Coolant bottle

ctrow · Aug 28, 2006

I got an 88 xj with the closed coolin system. I've gone through two over flow bottles, and it's time for number 3. Does anyone know about a metal bottle that uses a radiator cap. I've heard that someone makes one that hooks up just like the plactic bottles. Anyone know where I can find it?

Contact Eagle - he's done a retrofit using a Moroso bottle you can get from Summit. Others have probably done it, but Eagle springs to mind. Hell, if you search for his posts on the subject, you can probably find where he covered it "in the open."

Hey homey or 5-90

Could you use a a metal tank like the one above for the open style system? I am looking for a cylinder type bottle or something that fits in a tight space, but i have had no such luck? Sorry to pirate your thread.

noah

Sure - just go to Summit of Jeg's and search for "Coolant Catch Can" - all you need is an overflow, not a pressure bottle.

So, because this system does not allow you to see in, how do you refill the bottle. Is it done with removing the cap on the radiator when its cool? Its just different from what i am custom too.

The open system isn't filled via the overflow.

In working order, an "open" system should be filled to the bast of the radiator cap/neck, and the overflow should be 1/3 to 1/2-full. This allows room for coolant expansion (that's why it's there,) but provides a small reserve of coolant to draw upon in case the system gets low (when it cools off, via the Vacuum Relief Valve in the cap.)

But with the overflow bottle that you pointed me too, i cannot open the top up and pour more coolant in. So, how do i fill it?

Why can you not just go down to nappa and buy a small over flow bottle for about $5...

I actually did and it was $8. Its too big. I am trying to put it next to the fill neck instead of having the long tube to the factory local.

I see. Most of your local speed shops will have a small cylindrical aluminum unit with a vented screw on cap that would work pretty nicely.

Or try this one

Homer,

Will this work for an open system? So from the top of the radiator take the hose to the bottom of this bottle and then a hose at the top of this bottle down towards the ground as a spill over? I am asking as i am VERY interested and even as an engineer, i want to make sure i do it correctly.

It will work just fine. Run your hose from your rad to the bottom...the top fitting is the vent...fill it about half way to the top and put the cap on it.

I like those metal replacement ones. Those are pretty trick.

I do too, but i dont like the price.

I do work at an HVAC place, with a sheet metal shop. I talked to to shop manager, and he said he could make one if i had the dimensions. Does anyone have one of these, or can anyone provide me with dimensions?

Thanks for your time.

I bought the "heavy duty" pressure bottle for my closed system on Ebay, and ran it for 3 years without a problem until I went to an open system, and now its in a friends rig.

I only went open because I punched a hole in my radiator and got a deal on a new in box open radiator. It doesnt cool as well, and I'll probably go back to the closed system next time.

It looks like the whole reason for the "reinforced" label is because of the metal peice that is in it. I dont have a problem with this area, i have problem with top portion where the cap screws on. (Brand new tank and cap after a month) It looses its holding ability very easily. The only way around it that i see, is getting a metal one.

IIRC the plastic is thicker with thicker webbing as well.

the replacement OEM bottles also have that insert.
