Anyone using these on a honda car engine? I was thinking to maybe try and use it to replace lots of fluids on the car such as the tranny, oil, antifreeze. Just clean out the pump if I use it on different fluids.

thanks

Vacuum pumps are designed to remove air/gas not liquids. 94

Ummmm really? I use a vacuum pump to bleed my brakes. Isn't brake fluid a liquid?

To the OP, it would be better to change your transmission/oil/antifreeze fluids by using their respective drain plugs. That way, more of the old fluid will be able to drain, not to mention it would make life easier.

Did not say it would not work, you can use a 5lb ball-peen hammer to drive nails but it is not the correct tool for the job. 94

Drain your coolant and tranny through the drain plugs, hmmm, what percentage comes out this way, hmmm.

The semi new way for professionals to drain a cooling system is by vacuum, not the way the OP wants to do it by with a type of vacuum machine. How do quicklube places remove and replace tranny fluid, in my area they suck some out, replace some while the engine is running, suck some more out replace some, etc. If they go direct to the two cooler lines with the machine, costs more, they flush most of the tranny fluid this way.

Do not think that you will use that pump in the future to draw down an AC System though, dont do it. You will also need to change your vacuum pump oil more often also, so be aware of that additional cost. It must be extremely clean and crossover does occur.

Just want to make sure we're talking about the same thing here. When someone mentions vacuum pump I imagine this:

Now according to Mityvac's website, it can be used for fluid transfer/evacuation, not just for air or gas.

And Imagine one of these... http://www.redhillsupply.com/ROB15234.htm 94

i have one i use on a daily basis but for only resivors or their respective bleeders, if you use it for oil/trans fluid you are going to just get a sample not all of it, power steering and brake flushes makes them a breeze though.

edit: i also have a cooling system vacuum bleeder as well draws ~25hg of vacuum on the system and it sucks the coolant back in 99.9% of the time with out any air bubble at all. said tool in question i have is from matco hate navigating their site so i lack a picture of it
