Re: Upper radiator hose

Lief ,pic's good,but can you include a photo of water inlet fitting??,(flat/or pointing UP ??
Francis

Francis,

Not the best picture but I'm not near the car right now so I can't take a better one. The inlet is the stock L79 "flat" inlet.

Re: Upper radiator hose

thank s Leif,upon closer review of your pic's I notice your top adjusting bar for the Alt is a bit different than the one I am using.your alt bolt is in the middle of a much greater adj. span,perhaps I have the wrong upper brace....I will check the vendors catalogs and look for one like yours.

Francis,
I guess it's just you and me now...Tom seems to have asked the original question and then just disappeared. Try this link for your new bracket.

Re: Upper radiator hose

Tom, Although not corvette correct I found that my local A/C delco siore hav a large selection of hpper rad.hoses.I took them to the car,eyeballed them and found a hose that would solve my delema.
# A C D 26036X, G M #88908735.

this hose was plenty long enough,had the proper bends to rise high enough over the Vee Belt after some t******* on both ends it looks like it grew there,best of luck,Francis....P S looks like "C/C "has the proper upper brace at least in my case,#302020,fits 64/67 cars.

Re: Upper radiator hose

OK,thanks Leif,I looked at your link and I will have to compare with the one on my car now.I don't know how I could have mixed this up while restoring,but your brace has a very pronounced 90 * bend and a much greater Adj.travel slot.....thank's

Re: Upper radiator hose

Leif, would it be possible for you to get a measurement of the adjustment travel that is in your upper alt. arm ?
Thanks Francis

Leif's looks to me like the 3-1/4" slot. Some of these braces used about a 2-1/4" slot. If that's what you have, that could be a problem.

Re: Upper radiator hose

Tom, since you have received help/suggestions to your post, it would be nice if you could respond with the fix to your problem.
It may be helpful others.

If you're still there, Tom, consider Ralph's post as well as the following:
Do you have upper radiator hose GM ....154 or equiv?
Are you running OEM ....'660' aluminum thermostat housing on OEM ....'783' cast iron intake manifold?
GM belt p/n 3847710 or equiv, length = 53.25", top width 3/8"?
GM ....559 LH exhaust manifold?
Correct pulley (alt) is 3843342 & correct damper/drive pulley is 3744043 (not visible w/out some disassembly)
Does adjusting brace have 3+ inch slot for pinch bolt?

If so, you should have a good 1"+ of clearance between fan belt and bottom of hose with pinch bolt near the center of slot. Pics below are of my '66 with identical equipment as yours. Note the clocking of the stripe and the correct position/ends of upper hose.

Re: Upper radiator hose

Francis, Joe, Jeff et al,
I have a full 4 1/2" slot in my bracket for adjustment.

Re: Upper radiator hose

Leif
Mine's more like 3-5/8", measured along the arc between inside edge(s) of the end semicircles.

Re: Upper radiator hose

Francis ,I will measure mine and get back....

Francis what does you alternator bracket look like if it is not like Leif's?
I would have bet dollars to donuts the fan belt was too short.

Re: Upper radiator hose

Ralph,my bracket looks similar to Leif's but ths adj.slot measures about 3-1/2" as opposed to his 4-1/2' adj. slot.

and yes I played heck trying to get a belt that would work,wound up with about a 34",
