Fluid resevours

[ezza]

I need to establish a couple of things for my build, im trying to keep the engine bay as empty as possible so im planning on hiding things out of sight.

anyway...

The power steering reseviour;
Does this have to be at a certain height in relation to the pump or can it go anywhere? also could i use a generic alloy catch can instead?

the radiator overflow;
Again does this have to be at a certain height relative to the rad? also what capacity does it have to be roughly does anyone know?

thanks in advance

Normally the power steering reservoir should be higher than the pump as it's gravity fed.... if you want to get fancy you could pump it into the pump lol

As for the rad overflow, it really shouldn't matter because it's pressure fed

thanks

what do you mean pump into the pump though?

I was thinking of using this upside down, reckon it would be ok?

what i mean is that the fluid has to get into the Power Steering Pump somehow, so if you install the Reseviour somewhere lower than the pump, it's going to have a hard time getting into the pump.

Therefore, if you were dead set against putting the reseviour in your engine bay, higher than the PS pump, you'd have to put an electric pump in line with it and pump the fluid into the pump... but that would just be silly

yeah PS res. needs to be higher than pump or system will drain if you remove cap to fill also...and as was pointed out it isn't self priming so it need gravity feed.

I would think the return would have to be relocated to the top on that reservoir.

I had to do something similar because of tubs. I got a reservoir from ebay, and had it cut to fit. It will be placed in the corner by the brake and clutch masters. Since you are from the UK, that area will not have the master cylinders, so you should have no trouble fitting something in there.

I think il not put an electric pump in haha

Yeah since I tubbed my arches I can't put it back where it was and I want it to look nice too, I may have to chop a catch can up like you have^

Doesnt anywhere sell billet/alloy/polished pas res's?

Chase Bay's does. They've also learned, the hard way, about how the returning ATF comes back to the reservoir with some intensity. You'll need to internally baffle the reservoir. Check out the stock reservoir, it doesn't need to come back into the top, it needs to be slowed down and have room to de-aerate. I would definitely mount it higher than the pump, starving the pump will kill it. I'm not confident that clear tubing and push-lock fittings on that catch tank can handle the heat.

Here is the Chase Bay's one I have but I've added a bracket to it b/c I don't like the "clamp on" style it came with. I'm also tubed.




The coolant overflow isn't under pressure, as it vents to atmosphere, but it needs to have a bottom pick up since it draws liquid into the system as well as provides an overflow out.
