a Disco you might need to raise the pump slightly, just put an upside down bucket under it - it'll work fine.

There is no way the tube can sink into the dipstick tube - the end has a thick connector piece that simply wouldn't fit. Plus, once you've inserted the tube it hits the bottom of the sump so you can't push it in more than that. For a Disco you'd be using the thicker tube anyway and that doesn't bend once it hits the bottom of the sump. The thin one might - our daughter's Aygo needs the thin one and you can push that in a bit too far but it can't disappear into the sump.

No - they work on suction generated in the extractor body.

I bought a Laser hand pump one, it was rubbish so I made my own pneumatic one.

Its a garden spray bottle acting as a vacuum tank and a vacuum generator from work (just a venturi really), an air switch and some pipes.

It works very well indeed, you connect to your compressor, flick the switch and the oil ends up in the bottle.

I always warm up engine oil before changing, its quicker that way.

What happens if you cross the streams?
