I was working on my IMRC valve and vacuum hoses when I noticed antifreeze dripping from the water pump. $100 and 3-4 hours later, it's still leaking (new pump, serpentine belt, upper and lower hoses, antifreeze, etc).

The pump was a major pain to remove. I pulled the fan, shroud, etc off and had the pump unbolted pretty quick. Then beat on the pump with a hammer and block of wood and pried like crazy. It wasn't moving. I gave up with the block of wood and after beating the pump into a ugly mass of dented metal, it finally came out. It was easy to re-install everything. I didn't forget the o-ring, and put a dab of rtv on it to hold it in place.

It's still leaking. The only thing I can think of is that it is leaking through the bolts. Do the bolts enter a water jacket? Do they need to be sealed with teflon or RTV? Or could it be leaking from somewhere just behind the pump?

I've already replaced the thermostat and all associated hoses. The leak isn't coming from there.

 

what year and engine do you have? if you have the 2.0 or 2.3 you have to seal the bolts. and you should have put sealer on both sides of the gasket before installing on any of the engines.

heres a link for you http://www.autozone.com/autozone/rep...00c15280077d99

 

Thanks for the link cruiser5001,

Since I have a 2001 Ranger, the pump is quite different. It's the first time I've changed a pump where the housing was actually integrated into the block. The pump consists of basically a shaft, pulley mount, and impeller.

Like this:


NOT like this:


Due to the design of the pump, there is no gasket, just an o-ring. I did use RTV on the back side of the o-ring to hold it in place and to fill in any scratches that may have been created in the removal process.

I should have taken pictures as I went along, but I never want to use my camera or phone when my hands are filthy.

This photo should help show how it seals, with the o-ring.

 

I'm about to do this tonight/tomorrow, what were your findings with the bolts and the leak you had?

I want to avoid any possible issues..etc.

Thanks,

My truck: 2002 Ranger XCab, 2.3L DOHC (Duratec) 2wd / 5-speed M5OD tranny, 105k miles.

Just started this train wreck this morning. Ran into the seized-pump problem also. Here's the pictures I've taken so far. Need suggestions on how to get the pump out.

I read the remarks about the hammer & wood trick, but it concerns me that the housing might have gotten warped a little from the beating. As expected, none of the shops around here (Killeen, TX) will tell me anything on the phone except "bring it in and we'll look at it" $$$$ is where that goes.

Here's the pictures I've taken so far in my attempt.

 

The beating on the pump didn't help for me. What helped the most was taking a flat blade screw driver in between the one side and slightly pry the edge out at which point I grabbed the pump by both hands and started wiggling it back and forth for almost 3-5 minutes before I could get it out. Beating it didn't move it at all so I did this and it worked well... Just be careful NOT to nick the metal or bend anything that shouldn't be bend.. IE: Put the screw driver or really anything flat in there and just slight pull it so you can get a wiggle room out of it in a way...

Pics aren't loading btw.

Just uploaded the pictures. Now gotta get them onto this page. Still learning how to do these forum pages. Not that knowledgeable with them yet.

 

First step is getting to the pump. Gotta move everything out of the way.

 

Pump is on the drivers side under the power steering pump. 10mm pulley bolts. I used the wrench & ratchet trick to get them off. Broke the bolts loose with the serpentine belt still on for a little extra stick.

 

Once the bolts were loosened, 3/8 breaker bar on the tensioner to take the serpentine belt off. Tensioner is on the passenger side, halfway down.

 

This is the pulley once its off.

 

This is where the fun begins. Three 8mm bolts. But they don't hold the pump in as much as the 100k miles worth of heat-cycling seizes the pump in place. Its not a pump that sits on the surface of the housing the way the old pumps on Windsor engines did. This one is a male-pump-into-female-housing fit. Seats in about 1/2"

 

Here's a picture of the pump straight out of the box. Notice how far down in this pump will seat when its all the way on.

 

There is no gasket, just this o-ring to seal the pump.

 

This is as far as I gotten. Truck is still in pieces in the driveway. I took a chisel and tried to drive it down between the pump and the housing, but couldn't get a solid enough swing to do any good. Time for round 2.

Wish me luck. More pictures to follow as I get this poorject completed (no that's not a misspelling, I'm broke, wallet is flatter than an anorexic chick's *****).

 

After breaking off a wing from the pump, I ended up realizing I'd have to move my power steering pump and reservoir out of the way to be able to get at the water pump better.

 

 

After I got the PS pump out of the way, I had a lot more space to work with. I used the chisel to move the pump out a little and then finished it off with a big screwdriver and a super-sized tire iron.

 

I cleaned up the area and RTV'ed my bolts and put the new pump in, remounted the PS pump and reservoir, but the air tube back on, filled up with water to see if it'd leak, got it sitting out in the driveway till the RTV cures.

If you can get to this point, reassembly is reverse order.

Next up is the vacuum leak. I freaking hate vacuum leaks.

Just a picture of the new pump and the old pump.

 

Here's a picture of the serpentine belt pattern in case you don't have the sticker anymore and are forgetful like me.
