Correct Radiator Hoses for '72 350/200

[Roger D.]

Hello:

Can someone tell me where I can get the correct radiator hoses for my 1972 350/200 Automatic coupe?

Judging Guide
Upper, 3935466 KI AU
Lower, 3917699 KK AU

Dr. Rebuild has these
Upper, 1173854 GM
Lower, 1159761 GM

And how about the clamps? Where can I get the correct Sure-Tite worm gear clamps?

Thanks in advance.
Roger

Roger-

PARAGON lists your lower hose #3917669 with GM logo as their part #2181 for $27.00. I don't see an upper hose with the number you called out but you might give them a call. I have their hoses & clamps on my 74 and they look like the "Generals". If you call them they can let you know about the "Sure-Tite" clamp availability.

If you intend to have your car judged -- there is SURETITE and there is SureTite. You need to know what the original font looks like -- it is different than a later font. There are numbers also on the clamp which indicate the diameter in 32-inch. I'm pretty sure the numbers are in the TIM&JG -- at least they were at one time, but we did not detail the different fonts. Maybe I'll try to learn to post a picture in the next few days.

If you don't intend to get your car judged -- boat supply places have some real nice SS clamps. Be sure to get the kind that is ENTIRELY stainless. Almost no one will know the difference.

I think you got the hose part numbers for base engine WITH 4 Speed transmission. Those cars used an aluminum radiator and different hoses than cars equipped with copper/brass radiators. All 1972 with base engine AND M-40 and/or C-60 used a copper brass radiator. So, you require hoses GM #3946852, upper, and GM #3946854, lower. I believe Dr. Rebuild has these hoses both in GM and reproduction.

Joe:

You're right! I posted the GM numbers incorrectly. I was looking at the wrong one. I called Dr. Rebuild and the lady I spoke to confirmed that they have the ones you noted. The sketches the in the online catalog show the hoses have all the numbers and letters listed in the JG.

Martin, I also looked at the website of the Paragon company you mentioned. They have both hoses also and show photographs of them. But the photo of the upper hose does not show all the letters. Looks like it shows the AU but not the JP. Question: Does the hose have to show all the letters? E.g, the JG says the upper hose is as follows:

GM Part No. 3946852 JP AU

Thanks Terry, I do intend to get the car judged and need the correct hose clamps also. I'd appreciate a picture as I would like to know exactly what it is supposed to look like.

Regards,
Roger

Geoff,
I prefer to do my research using Corvettes which appear to be original. I'll stick to my beliefs.

Roger, I have a 71. My clamps have Wittek on the worm cage and Suretight in script on the band. See attached photo, hope it helps.

Man this is confusing. I purchased an "unmolested original" car (my first Corvette ever) a couple of months ago. Sounds like I may end up replacing real "original" parts on my car to just to get it to the written JG standards when in reality the specific part I have on it now may be the true original part on the car?

hmmmm........

That certainly is part of the problem with trying to judge a car using only the TIM & JG. I have only had my car judged locally twice and regionally once but I did not remove parts that were original but in contradiction to the JG. In fact, I contributed to some research on seat belts, using photos of original cars as well as factory photos, and now the JG has been changed to reflect the updated information. I don't suggest changing just to meet the JG parameters.

If you think a part is original, by all means do NOT change it. The book is a GUIDE - and that's what it says. It does not say it is the Fount of all Knowledge.

See pics attached of my 72's hoses as examples.

Also note the pic of the air cleaner hose - you won't find one like this mentioned in the JG. All original on a different 72.

Thanks everyone for the input. Since I keep my car at my brother's house (he has a huge garage and, besides, it's air conditioned) I didn't get over to look at the clamps until today. They are the suretight clamps exactly as described and as shown in you picture Ken. In fact the hoses appear to be original also. The are just old and need replacing. The heater hose clamps also appear to be original. I will purchase new hoses per our discussions either from Dr. Rebuild or Paragon (Paragon's hoses are several dollars cheaper).

Thanks also Patrick for posting those pics. I appreciate it.

Here is the style of radiator clamp I am used to seeing on 1970-1972 Corvettes. The #28 is good for only some applications. Check the TIM&JG for your engine/radiator combination for the proper clamp sizes.
