engine and drivetrain Bypass Cap

[crosson9]

Hi Everyone!

         Replacing the water pump on my 02 and noticed that a bypass cap was used to block off one of the outlets. What was used was a 3/4" cap which is in bad shape, so I would like to use a proper fit 1" cap. Local autozone does not carry a 1". Any suggestions where to get one or other options? Thank you guys, you always have the answers. -T.J.

Home depot plumbing?

No answers, just a question-

 

what's being bypassed?  

 

The only thing that pops to mind is an intake bypass for a dual carb manifold heater...

Yes TobyB, I believe that is what is being bypassed.

So you do not have heater box circulation?

If you have a heater box, just as easy to get the bypass tube and hook it up proper.

I don't see where crosson9 has stated whether he has sidedrafts or a downdraft carb.  If a downdraft, then he has no manifold heating now.  If not then plumb it up as supposed to be.

I've used 2 approaches with that- either use a short piece of hose and an internal plug that fits inside the hose,

or run the rubber line forward, then splice into the heater line that goes to the back of the head.  I put a small

restrictor in there, as it's a 'heat leak' but I found that it helped with bleeding the air out of the head.

 

I've never seen those caps for cooling systems, and using household plumbing on cooling systems would make me a bit nervous.

Yes I have side draft carbs on the car. Plus I live in South Florida so there really isn't a need to have a heater in the car.

Then I vote for the short section of rubber hose and an internal cap.

I've seen various plumbing caps that are designed to cap off a pipe. AS long as its long enough to slide into the heater hose for two clamps, it should hold.

 

I am envious of people that don't need heaters.

TobyB, what would be an internal cap? links or pics to give a clear idea. Thanks you all for your input on this!

 

Also, hose clamps. Some better than others or are they all the same?

Piece of rubber hose and a bolt of your choice that fits...

Go to PexSupply.com, search for copper caps, you will see what I was suggesting.

Thank you again.
