Default 87-90 "Renix" Expansion Bottle Options

Why not a normal in-line cap to a recovery tank? Not that I really mind the closed system, but jeez, this is #3 or four in 12 year.s pretty much forget it at the JY in 2013 for a bottle. Hanging on a thread with big bills due and she's cracken and pissen up on the hood. (heavy loads/steep hill found that).

I can pilfer an inline cap from my non-opped Jag-rullet. (350n'a/Jag).

Hate to chops pt4ty nre upper hose. Question is, why shouldn't it work with just the inline (14lb?) cap and a recovery tank?

I just replaced my original bottle with one from Rockauto, I think it was $22. If I have to do it again I'll go with an open cooling system.

Save yourself grief for the rest of the time you own it and do the HO radiator conversion.

If the threads match, it might be conceivable. The question I would have is what is failing on your system? The bottle crack? The cap not sealing on the neck? If the sealing surfaces mate up and the plastic threads can hold the cap on, tightly, then give it a shot. Whatever it takes to keep the pressure in...

To save yourself some dough, you could pick one of these up, put it inline on a heater hose, then run the overflow tube to the tank, without switching it. It shouldn't see any pressure, then and your problem would be alleviated.

If you really want, you can pick up a steel drop-in replacement tank, without switching anything else, but they're a bit more pricey...

Just put a Napa 703-1396 cap on it and be done with it. BTW, where's the info on my injectors?

Guess I'll just do it and fill in why it doesn't work later.

10-4 Coach. Bypassing the bottle and installing the inline cap would be converting to an open system.

Yea Xfiles, no dough (except for the "suits"), and at 270k, not "investing" at this point! That's proven solution though.

Exactly letinsh. That is what I'm talking about. An inline cap. I have one here on my Jag with a 350 engine. Heck, just now thinking, I can use my "bottle" as the overflow if I drill a hole in the cap! Granted it's higher than normal...don't see a problem there.
