HELP! Inside diameter of radiator upper outlet?

[haasman]

Does anyone know the inside diameter of the large upper radiator hose neck?

Mine has just cracked on wife's car while she is about 600 miles from home!

I am thinking of trying to insert a piece of copper pipe into it to hold it until she can get home.

Thank you in advance.

Any one?

I feel your pain.

Here's what I did for the exact same problem: (Using a 1" copper bushing from Home Depot)

Radiator Neck Fix/Preventive Maintenance

I have a new NIssens radiator sitting in my living room. The I.D. of the upper outlet is approximately 1.184", give or take a few thou., measured with a vernier caliper. The lower is slightly larger at about 1.192, if I recall correctly.

Let me know if you find any tubing this size, or close to it.

Hope this helps

Thank you both for the replies! Hopefully I can remote control this cure.

What gets me is the radiator was re-cored 2 years ago.

I knew I had seem this repair before.

I'll let you know how it goes.

Thanks guys.

OK I fixed it! I used JBWeld. Not a very glamorous repair but very well done.

The neck broke off in two half pieces. I glued them together with JBWeld and let them harden. I then took this assembly and glued it on to the plastic radiator neck where they came off originally.

I made sure the surfaces were VERY clean. I put JBWeld on the mating surfaces and extra both inside and outside all along where the break was.

I let these dry for about 15 hours. I attached the hose, drove through 100 degree weather with the AC on going up 6% grades. The coolant temp got up to 100 C. I feel this was a great stress test.

The repair doesn't leak and seems as hard as a rock.

That sounds great. You may have one or two pinhole leaks occur, but other than that the repair should hold.
