I kind of just stumbled across this solution when I was doing my radiator mod. I was having problems with overheating when I was using the electric fans. So in order to use the stock clutch fan I had to get a custom Griffin radiator to install BELOW my radiator support. Obviously under the rad support it would be awkward to have a radiator cap on top of the radiator so I got a griffin rad without a radiator cap and needed a external breather. I THEN found out how USEFUL the damn thing was....

You can still use the breather. Get one and install, when you bleed your system hang the breather tank from your hood or somewhere high. Keep the rad cap off and run the motor, monitoring coolant level and filling as necessary. It took me like 30 mins to get all the air out, but, then after that its best you try and find someplace alittle higher then your engine to install, but, if not, you just won't get the continuous bleeding of your system.

LOL...back in 2005 I was happily purchasing my first mod (set of coilovers) for my 240 not knowing that it was about to be the most monetary consuming project I ever would embark on in my life. LOL

Yeah just mount it on your firewall and it would be higher then everything!

This is interesting, the knock offs work just as good as SARD/GREDDY even MEGAN? there seems to be 2 different "main" brand knock offs, this one is only an extra dollar and seems better then the other (price= shipping+item total)

Due to using Ruckus-Racing mount kit + Nismo KA mounts, my intake manifold sits higher than my hoodline. I had to have the rear of the hood raised to fit the 25 in there.

There is no point higher than my engine (inside the engine bay). This kind of defeats the purpose if I won't be able to have continuous bleeding, in my opinion.

Get a GReddy or front-facing plenum. I had this same issue. Now the highest point on my engine is the front of the timing cover.

*gasp* ? I don't think _any_ of us have a _clue_ as to what you are talking about! It's sad to think that my freaking Lexus was cheaper than my 240..

I have some shorter ruckus-racing brackets in the mail now...so my motor should sit right. I'll be purchasing one of these within the near future.

the tank just arrived, overall it looks exactly like the greddy unit, im very impressed of the craftsmanship that the hong kong sweat house kid put into this unit, for under 60bucks shipped, all i need now is to get off my butt and weld a bung to the air bleeder bung

none at all, i made my own lower rad hose adapter, tapped a 1/8th npt fitting into were the rb26 has its bleeder screw and ran to the upper inlet on the swirl pot, installed a greddy dummy cap on the rad and ran the overflow coolant hose from the top of the rad to the swirl pot, and the bottom of the swirl pot runs back into the lower rad hose returning coolant to the motor.

the lower rad hose pulls coolant thru the two highest points , one located on the motor, ie the bleeder hole, and the highest point on the rad, were the stock cap would normally be.

ill send you a pic of my set up, if youll post it on here for me?

thanks, like i said in the email, the two upper inlets on the swirl pot go to the rad over flow nipple under the dummy rad cap, and the other goes to the breather hole on the motor, the lower (not pictured) goes to the lower rad hose, hope this helps!

Can you see the coolant swirling with the cap off? lol

My car is in the shop now getting the lower brackets installed. I'll be ordering this once I can confirm that the motor sits low enough to justify buying one.
