Red Bull Can Exspansion Tank?

HI. A few weeks ago at a meet, whilst parked i noticed fluid dripping? Checked it out and the fluid was coming from the above Red Bull Can. Now this has been fine for almost a year now but was a little concerned? ie H/Gasket? but all seems well apart from this overflow? The Rad/Engine cooled down and equalised pressure and water level in rad returned to normal-ish?

So i topped up a little, made sure there was a little in the RB can and left it. Yesterday, whilst out on a spirited drive on my return i checked this again and the fluid level was again slightly over flowing from the can. Checked it this morning and all is normal?

Anyone any ideas on why this is happening now after almost a year:search:

I would be more concerned who carried out work on yor car and stuck a red bull can in there as an expansion tank!! are you sure its only just happening, could it have been happening before but you just didnt spot it??

Yeh. I know what you mean, but im certain, as i would have noticed the fluid on the drive / floor. Yes, T/F did install this as my battery is very large and no room was available. I utilised the tank for the W/I..

Well as long as your rad is full to the brim I would'nt worry about losing a little fluid, it will chuck out a little

Thanks. Is it worth getting one of those Greddy ones? I beleive they are quite small?

You could do I guess, I know blitz do one with there FMIC kit....but if you dont have a FMIC I would just get a stock one and use it in the stock location

Cheers. I have an fmic, thats why i ended up with the RB can. I think i,ll wait for a few more responses first though, thanks again..

ahh? :d

Put a Greddy or stock one in, somehow.

HI Rob. Who does the greddy one on here? It needs to be pretty small though?

I would like to know more about this aswell. I was at the meet where Dek had the problem and I couldn't understand it...

The red bull can and the pipe into the top is not sealed. It seems like the system is expanding more than the can can take. Although others say that this mod is not unusual and has worked in the past.

I work in the pressurisation industry so all the theories should be the same. Does anyone know how much water is in a Supra cooling system and also what temperature the water will get up to?

You took you time with this thread:p:d

Cheeky B@stard!!

I had been thinking about this since I last saw you mate! It's not often that I get involved with technical issues.........leave me alone!!.....

The stock arrangement has a sealed cap on it, so it wont leak out, it also has a drain thing so it will leak out if you over fill the rad (rad will fill the expansion bottle/red bull can) but normally it will draw some fluid back when it cools down.

Not sure who does the Greddy ones, mine came with the FMIC.

Get yourself down the local scrapyard, you'll be able to pick and choose any small one that takes your fancy. I believe some people have used the starlet one before.

The GReddy ones are only sold as parts of the FMIC kit.

I can supply a Toyota one to fit.

H, it'll get to 120 degrees C. Not sure tthe dry fill volume, but it should be in the spec sheets somewhere.

A solution is to get down to a local brakers and check what small expansion tanks are available to fit in the space you have. You'll probably be able to get one bigger than the RB can that will hold all the coolant that expands out. *Edit* Bob beat me to it

Or you could leave it and see what level it stays at after a few hard runs. If it stops leaking and the rad level is ok then you can probably leave it as is. Topping it up above this rad level will just keep losing that amount of coolant.

HKS do one that's available seperately, btw. I bought one from Lucifer :shudder: a long time ago

Cheers Steve!

At 120 degrees, water expands at 6%... Depending on what amount of water is in the system I find it hard to believe that a 300mm can will hold the expansion. Also if the system is open to atmospheric pressure then it will flash off into steam!!

I am more confused than ever now....

I think you advice with regard to the spirited runs is the best as the engine will get hotter and therefore the expansion will be more than normal driving. As long as the actual system is full then it doesn't really matter about the coolant you have lost!

H.

I have the same problem after installing fmic.

Would also be interested maybe in HKS one. Any links?

:blink:According to my Toyota hand book it takes 9 litres of red life coolant if that helps you H with Math:rolleyes:

P.s.....dont no if coolant will expand at the same rate as water as its denser

In which case the can isn't big enough!!.......

Although I only have info on water and not coolant expansion %'s...!!

H.

you can also use a modified catch can which looks good too

I use a starlet expansion tank. Its about half the size of the stock one and fits nice and snug at the side of the battery
