XFR Water pump change
#21
Bigg Will...dude..I think I broke the little nipple that goes into the water pump on the front end. The damm thing is a PITA to take off and I may have gotten impatient with it...anyhoo. Is there a replacement nipple for this thing? I am losing small amounts of fluid.

damit!!!!i new it was going to be something like that....just my luck...I hate it when I validate your sig...lol.....for the sake of this not happening again....I am supposed to push on the little brass ring and that should release the hose correct? Freaking manuals...all they give you is one picture, no words, and a vague arrow pointing at something...lol

With the plastic bleeder screw (It's in the heater line by the fuse box) off, and the heater turned on, I fill the engine through the upper radiator hose ( from the disconnected radiator end) first, then I connect that same hose to the radiator and fill it (from the disconnected engine side). I now connect the upper radiator hose and then fill through the coolant fill tank until coolant it comes out of the heater hose bleed. Close up everything and idle the car until the upper hose gets hot, shut it down and wait about an hour. Check your coolant level if you need to add coolant do so and repeat, don't drive the car until you don't have to add coolant and your heater blows hot. after you do drive the car with the car, keep an eye on the coolant level for a few days, it shouldn't need much if any.

The water pump bleed off.
Now the way I did the magic of getting the tube inserted and pump mounted with no leaks is, I lined up the pump, and hold it in place just before the seal seated, I then screwed in it's bolts just enough to let me shove the water pump straight back in place, seating the tubes seal. I then tightened the bolts by hand snug until I could torque them in a cross pattern.
When ever possible I replaced the torx bolts with flange bolts. Flange bolts are way more forgiving if you get on them wrong, and easier to get on in tight spots, like the whole XF engine bay..lol
And back to that cross over pipe, it has this seal insert inside of it. If the dual seal leaks it will run down into the V, and look like the plastic tube is leaking, so just go ahead and replace it. The seals were $8 ea. the whole part with the seals $15?
Mine looked like this, I replace the complete seal but it was too narrow, and the correct thickness seal was missing a section. I wasted a gallon of antifreeze chasing this..lol
Once all is back together and filled with coolant pressure test again. Mine held 16lbs. for 3 hours

Water pump bleed off.
The AJ133 water pump is not a hard beast to change, but you do need to remove EVERYTHING that will obstruct you from pulling it straight on or off like idler pulleys and move hoses a least out of the way.
In addition but not absolutely necessary I would remove the cross over pipe that bolts to the SC snout and throttle body beneath it, as this will give you more sight behind the pump and on the infamous PLASTIC TUBE!
BE SURE AND PUT THE NEW PLASTIC TUBE IN THE SAME WAY THE OLD ONE CAME OUT!
The oil cooler that is fed by the water pumps plastic tube (lower center). That pipe sticking up is what the cross over pipe joins when the SC is installed, more on that later.
New tube in. Some general tips, the pipe has two seals that are the same, one seal goes on the nipple on the oil cooler into the tube, and the other seal goes from the tubes nipple into the water pump, you want to lube the nipple the seals go onto, and the hole the nipple and seals go into, but NOT the seal itself. And DO NOT use a silicone based lubricant. Install the seal on the tubes nipple as shown.

Thank you for replying to my other comment @Bigg Will and for directing me to this post.
After fiddling around, i found the source of my leak but can't seem to find what this part is called or what the part number is.
The part that's leaking is the plastic unit outlined in red in picture 1.jpg (attached below). While I'm in there, I'm planning to changing out the part outlined in red in picture 2.jpg.
If you guys have the part number, for those 2, that would be very helpful!
