Bought a 2000 ford explorer for swap

[chuck1022]

I have been really enjoying driving it. I have been tinkering with it and found the coolant crossover pipe has a pin hole in it. Anyone replaced one of these before? What's the PIA factor?

Not too hard to change.
Here’s the part number I bought from ford dealership

Heater tube

F77Z-9D424-BA fits from 2/7/97 through 2001

That is also a sign that when you do the swap, change all the core plugs in the block. They are only a little thicker than the tubing and are probably pretty crusty inside. So much easier to do while the engine is out and only a few bucks for a whole set.

Weather you want to do a preventative change of the timing cover...

Got a leak. Anyone know the part numbers for a new one. My motor came out of a 99 Mountaineer. Thanks Karl

Thanks for all the info and part number

I almost have it all torn down. So far I have only lost 2 half inch nuts.!!!!

Anything I should change while I have it torn down.?

Seems to be a lot of black soot in the plenum chamber

I always changed the timing gear set, new water pump, and new oil pump. Clean out the oil pan and it gives you an idea on how well the oil was changed...
As mentioned above, consider the freeze plugs, best time to change them is now.

Ok.....been working on it a little every night. Got everything off but plenum.

QUESTION

is there a gasket in between the plenum and intake????

Yes, it technically only moves air, so I tend to reuse them a time or two. I would start with a fresh one for now though

 

[chuck1022]

Ok....I ordered the part and this came in. I unscrewed mine from the manifold....this looks pretty damn close.....minus the threaded part that goes into the manifold

 

[chuck1022]

Should be a jam nut type thing there

 

[chuck1022]

Somebody has run into this before. In all fairness...I should be asking in the Explorer forum

i had the same question not long ago . the bolt on the bracket is all that holds it in there. i guess the pressure isnt enough to blow it out

 

[chuck1022]

I take the nut off the old one and use it on the new one?

 

[4x4man514]

thats right. as long as it will come off. i had one set of pipes that the end of the pipe was flared so the "nut " would not come off. so i had to buy a new one and it just slid on over the o rings. it was a tight fit.

so yes as long as it isnt flared you will see once you remove it it will look like your new pipes.

 

[904Bronco]

You know it was just a week or two ago that someone brought up this same issue with the new pipe and extracting the fitting off the old coolant pipe....

Sorry I don't remember the tittle, but I will do a short search...

 

[904Bronco]

Okay, it was a few Weeks ago...

[chuck1022]

Ok....I hope I can figure this out

 

[chuck1022]

Got it all apart!!!!!!

Is that orange thread lock on the nut that goes into the maniford????

Blue 242 thread lock but I saw red stuff too

 

[904Bronco]

It is a thread sealant, not red loctite.

You can use teflon tape, thread sealer paste, etc. Make sure the threads are cleaned up some on both ends, and you can crack the aluminum on the lower intake if you get a little overzealous in screwing the fitting in the manifold...
