Help finding the replacment part no. for a coolant tube???

[1997Ranger]

The truck I have has 2 small tubes running into the top of the engine. One of the tubes got corroded and has a lot of holes in it, so I had to move the rubber hose down to cover the tubing....

Is there any easy way to repair the tube? Also does anyone know what this is for, if there is a part number, and how I would replace it? Is it threaded or do you just pull it out?

From what I can tell it seemed to be leaking coolant. It is the one that has the orange tape on the rubber hose. I was going to submit a picture of the tubes, but I can't find any way to do it here... Anyway, like I said it looks like 2 rubber hoses hose-clamped to 2 short pieces of metal tubing sticking up from the top of the engine. One of the short pieces of metal tubing is corroded...

Thanks in advance!!

...btw, some engine stats would help for your truck.... ...and here's his pics.....

The engine is a 1998 3.0 V6 Ranger.

That sounds like the heater hose connector. I don't know about on your motor, but on my old Galaxy it was threaded in. I can't remember if it was on my explorer (4.0).. and I don' thave a 3.0 to look at.

Take a good look at it (and possibly post a pic).. if your lucky its threaded in.. and if is.. look at the "help" section at autozone/checker/kragens for a heater hose connector.

...got the pics...see above...

hey thanks for the info. I think that points me in the right direction! Well, hopefully that's the one. Even if it is threaded in I don't think it sounds all that great if the tube itself is corroded. If it is that bad it probalby will be difficult to remove it even if it is threaded. If it is not threaded, then how else would it be removed?

tbars - sorry, i was out all night so I didn't get a chance to email you the pics yet.

Thanks for posting the pics tbars. BTW, how did you do it??

In any case do you know if this is in fact the heater hose connection and I can just pick up the part at a checkers store??? Would it be fairly simple to replace??

UPDATE: I went to checkers, the only heater connection parts they have look about 2x the O.D. and are plastic, not metal. None of them are threaded, so I'm unsure if it will even fit. The guy there said some people just loop the hose and cap off the engine side but they didn't have caps. Anyone else have any suggestions what I should do or where I can find the parts to fix this and how it is done? Thanks in advance..

Okay, I took it to the auto parts store, the guy said it is definiltey not the heater. The heater hoses are going through the firewall.

Does anyone have any clue what these coolant tubes do in the intake and if they are necessary?

Where I live we don't need heat, so many times rather than repairing a heater they will just remove the heater hoses and cap them off entirely. If I did that on this vehicle, the tubes shown in the above pictures would be removed as well since they are attached to the heater coolant hoses.

I just would like to find out if it is critical to have coolant running in the intake, or if it is not, and I can just remove these coolant tubes without any signficant consequences???

...where do these hoses go to??? more pics showing where they lead to???..:scratch:

i am not familiar with the 3.0...i do know that i would only trust a dealership with a replacement part like that....

I'll try to send you more pics tomorrow. But basically there are 2 large hoses (like 2" diameter) going from near the water pump area to the heater core in the firewall. So if you can just imagine 2 hoses, I suppose one is the supply and one is the return coming from where the pulleys and belt are (like it might be a water pump).

As far as these 2 smaller hoses in the pics, one attaches in a "T" to one of the larger hoses going into the heater and the other small hose attaches in the exact same fashion in a T to the other large hose going into the heater. So to summarize, the small hoses are just tapped off in the same area of both larger hoses, about the middle, of these 2 hoses going from the water pump area to the firewall. If you can imagine the 2 larger hoses run basically front to rear on the passenger side of the engine. And these 2 smaller hoses meet the larger hoses about in the center of the engine bay and extend maybe 2-3 feet into where they are shown in the picture going into the intake manifold.

Unforunately these pics do not show where the hoses originate from, but hopefully I've described it well enough above. When I get a chance I'll try to take more pics and send tomorrow...

