My Explorer is bleeding!

[mental_help]

There is this vacuum hose that runs into the throttle body it is plastic but the end is rubber and it is very spongy but it still sticks on there some what.
So I was checking on it to day and pulled it off and a small amount of red liquid dripped out. Also there is a small amount on the throttle body butterfly. So I was wondering if this is normal or bad. Here are some pics…

only red underhood fluid is tranny (maybe PS fluid) and it dosent sound like it should be there

But im curious, do you just go tearing around you explorer poking/pulling at things?

If you have an automatic transmission, occasionally the vacuum modulator goes bad and fluid is sucked up into the engine vacuum system. The primary symptom though is blowing off the vacuum hoses at the vacuum manifold and you didn't mention that.

Do a search on vacuum modulator replacement for further info.

I do on things that look like they need to be replaced.

What do you mean?

I think that he's referring to you hitting your battery with a hammer! Seriously though, if you want to check to see if the vacuum modulator is where the red fluid is coming from, it's located on the passenger side of the trannsmission, behind the heat shield if you have one. There is a vacuum line attached to the side of it, and if tranny fluid leaks out of it when you pull it off, then you have a bad modulator. Also, if your auto parts store can't find a listing for the modulator valve, tell them you need one for an '88 Bronco II, it's the same one, and they usually list that one. Good luck, and don't forget, a hammer isn't always the best tool for the job! jk

Well I found out where the "blood" was coming from I was checking the vacuum router and pulled off each hose and turned it upside down on my hand to see if there was any liquid in it but then on the last hose (pictured below) a bunch of red liquid poured out into the palm of my hand then it stopped poring out. Now I just need to know what to do any suggestions on what to do?

As mentioned, replace the tranny vacuum modulator. Do a search of this site for a procedure.

It's easier to remove the passenger seat and center console, then pull back the carpet to remove the access plate. It's almost impossible to remove and replace this part from under the truck.

Just make sure that you don't lose the "pin" that's in the modulator valve when you pull it out, they are hard to come by for some reason.
(and don't hit this one with a hammer!!!) jk

 

[mental_help]

does any body have any pics of this done?

 

[Gadget X]

I'll see if I can take some pictures in the morning. Right now it's too dark.

Try search on replace vacuum modulator.

You want Howard's posts showing drawing and link to instructions.

Someone also has posted pics of the actual operation and a caution about losing a pin. I don't have an automatic so it's not bookmarked. [Someone else just posted a pic of the modulator]
