MG TD TF 1500 - Water Outlet Elbow

I'm considering having new stainless steel water outlet elbows cast, to go with my stainless thermostat housings. Can anyone confirm that the TC and TD/TF elbows are the same? I have a vague memory that there might be a difference in angle, but can't prove it with any of the cars in the shop right now.

Thanks.

I think your memory is correct Tom. I'm almost certain that the angle is different. Cheers

Tom, I think you'll find that the water outlet of the TF is totally different from that of the TD/TC. TF is OEM #AEG123, TC is SA2265, TD is SA2430. Bud

Different anamules Tom.

Right - Stupid of me to add the TF to my list - I just was not thinking. The thermostat housing I make and sell fits only the earlier T-series cars.

I think I will have TD elbows made, but am not sure if it is worth also making one for the TC.

Tom, if do make one for a TD, you might consider adding a threaded outlet on the left side, ala TF. A few of us, Jim Merz, the late gordon lawson and yours truly, have done so. Bud

But - wouldn't it make more sense to come from the thermostat housing, not the elbow?

Tom, I'm not talking of design, nor practicality, just mentioning what some of us have done. Bud

A temperature sender is best positioned just below the thermostat, so the elbow is the ideal place for it on the LHS - then you can run the wiring along the rocker box. Here is my install on the YT. The original cast iron elbow was just thick enough (3/16")to drill & taper tap to suit the sender.

If you are making them in stainless, I would think that 3/16" would be thick enough for tapping, but maybe design for 1/4" on the LHS just to be sure. No need for a pronounced external "boss" that might upset some of your market, just thicken the wall inside is my suggestion.

TD and TC have different angles

Tom, since you are planning to have castings made, why not provide a boss to accommodate a threaded plug or standard pipe fitting? When I modified my elbow, I brazed a standard pipe coupling in place to give me plenty of threaded area rather than just a few threads that a hole through the side wall would allow. Maybe that's an overkill but just my way of being secure.

I think we are talking about a different elbow - I mean the elbow that screws onto the side of the thermostat housing, not the elbow to which the thermostat housing bolts.

Ah OK Tom. I just copied the factory design as seen on all the TFs. I just misinterpreted your words when you opened this thread.

Tom, I don't think I've ever seen a thermostat elbow that has had any rust damage. I can't imagine a market for stainless steel ones. Bud

Bud,

I've seen a number of them with erosion where the rubber hose is attached.

You're right, Gene. I have seen some there. Guess I was concentrating on the mounting area. Bud

I purchased a new outlet of the type shown in PJ's photo from B&G installed it, filled radiator with distilled water ready for inhibitor which I was getting in a few days time. before adding inhibitor I took the top hose off to put some stocking over the outlet end to stop crap getting into my new radiator, well when I removed the hose I was astounded to see the aluminium outlet starting to corrode already so I would be in the market for a stainless steel outlet for my TF
