Aluminum Coolant tank
 

Does anyone make an aluminum coolant overflow tank or has anyone ventured to change from the ugly oem one. I have found several aftermarket tanks. Im thinking about just getting one or two and trying them out. I have a FI setup and some of the pieces in the engine bay really take away from the overall look like the coolant tank and the winshield washer fluid tank soo im looking for options. Just curious to see what people have done.

Well, I painted mine. A lot of people paint the washer fluid bottle. I also did the coolant tank, but then I had the damn sensor go out, replaced the bottle, and haven't repainted it.
The sensor itself can actually come out of the bottom of the tank, but I don't think you can just buy the sensor itself.

Yeah i want to steer clear of painting i rather have the aluminum look but it seems painting could be the only current option

I am actually in the starting stages of developing one specific for the 8.

^ HURRY UP lol ill be in the beta tester group lol

im down for one too

I am interested - keep me informed please.

My prototype model almost done. Fully serviceable. With level switch. Still working on the wall thickness reduction and satellite tank (for additional volume and refill purpose). No more cap and pressure can be monitor and control.

Here's a pic of the main tank when I was 1st done (just brought back from the machine shop). When I've finished, I'll make a thread. Progress slow because of my job that let me has limited time to stay at home.

dude, you should look around online, there are a lot of them...and different types too...LOL..if you wanna keep the same position, you should google it...alot ...
let me know if you get ready for it because i took the whole weekend to do that, and i found out that there are alot..

^ I found alot of things labeled coolant resovoir but they were really catch cans. The only possible can i saw was made by weapon R.

moroso do coolant tanks I thought?

Unless they have just started making a new one, their existing tanks are designed for Detroit iron and do not fit well into our engine bay as well as not having a sensor tapping.

there is no coolant tank out there made for our cars.

US$565 per set, shipping not include. No level switch. Uses 1.3bar cap.

^.......Yikes! :scared:

All that crap, $565.00, and no sensor!

What are all those things for???

Can't figure why you would need all that??

that does not even look like is made for the rx8 FAIL

Japs stuffs always expensive. The coolant system claimed to reduce heat by 5 celcius but don't know how true. Anyway, I'm not gonna buy it for sure :D

Well maybe this thread will get someone to thinking of being an inventor and making one. As long as it will fit into the space that is now provided I will purchase one.

^ Agreed as long as its not crazy expensive. While they are at it they should make a rotor shaped windshield washer fluid bottle............ in aluminum or something.

We are in development of one currently. In fact we have 10+ items in the design stages for the Rx8. I do not want to get into much detail at the moment since we are not a paying vendor here yet. We are a vendor on RX7club.com and have been doing product design and development for quite sometime for the old school Rx up through the FD. http://www.re-speed.com

Out of the same 3 canisters in the background, I am fabricating a 4th one to be the coolant reservoir. I pretty much have it complete, outside, will post pics very very soon. Even though I installed the little aluminum one the same way the stock one (other temp photos) goes, it was not enough space and it would end up spilling out all my reserve!!! Car would overheat after a whole day's worth of use. So far the temporary solution is the best since it's the same stock reservoir, just moved to where the air pump used to be. I also added a pressure release cap with same color (burgundy) so it matches quite well.

Update:

NOT FINISHED, BUT FUNCTIONAL

I need to have mine in the area of the stock coolent tank.....I don't have room elsewhere.

Finished product. I am going to relocate the coolant one, the hoses at bottom hit the wheel well, the windshield washer reservoir can go at the very end, or even better, oil catch can, doesn't do much anyways, LOL!!

Same for you Phil, make one out of the same canisters of your trio. You need 2 bigger sized hose barbs for it to work propperly. And you need a pressure release cap (not like mine, a regular one will do, I liked mine cause of the color)

I did look at that but when I figured the capacity of the coolant tank I found that room was a real problem. The two tanks on the left are for oil injection, the tank on the right is for windshield cleaner. The small tank in front of the trio is the oil catch can. Due to the fender well limitation I could not make another tank fit into the space that would have the capacity of the stock tank.

I did noticed today that when I boost for long periods of time my cooling system pressure rises and it loses a bit, not much, had to put about 16 ounces over the weekend, but I did quite some acceleration (no racing :suspect:) and had the A/C on all the time, it's my weekend car... :)

I am thinking maybe if I leave it 1/2 full it will have the space to build up the pressure and not spill any out. Maybe since the reservoir tanks only go 1/2 full for that reason? Any ideas?

Very nice!!! Where can i get these?
Can i buy it from u? :)

Murray Speed & Custom shop. Mazsport used to sell 3 of these cannisters, I have a 4th one for 2-stroke for the SOHN adapter. It is not for sale, sorry. Still using it.

haha.... No worries... Thanks for the head's up!

Nicest catch cans i have seen so far bro !!!


CHeers!@!

is this the one? is the orange cap seperate?

Thanks. You should be able to fabricate them as well, wasn't that difficult. I saw the pic of one you found, that's not the one, but you can probably do the same mods. These are aluminum but chromed.

i too have used these tanks to make my catch can,sohn, and washer fluid. you can also buy them here also ask about better pricing if you buy more than one. i think i paid 65 each for 3 and 10 bucks shipping.

nice bumblebeerx8! these looks exactly the same... are they?

do we still need to any mods to change these to cater to the sohn & catch can? (i know the washer fluid needs to change the adapter below)

Yep, those are it! Thanks BBRX8.

For oil catch you don't have to modify it, but yes, you need to modify one for the SOHN adapter and one for the windshield washer. For the SOHN adapter you can switch the cap on the bottom and the fitting on the side, but they are slightly different thread, you can probably find the right thread hose fitting for the bottom at an Ace hardware store, where I bought mine from. And for the windshield washer I cut the bottom the same size of the windshield washer pump and used the same rubber seal and it worked nicely... For radiator reservoir it's more modification, shown above.

how do you guys bypass the coolant level light?

Unplug it.

your engine bay looks nice 9k.

Thanks man, it is a work in progress.

I'm trying to clean my bay up a little more during or after my rebuild. I still have the stock coolant tank for now though.

So how much for a tray and coolant tank 9k?

I'm curious if there is a functional reason for fabricating a shield behind the radiator? I thought having it open would help blow that hot air out better, especially with a vented hood.

because you dont want the air that has been heated up by passing through the radiator (and in 9k's case, the intercooler) to heatsoak your intake piping.

Yeah it definitely controls intake temps, big difference without it. Also, it is debatable but it also helps direct air down and out the bottom of the engine and thru the side vents. I was told that if not it creates a high pressure area under the hood with no place to vent properly.

This is the tank i am using check it out ----> Universal Coolant Expansion Tank

Been eyeing that one for a while, but between that and the required fittings it just gets spppensive

Is it much of a problem for the bottom of some of these tanks to not be above the top of the radiator?

It hasn't been a problem for us, both Hoss's setup and mine are working well so far.
