What Are The Weakest "supporting" Parts Of The Rb25det

[made_guy]

I have removed the stock coolant bleed and fitted the header tank. The bottom fitting is teed into the bottom radiator hose, third from top goes to the radiator overflow pipe and the radiator cap is replaced with a straight blanking cap, second from top goes to where the old bleed went (so it's the high point to allow any bubbles into the tank) and the top one goes to the overflow.

So basically any air/steam is now going to the header tank which is the high point and bleeding off to the overflow, rather than being trapped in the engine. An extra bit of capacity would probably help but then mounting would become a bigger hassle.

I have clear lines on it too rather than the blue in the picture. You'd be surprised how much froth comes out of the top of the radiator after a session on the track. I thought i'd done the head gasket the first time i saw it.

hey dude, where did you get the clear lines from? are they silicone or some other plastic?

cheers

my tank came with them. Silicone by the look of them.

Thanks Nismoid One more possibly stupid question - if the new radiator I'm getting is 4cm thick instead of 1cm, it's gonna take 4x as much coolant to fill right? If so, hope I don't have to flush it or top it up too often, cos that would be costly!!

for the coolant get a good quality concentrate coolant basically a 4 or 5 litre fill the overflow bottle first to just under the max mark and use the rest in the rad then top rad up with water should do u well

I use a premix.

Why do you put any water in?
