Radiator hose necks

[RedDwarf]

Ok, this is complicated (I think)....

I had a 74 truck. The radiator had the "big" upper hose neck (I think it's 1 7/8")

I swapped trucks, and radiators. The new Rad had a 1.5" upper hose neck on it (I think most of the 81-87 trucks do?)...I had it changed to the bigger size at the Radiator shop....

Well, I got a new 4 row, BRAND NEW

It has the 1.5" upper hose neck on it. What do I do? Can I get a new thermostat housing, or do I just need another hose?

I hate to have them put a different neck on there, it's brand new....

TIA

Anyone?

Did I word it wrong??

What I've seen people do is take a small chunk, about 3" or so, or the smaller hose and put it inside the larger hose. From what I remember the small hose fits perfectly inside the larger one.

thanks, I wondered about that too...reckon it'll leak? Should I put some kind of sealer in there?

I guess if it leaks you could try some silicon sealer but theirs never leaked. Just make sure the hose clamp is snugged up.

I really dont see why you couldnt just swap out the thermostat housing, they usually dont cost that much. Go down to the auto parts store and compare a newer one to the one you have.

Ok, that sounds like a plan.

Guess I'll do that first.
