Well, first of all, i think that is the water pump that the line is connected to. It look like that has been occurring for awhile due to the rust. I would ask the last owner about it. He should have seen it. Did he let you drive it before you bought it?

it's the coolant bypass tube it leads to the heater core line in the back.

bullshit i work for an advance auto and if you ask then the company DORMAN makes a bypass tube in the help section. you might want to consider putting on a new waterpump while your in there too. just so you dont have to mess with it later.


bolt ons for now..... split port swap very soon....

Yeah!!! Like 8000 RPM!!! High RPM puts a LOT of pressure stress on Ford heater/coolant systems Find the weak spots you will!! Be glad coolant was not spraying on your front seats like when those *%&^&)#$% heater cores blow out!!!

It's a "blown heater hose bypass o-ring at the water pump". They are weird now since they have that wonderful o-ring+clamp thing to save money - I guess The "O"-ring failed... A minor problem... The car has probably been sitting for awhile... Print and takes you pictures to NAPA instead of "o'reilly's" and expect to pay $5 to $10 for the parts to fix it Know the "'Ford Mustang V-6' and 'year'" of your car since that is the first thing they will ask you. They will then just 'go get you' the stuff

It's trivial... Slow down, and it will seal itself... But fix it, and keep on driving!!!

You should not have to remove the manifold. I think all you need to do is:

Be sure the engine is cooled completely down.
Remove the clamps on both sides of the hose. Some coolant will spill but not much is up there.
Clean up any fittings and put the new stuff on.
Add some coolant to make up for what was lost.

That should be it. Sometimes those hose go under the manifolds and are harder to reach, but yours in the pictures looks really easy.

Why didn't you just buy a 5 cent o-ring? There's no need to take off the intake. There are some small bolt on the backside of it, but you should be able to get to them.

Intake Waterpump Bypass Hose Question

Hi, I am a female, 39, but know a bit about cars from my father. Just bought a 99 Ford Mustang, 6 cylinder, 3.8, and I am having the same problem with this water pump intake hose. It busted a leak. Man at the junk yard even had problems getting it off and said the intake would need to come off, then another guy said nope, it didnt, and another guy got it off. It seems its bolted in under the manifold in the back and that's the big hassle with this thing. I'm low on funds and was hoping this was a simple procedure but I'm guessing it isnt! My question is... if the intake doesn't 'have' to come off... is this something someone with little expeience can do? I mean I can use a crescent wrench, a screwdriver, and basic tools, etc, I'm just not a professional mechanic. Is this something that an amateur can do? It sounds like alot of problems but also since I'm a female I have little hands, and that might help, but with little hands comes little strength! It is the exact same hose shown in the pics on this forum. Also... I had read around and seen some things about bypassing it. Is this something that can be bypassed considering its a bypass hose? I mean, what's its purpose anyway! Is it necessary? Thanks, any help will be greatly appreciated.

well i ended up takeing the manifold off...it was alot easier...
well the metal tube i had to end up ordering from ford. it was a 100...and of course you will need to get a new gasket for the intake aswell...but overall it was super easy, probably took about 10 or so minture to get the intake off, and the tube, maybe about 15 or so because the bolt on the tube was rusted so i had to use some penetrating oil...but other than all that it was EASY!!!

There is a stud-bolt that holds that pipe to the intake manifold at the back and also supports one of the ignition wire standoffs. I believe that stud-bolt mounts to the lower intake manifold. It is fairly easy to remove the upper intake manifold then everything should be accessible. While you are in there replace all the hoses and get new coolant in the engine. One of the heater core hoses pretty much requires removing the upper intake to replace it.

I was replacing my waterpump and the guy that was helping me crimped the coolant bypass tube a little bit right above where it eneters the waterpump but there is almost an inch that goes into the waterpump that is fine so we thought it would be alright but coolant started to spray out the top is this because its crimped or could i have broke the new oring by accidant
