The picture below shows part of the cooling system and heater hoses. The red arrow points to what I've always heard of as a nipple, but I'm not sure what it's really called. It's where the heater hose attaches to.

My problem is that I've been tracking down a coolant leak on this newly rebuilt engine that's never been started yet and was thinking it was coming from the water pump inlet pipe. When I took the hose off the yellow highlighted nipple, the metal nipple broke off (see second pic).





I'm assuming that this is a part that just gets pressed in, can anyone confirm?

If so, anyone know of a part number if this is the case, or if a company like Napa carries it? Can this be installed using a rubber hammer?

Thanks for any advice!

 

Clean out the hole, and tap new threads in. Get a fitting for it from ACE hardware.

There don't appear to be any threads either on the nipple or inside where it should have been, which is why I was thinking it was pressed in, but I'll keep this in mind.

 

its pressed in, tap the hole for threads and then place a fitting inside there. The tube is hard to get out from a head if you wanted one.

 

Bah, it's just your car's way of telling you it's time for an upgrade. What engine do you have?(Looks like d-series)

d-series- Y8 manifold
b-series(not gsr)- AEBS time

either way it won't cost too much, probally spend some of your x-mas money, and make more power too. I just wouldn't waste the time. How the hell did you break that anyway?

I would like to know this also

 

Yeah, I looked at it for several seconds thinking the same thing. I just pulled on it, and not hard either. So, I'm guessing it's not my water pump inlet pipe. It's almost clean on the inside also. This is from the CRX SI I bought for $200 with a blown head gasket. It's better to find this now than an hour away from home!

I'll check with honda and let you guys know what I come up with. I always get the weird issues!

I agree. The best fix would be a new intake manifold.

Once I pulled the vacuum port in the intake for the brake booster. It was pretty tough. I had to use some map gas and some channel locks. I bet it will be damaged before you get it out.

Looks like it rusted.

 

It's a "press-in" fitting from the factory.

My recommendation would be to look for a thread in fitting and then tap the hole for the fitting. This assumes that there is enough material around the diameter of the hole.

Another problem that you may bump into is that all of the hose fittings I've seen are for standard american hose sizes and will not give perfect fit for the factory metric size hoses. Plan on having to tighten down the hose clamp a lot and not using the standard honda clamp.

Theres no doubt in my mind that it can be done. But its most likly going to bend the pipe and or crimp it than be feasable to take it out and press it back into the hole.

That piece rusted an broke off. I've seen it happen before. Use Antifreeze instread of water.

 

Do you have suggestions for a replacement intake if I don't get this one fixed? I'll try tapping the hole first, but if I have problems, I'd like to have alternatives. If there are other intakes out there that wouldn't require a lot of money or a lot of tinkering then I may be interested, but I don't want a science project! Thanks!

 

This is my first option. I've tried everyone but Ace, I'll go there next because nobody else has anything that will fit.

I would probably just replace the whole intake, if your not looking to spend a lot look into the aebs one, or just by a stock replacement.

 

If you have an just an old A6 in your Si still, then get a 96-00 EX(D16Y8) civic's manifold. Get a 5-speed one because it will go on with less mods. You can probally get them at a junk yard for a reasonable price. I got mine, w/ my z6 swap for $100 from a local yard. I wouldn't pay more than $50 for that manifold.

I've got a 5spd Z6 manifold sitting in my garage from a swap...has rail/inj's/tb

Let me know it's collecting dust. $50?

Vince

 

Get one from a junk yard or someone else on this board. Thats the other alternative unless you want to tackel this project.

 

I am switching over to the Y8 manifold on my A6 this week, but I will have two spare A6 manifolds laying around when I'm done, hint hint.

 

that happned to me. i just swapped.
