Waterpump hosebarb

[ginoz28]

Today I got the hose plugs to block off the hose barbs that go to the heater and when I was pulling the left upper barb the whole damn barb came off! WTF!!
I just wanted to see if I can reinstall it or can I put plugs in the holes?

PLEASE HELP

Plug it. Either have it welded shut, or see if you can find a freeze plug to drive in.

Those are pressfit to the pump. But it you are not gonna use the heater core you could find aluminum plugs and have them welded in.

[ginoz28]

I was thinking to about small freeze plugs, but didnt know if they made them that size, but I wanted to see if yall guys had a better idea. And I dont know anybody around here who knows how to weld aluminum.

I wanted to ask to what do the 2 hoses on the driverside of the block go to?

[Fastbird]

Oil Cooler. One line to the barb at the bottom drivers side of the pump, the other line to the port on the bottom driver side of the radiator.

Thanks guys Im gonna go tomorrow and see if I can find the freezeplugs.

pipe tap it. iirc its a 3/8" npt for the upper and 1/2" npt for the lower.

[ginoz28]

If I cantt find the freezeplugs I'll try and tap it.

[ginoz28]

I couldn't find any freeze plugs and then I was checking the barb against a 3/8 thread and the thread looked to small compared to the barb. So I just got some jb weld and put it back on and I'll see what happens. It says its good to 550 degrees.

There is a difference between regular nut/bolt 3/8 thread and NPT 3/8 thread.

Big mistake on the JB Weld. It will eventually fail. The cooling system is under 18psi of pressure.

NPT stands for National Pipe Taper. The threads are tapered for sealing pipe threads. They are not the same as standard nut/bolt threads and the two are not interchangeable.

I know that I needed a ntp tread tread but, when I put it next to the 3/8 plug the barb was bigger or the same size at the top of the taper on the threads so it would of been loose or the tap would.have just slipped straight in.

Clarify here. You said "when I put it next to the 3/8 plug", what are you talking about?

A 3/8" NPT pipe tap is .675" in diameter while a 3/8" standard tap is .375". You need the pipe tap (assuming the 3/8" pipe tap is the correct size).

When you talk about NPT pipe threads the designated thread pitch has absolutely NOTHING to do with the actual size of the pipe/fitting.

[ginoz28]

What I'm saying is it would have fit like this with the bottom of the thread not touching the walls and not sealing anything. And if you bottom out the tap,your just straightening the walls and it won't have the taper to be able to seal tight.

For you to tap the hole for NPT threads you would have to measure the OD of the current hole, then determine what size the closest appropriate NPT threads would be (drilling and enlarging if need be).

did you check the next size up tap?

[ginoz28]

Now I'll know what to do when I have it out of the car, I'll drill and tap the inlet and outlet for 1/2 plug.
Thanks for the info guy's
