needs some help from owners of 87's that are very original

[weider1717]

I need to know what clamp came on the coolant tank hose stock. My truck when I bought it years ago the owner had put one of those after market tanks due to the original tanks leaking I assume and it had a regular ole #6 hose clamp on it i have put a oem tank back and looking at that clamp I would just assume it isn't original that GM put that kind of clamp on it..looks ghetto.

so if anyone is nice enough to take a look or even a picture I would really appreciate it because none of the google images shows that area in the engine bay it's always blocked!

Not sure if it's the same as an 87, but my overflow hose clamp looks like this, and it's olive drab in color.

[weider1717]

thats what i figured! thanks so much. Now I got to see where I can find one.

[MikeB]

In fact, virtually all of my smaller hoses use that type of clamp -- fuel line, tank vent lines, lines to evap canister, etc.

I just stepped out and looked and mine has that clamp you describe on the radiator end of the hose.

I am talking about the coolant tank end so just to be sure you're saying yours has that same clamp on the tank end that is on the radiator end also correct?

thanks again

No, the radiator neck end.

My tank has a nipple that the hose pushes into. Looks like there may have been some kind of clamp on the nipple at one time. Weird, huh?

Ah ok well I have the correct clamp to the radiator end and my tank indifferent mine has a nipple that the hose fits over and thats where the regular hose clamp is that I am assuming isn't the way it came.

[weider1717]

anyone else? as I still don't know. thanks

Keith is the first one that comes to mind to answer this best...perhaps he's lurking.

[Keith Seymore]

Sorry - I kept forgetting to take a pic.

Mine has a small crimp clamp at the surge tank. It is called an Oetiker clamp, after the manufacturer.

The clamp Keith showed is original for 85-87 and through 91 on the RV designated crew cabs, suburbans and blazers.

The pic above that with the was the 81-84 overflow/recovery tank.

Yes - mine is an '87 and I would expect all 87's to be the same (regardless of build location).

It's pretty damn cold outside so I won't be stepping out to check right now, but I am pretty sure my 87 has the style like MikeB posted only they are black not green.

[ZacharyDouglas1992]

just to solidify the above, my 87 R10 also has an "Oetiker clamp", which before this post I did not know the name of haha.

Same here pal now the question is what size and where to get one! I assume it's black or bare and just dirty.

[weider1717]

anyone have a gm part # for this clamp or able to tell which size on ebay etc would be correct I don't have enough info to order one. thanks

Part number not available; Service parts shows a worm clamp.

You'll need the crimping tool as well

[N2TRUX]

Unless your are dead set on a 100% accurate restoration, I would use the clamps pictured. They are a GM correct style, and much easier to acquire and service.

[jetmech85]

Try MSC Industries.

I have had my truck since new and the crimp clamp is what mine came with.

But! there was a recall on the surge tank's cuz the nipple would crack and fall off, GM replaced the tank with a new one that contained a brass tube in the nipple. When they replaced mine the replacement tank had the crimp clamp and hose attached but they put a worm style at the Rad end. I cant remember if there was a crimp style there or not from the factory.

[87ChevyR10]

My truck has the same clamp as Keith shows.

I'm right there with you on keeping the truck 100% original! Keep us posted on your searches!
