yeh its simple as heat causing expansion of the fluid which forces it out of the tank into the overflow/ recovery tank.

when you switch off and everything cools down, the fluid in the rad contracts creating vacuum that sucks the balance back out of the recovery tank.
Do you replace the radiator capwhen you add the overflow resevoir? Perhapsthe new cap has a pressure release going one way (to get out of the radiator) and aone-wayvalve going the other (to get back in the radiator)? I'm still confused on how the coolant gets back into the radiator.

I do, however, get the vacuum explanation!
yes new cap required. at first glanec they are pretty much the same to look at. 13lbs still. it is the pressure on the spring that allows fluid out. there is a rubber seal on the recovery cap that allows vaccuum drop to draw water back in.

Nick, did your shiny tank have a threaded cap? Mine has a cap with lugs like an oil filler cap. never had any trouble getting it off. But then again, i dont rely on overflow tank level to tell me what is in the rad. The best thing about having a low water sensor is that you know instantly when you lose coolant. Especially useful if you blow a hose completely. in that situation if you dont realise whats going on, the fluid is gone before the temp gauge reacts. by time you note the smell, its too late and your engine is toast.

mine is similar to this, but with a LED warning light as well as the alarm

Yeah thread cap...basically was a cylinder with threads in it and the cap screw in.

Since I don't have a water sensor and I tend to run on the warm side when I sit in traffic it is just plain easy to look at my tank and see if I have puked out more fluid than normal when I am warmed up. It also makes it easy to remind me if the color seems wrong, or if I want to add a little more for some reason or another.

Already started? Then why in hell are you on the forum at 2:30 in the morning?
Well it was only 12:30 here in Cali, and its my first week of school so there wasn't really any homework, already did it. Mustangs always keep me up!

And to think, this all started because when I finally got my new motor started it spit antifreeze all over my newly painted engine compartment (OK, only the lower driver's side, but still....). I went to Autozone and got one, with cage, for $15. I'll be putting that old *** thing on this week, ha! As long as my new motor keeps cool and doesn't spit anymore, I think it looks be-u-ti-ful.

If you guys think the white plastic overflow container looks bad, you should see what I have, an empty cranberry juice bottle I dug out of the trash.

I've had my Mustang since February and the first time I started it and let it run long enough to warm up, it started spewing coolant out of the overflow line as the trapped air heated. Not knowing how much coolant I lost and not wanting it on the floor of the shop for kids and cats to get into, I had to shut it down. The juice bottle looks like crap, but atleast I know how much fluid comes out and I don't have to clean it up afterwards. Once I have it all together and on the road, I'll change out the OceanSpray bottle to something more suitable.

Why not get a small aluminum of s/s fire extinguisher bottle, drill 1 hole about 1 or 2 inches from the bottom and 1 about 1 inch from the top, thread it for 90 degree fittings, polish it, install the fittings with a lexan site tube, mount it next to the radiator with some nice brackets and run a polished s/s line to it?

It would look a ton better than a plastic box.
Guess what you got.

Please explain exactly what about my suggestion is 'Mickey-Mouse', my understanding of MM being something on the order of some of the 'Mickey-Mouse' regulation and practices of certain members of the military. As in:

'What a Mickey Mouse bunch of B.S.' when refering to something that is a total waste of time and effort.

Making a really nice S/S or aluminum overflow tank rather than use a piece of plastic wouldn't qualify.

It's self-explanatory.
