87 GN Radiator hose size?

[Rogue74]

Does anyone know what the size of both the upper and lower radiator hoses are? Has anyone used Summit's stainless radiator hoses or will they even work on a GN?

Nobody knows?

I don't know the exact sizes but I just replaced mine. I got them at Advance auto parts---only took a day to get them. Tommy

Dennis Kirban has some geniune GM hoses if you e-mail him personally(denniskirban@yahoo.com). Brian at gbodyparts.com has stainless pipes bent specially for our cars, w/silicone end hoses. The top one runs straight forward from the therm. housing, and along the top of the radiator. That way it's not in the way of anything else.

I copied this from an earlier post:

Radiator hose: The lower radiator hose fits other V-6 applications and is available aftermarket. Upper hose is '86-7 specific only (GM part #25525229).

So there are no aftermarket stainless hoses that will fit on the upper, correct?

Enter this item number(7985804092) in the search bar on eBay. It's for a stainless radiator pipe(hose replacement) for our cars. Then click on "sellers other items" and you'll see all the options and upper/lower hose replacements that Brian offers(G Body Parts).

I bought some misc 1 1/4" hoses, and then a couple straight sections of chromed, under sink plumbing from the Hardware store. Then spliced things together as I wanted, double hose clamping everything.

I also come straight forward from the thermostat, up to the radiator, and then have a 90d elbow, *works for me*.