I'm no longer interested in replacing the part. I'd like to just cap it off. In fact, I already have by pulling both tubes off, sticking a bolt in and clamping them down. When I run the car like this, it runs fine. So there's no pressure coming out of the manifold. The small hoses appear to be sending coolant in and back out of the manifold.

Now I'd like to know if anyone knows what this is for? Why would they need to send coolant in and out of the intake manifold???

If it is for something non-critical like the heater, then I think I would rather just leave the hoses capped off rather than buying a new part or possibly a new manifold from the dealer...

Thanks!

...it sounds like what i had on an old toyota truck...and again, i am not 100% sure on yours and i will look into it myself....on my old toyota truck there was a water jacket in the intake....but again, it also had water cooled carburation...you had to drain most of the radiator to work on the carb...
...i will research this tomorrow...

...btw, where are you located??? you have no location or vehicle info in your signature...

I'm located in the middle of the pacific ocean...

Ok, I did a little reserach and I found they have heated air intakes. But those use hot air and not coolant. I am wondering if this is a similar concept, however, I do not see any type of thermostat. Looks like when the heater gets hot coolant, so would these small tubes...

HEATED AIR INTAKE SYSTEM


Definition: A system that maintains intake air at a more or less constant temperature by blending outside or underhood air with heated air picked up from a shroud over the exhaust manifold. A typical version uses a vacuum motor to power a door in the air cleaner snorkel, and a thermostatic bleed valve to control the signal to the vacuum motor. Also called Thermostatic Air Cleaner (TAC).A malfunction that prevents the door from closing can cause hesitation and stumbling when the engine is cold. An air temperature control flap stuck shut will overheat the air/fuel mixture, possibly causing detonation and elevated CO levels (due to a rich air/fuel ratio, as warm air is less dense than cold air).

...the only reference to it that i have seen is in the haynes book, and it is called a heater hose...again, if you go to your dealership you can get the correct part if that nipple is corroded and shot...

...where in the pacific are you located??? :scratch:

Ahh.. your talking the little metal line that comes out in the above picture right next to what looks like a heater hose.

I believe I've seen that on a ford 5.0 (88 f-150).. If I remember correctly (and by the way you described it) it is used to warm the intake manifold.

I think they are pressed in (not threaded) and you can bypass them (replace the T's in the heater line with a 5/8" coupler (autozone has them).

If anything, it may affect your emesions.

Well, if it is just for emissions, I think I will just leave it capped off. I also taped up the tubes so no dirt or anything gets in there.

I bet the dealer wants a lot of $ for the tube or it is a pain to remove...

If they were shrewd, they'd require you to buy a whole new manifold just to replace the tube, like it seems they do for other parts..... I'm not going to find out though, because I'll probably just leave it capped.

Thanks a lot to everyone who replied above!

 

[Tbars4]

...i'm thinking he means your vehicle may start using more gas and not running as well...these are things that happen when you play with the emission setup...your computer is looking for certain readings and if it is not found, it reverts to a default running situation for your vehicle...
...anyways, good luck and keep us informed on this thread...

 

[1997Ranger]

no problem.

if anyone can provide better detailed information on exactly what this heating or cooling system in the intake does and/or why I should not leave it capped off, please post.

where I live, due to the warm climate, many older cars which have leaks in the heater cores have the hoses removed and capped off at the engine rather than replacing the heater core for a lot of $$ (people rarely use heat here). If I were to do this on this truck, it would also remove the coolant flow into the intake. so I'm thinking (and hoping) that it can't be that critical if they piped it from the heater hoses....

 

[Tbars4]

...the capping off and bypassing is only temporary for the heater core...if you are not running the 3-4 quarts of coolant, your vehicle will not be able to cool as easily...
...i am sure you will find people who haven't run their heater core in a while but i believe to keep running your vehicle in optimum condition and to not start neglecting one thing and then having to compensate for something else...it winds up costing more in the long run... good luck...
