Topic: 1966 200 I6 w/o A/C heater hose elbows

[jgidley12]

Hi...I am totally redoing my heating/cooling system from radiator back to heater and have some questions that I hope somone at this forum can help me with.
My car does not have either the little short 'nipple' that some dealers say is for a 1965 only; nor does it have the elbow that most all dealers say screws into the intake manifold on the passenger side of the engine. I have tried to research this but can't seem to find any definitive answers to my questions. I have read in this forum about some San Jose cars haveing a 90 degree 'tube' that screws into a fitting at the intake manifold but there was no explaining in that discussion whether the car they were showing pictures of that had this 'tube'...if it was with a/c or without. In any event, as I said...most mustang dealers list this 'L' shaped elbow as the part that supposedly screws into the intake manifold but they don't list any explanations about whether it's with a/c or without so...I am just very confused about these parts considering that a previous owner of my car either lost or forgot to reinstall these nipples and elbows when rebuilding the engine, etc.
Does anyone have pictures of a 1966 without a/c 200 I6 manufactured at the Dearborn plant in June, 1966 what elbows or nipples it SHOULD have? I have seen two cars with I6 on Ebay that had the elbow on the drivers side or water pump side but none like that on the passenger side. Your help would be greatly appreciated. Thanks, Johnnie

Here are the elbow and nipple in question from the mustang dealers
Does anyone have a 1966 200 I6 w/o a/c that uses either one of these fittings? Or does logic suggest whether either or both should be used? As I said...my car was manufactured in Dearborn  June/1966 Please offer your thoughts on these fittings.

The original '65-'66 200 I6 Water Pump Tube is not being reproed.  It is a completely straight tube with a Hex Nut moulded into the top of the tube.  It is around 5 inches long.  The replacement for it today is the 90 degree tube that is in the 2nd picture above, and that is what the vendors carry.    The short fitting piece in the 1st picture that is pictured above is for the top Passenger side of the head.  It is located all the way in front on the head closest to the radiator.  Both pieces are what is used today when you are missing both original fittings.  The short fitting is very close to the original fitting, the 90 degree fitting with long tube is not.

It would be nice if someone would repro the original straight tube with built-in Hex Nut one of these days.  I would think Scott Drake will get around to it eventually.

So does the 90 degree fitting screw into the water pump on the left or drivers side of the engine? And the little short one into the intake manifold on the passenger or right side of the engine?

Is this the Tube you're referring to or looking for? It's identical to my original old rotted Tube, around 3" long but don't know if it was originally chromed; I'll have to remove the chrome if not. It's confusing as it's nowhere near as long as the repro Tube you find in catalogs, which isn't correct anyway, but what was the correct length for Dearborn 200's...3", 5", both? Granted, my Engine is a '65 but if both years used the same Tube, then this one, I would think, is correct...not 100% sure though.

If it is correct or acceptable for Concours Judging, then you can find it listed in most catalogs as being used on the 68-70 390GT and 428S/CJ at the Water Pump. If it needs to be the longer tube, I wonder if you can use the one listed in the catalogs for your year and simply cut off the 90; it'll end up looking like the one in the 2nd photo. So that the Heater Hose has some bite though, you may have to create a couple of grooves of your own, similar to the original.

P.S. - where you see the Brass Fitting on the left in the first photo is where the short Nipple goes; Brass Fitting not used for non-A/C cars, short Nipple threads directly into the Cylinder Head.

Is there an MCA judge or anyone else out there who can provide clarity on these heater hose fittings? Seems I am more confused

This is the water pump fitting on a '66 engine I have. Unfortunately I don't know what plant the engine was installed at, or if it even was in a Mustang. The P.O. for my '68 took out the S code motor and installed this six. He said it was from a '66 Mustang. No mention of whether the donor car had A/C or not.

It is similar to the one that suskeenwiske posted photos of, but with less tube above the hex flats. May be shorter overall length too.

Sorry, the pics are not the best. I can take better shots and/or get measurements if it would help.

[jgidley12]

Thank you all for the pics. I believe I have it understood now. Thank you so much for all your input,  without which I'd still be scratching my head.

Ha!  I always wondered about that "68-70 390GT and 428S/CJ" pipe.... Whether is was the right size to fit or not...It looks like it does! I never wanted to "bite the bullet" and buy one to see if it fit or not.  I guess now we know!  Thanks for that info.  It's about 90% close to the original I-6 Straight pipe.  It's not exact, but it's really close, and close enough.  Much better than that 90 Degree long pipe which really stands out as not being correct.

I can't remember...What vendor carried the "68-70 390GT and 428S/CJ" pipe..  Was it Mustangs Unlimited...or NPD...  I know that it has to be one of the two..

NPD lists it as their Part Number 18599-6A. I would have to look through other catalogs to see who all carries it.

This might not be acceptable for a concours restoration, but for a driver Summit sells a very similar part in stainless:

They have a variety of lengths, thread sizes, etc. The one I linked to may not be the exact correct one - I don't have measurements with me right now to check.

he P.O. for my '68 took out the S code motor and installed this six.

Aww, why would somebody do that?!  Such a sad fate for an original big block car.     Hope the PO at least kept the 390 with the car.

He was commuting 35 miles each way to work and wanted better mileage. He sold the motor & the C6 and I was unable to track them down. But I'm slowly (VERY slowly  ) accumulating what I need to put a correct S code motor back into it. The six is now the centerpiece of a 1929 replica speedster (long story). I have a few pieces that aren't needed for the speedster that can go to new homes. The water elbow is one. I will post it in the for sale section when I get the chance (may be awhile...).

Dearborn Classics carries it, their P/N is 64-73869:

http://www.dearbornclassics.com/heater-hose-nipple-390-gt-fairlane-and-torino-1968-1969.html

The proportions are slightly different from the 6-cyl. elbow, but may be very hard to notice once installed.

[NEFaurora]

The 390 pipe definitely looks closer to the original I-6 pipe than the 90 degree elbow pipe which does not look original at all...

It's good to know that the 390 straight pipe fits...Looks good too..though it's a bit shorter and has the hex nut a bit further down.  It still looks better than that 90 degree repro pipe.

I think that I'd rather order the 390 pipe through NPD as Dearborn Classics tends to be a bit pricey.  I'm curious to know the price difference between the two..
