fluid extractors: griot's or mityvac or other

Hey guys, I'm thinking about getting one of these if they work. Maybe use for axle and transmission, and p/s fluid. I have a boat also, so if that works for the oil, that would save money from the boat mechanic.

Thoughts?

I bought the Griot's version for changing the transmission fluid on my BMW. Worked great. I've used a lot of their products and have never been disappointed.

 

The exchanger/extractor from mighty vac will not push heavy fluids; gear oil and such. Works great for lower viscosity oils.

 

Thanks for the replies. I was hoping to get one that does everything. Next year plan on doing axle fluid, and was hoping one of these worksites

I haven't found a pump like that to push heavy fluids. There is an inline air ratchet operated pump with a tube coming out of either end to pump the heavier stuff.

 

I've used the Griots extractor for quite some time. It works great for oil, auto transmission, brake; power steering fluid.

If you are trying to remove gear oil from a differential that has no drain/refill plug, use a hand pump and be sure to first warm up the vehicle so the gear oil has thinned out some.

I know a lot of people like to fill differentials from underneath the vehicle with a preloaded pump. I prefer to do it topside. Buy some large heater hose - maybe 6' to 8' in length - depends on your situation. Install a plastic tube in one end and lock down with hose clamp. Plastic tube is inserted into diff. refill hole. Snake hose up and over top of tire. Put a funnel in the other end of hose and slowly pour in your gear oil. Have a clean pan under diff. just in case. Been doing it this way for years. Works great. Gravity does the work.

 

Thanks lugnut, so, your saying use a hose on top to the drain plug? I've used one of those pumps on a quart of gear oil on my old suburban, and got that crap all over.. mess.. thanks for the tip.

Again - a long stretch of heater hose with a plastic tube in one end fastened down with a hose clamp. That is placed into the refill port on the diff. Snake the hose up over one of the tires. Connect a funnel to the other end and slowly pour in gear oil. The oil will move slowly - but it will move. You can take whatever measures to like to ensure the hose end connected to the diff. does not slip out. A catch pan underneath the diff. would not be a bad idea in case it does.

 

Lugnut, that's a good idea. Gonna take your advice
. Thanks again, Chris
