Anybody have or knows of a link for a diagram of the coolant lines around the heater core, 2001 V10 4X4?

I have a leak that just started somewhere between the passenger side manifold and the firewall, I can't see exactly where it's coming from, but as soon as it builds pressure it sprays the manifold which causes it to steam. It drips down onto the rear of the front passenger side spring perch, so isolating it when its leaking is tough.

 

This is the best I have, Steve. Hope it is enough. From the 2005 Service manual for v10

Thanks Bion!

I think that might be what I was looking for, I'll check later when I get home!

Just hope the rain stops, it's really coming down up here!

 

Raining like hell here in South Jersey too. Cold, pain giving rain.

I have had a LOT of broken bones and I'm eating Ibuprofen like candy.

Sore head to foot on days like this.

 

Sorry to hear, hope it clears out fast!

 

Found the leak from the diagram you provided, if you look at the second page top left drawing, that hose connects to a metal tube on the back side of the motor and loops back under the intake manifold going to the water pump. The leak is the metal tube on backside of the motor before it bends back forward.

 

Thankfully you found it.

now to find the dang part, eh?

 

I found a post here in the Expedition/Navigator forum.....https://www.ford-trucks.com/forums/7...ml#post6359125

 

Ain't this place grand?

FTE. the place to fix your truck!!

 

So it is the metal tube? Much better than heater core.

 

Here are the parts I ordered today to hopefully fix this issue...

(1) #4C3Z-18663-CA Heater Tube - Long tube that goes from the other end of the hose on page 2 (top left picture) to the water pump.

(1) #F75Z-8555-AA Tube Assembly - this piece has the fitting that goes into the back of the water pump and attaches to the tube.

(2) #N811415-S309 Stud - these are what hold what looks like tabs on the tube at the back of the block (these were ordered just in case).

Just a thought brought up in another thread, what other items will be needed, IE...new intake gaskets, o-rings, special tips or tricks to remove the intake manifold and adjacent parts to get to the heater tube?

 

Looks like you've been buisy Steve

 

Hopefully that takes care of it Steve. Looks like it will be fun replacing all of that.....NOT!

 

Well the coolant leak has been fixed, it was a pin hole on the tube opposite the nipple return, the cause looked to be sediment having a sand blasting effect inside the tube. The first picture shows the tube and the next one shows a closeup of the hole. The next picture just shows where on the back side of the water pump the tube connected.

The entire intake manifold had to be removed, it took about 5 hours from start to finish.

 

Well done Steve & cudos to your buddy with the shop
