The Radium remote mounted coolant header tank is commonly required for custom Lotus applications such as engine swaps, turbocharger kits, etc. where the OEM expansion tank is no longer in an ideal location.

The main tank is a 2-piece design constructed of CNC 6061 billet aluminum, as shown below. The two halves are bolted together along with a CNC billet aluminum cap receiver which mates to any standard 32mm "Type-A" style pressure cap.

Coolant header tanks are necessary for applications that utilize a low mounted radiator, such as a V-Mount, for proper air bleeding.

The Radium Engineering tank also has an internal swirl feature, as shown below. Hot pressurized coolant from the cylinder head is sent into the vortex chamber's inlet tangentially and accelerated to a high rate of rotation. This is an old hot rod trick to help aid in deaerating the system.


The Radium Coolant Expansion Swirl Tank features three ports that include -6AN male adapter fittings (not tapered pipe threads) for a positive seal. The lower ports are machined with 10AN ORB threads. For a list of other 10AN ORB adapter fittings that can be used, go HERE. The side port is machined with 6AN ORB threads. For a list of other 6AN ORB adapter fittings that can be used.
Includes:
-Billet Aluminum Coolant Tank Anodized Black
-Aluminum 6AN Male Adapter Fittings Anodized Black
-Nickel Plated Sight Tube Fittings
-Billet Aluminum 32mm Pressure Cap Receiver
-Billet Aluminum Pressure Bleed Nipple
-Laser Cut Aluminum Firewall Mounting Bracket Powder Coated Black
-Aluminum and Stainless Steel Mounting Hardware

Options:
Pressure Caps
The optional Radium pressure caps (sold separately) allow the user to select a range of pressure. The purpose of a high pressure cap is to increase the boiling point in the cooling system providing improved cooling efficiency. Each cap is manufactured from stainless steel with a race proven high pressure valve. This is something to consider when tracking the vehicle in extreme conditions.

The OEM Lotus pressure cap is 1.1 Bar.

better results
Color: Glint Pink
I really like the packaging; you don't need to open it and spill everything—with a simple touch, you have the product. I love it and would buy it again.

Not very much dispenses with pumps
Color: Glint Rainbow
This gives out very small puffs of glitter when depressing the pump. The glitter is as expected, but it would be more efficient to just open the dispenser with how little this pumps out. I'll probably just use this for crafts instead of body and hair. It doesnt really stick either because it is a dry powder

Fine, dry glitter in a puff spray bottle
Color: Glint Rainbow
This works well if, and only if, you know exactly what it is and if it'll work for your application. This glitter comes with no adhesive or stickiness in it. It is not like a glitter stick, or glitter makeup. It is dry glitter in a spray bottle. The spray pattern is very narrow, so if you want to spray it onto a piece of paper or you body, it will show up in a clump. It does not have an airy spray pattern. To use this, you need to add some stickiness to the surface you want it to stick to first. Something like glue on paper or some sort of sticky thing on your skin that won't sink in. If regular lotion sinks in, the glitter will just fall off. So petroleum jelly or something that sits on top works best. Also, if you want it spread out instead of in little clumps as it comes out of the spray bottle, you'll have to move it around manually. On some level, to be entirely honest, I'm not sure this application method is better than loose glitter. With loose glitter, at least I can manually sprinkle it and not get a giant blob like with the spray. Also, some little bits get loose with the spray, and loose glitter in a house is just asking for forever glitter. I'm deducting one star simply because the spray delivery mechanism isn't very useful, and can actually be a liability. Unlike some spray glitters with propellant and adhesive that are more like spray paint and have a more spray paint application profile. This manual puff method just doesn't work well with glitter.
