is there any one that is running a sealed cooling system? been talking about the cooling system with a few people and no one and the general conclushion is that vw were paranoid about any water loss with the wbx at least, dont know about the heavy oil burners, hence the catch tank and the darlic cap, on moder cars the expanshion tank is only half full at the max level, with the rest of the space in the tank for when the water gets hot and expands (with in the tank).
i have been looking in the scrappy today at mk4 golf passats ect at the round sealed fish bowl type and they sceam to fit the bill to the engine convershion that i will be doing soon, as the cooling system on the new engine is very simple, ie from the pump to the rad, and then to the thermostat input, with an out let from the block to the heater. could use the t3 one with the catch tank, any one got any thoughts.

Re: expanshion and catch tanks
Just got one of fleabay for my van.
Looks big when you put it in the engine bay, not much room with the V8 in there
As I'm raising the floor it should work out OK and will connect up to the coolant level warning light as well.

Re: expanshion and catch tanks
Forget the "norm"
the T25 cooling system uses the "top up" tank as its expansion point..
In a "modern" (read as "normal") vehicle there isnt the amount of rubber hoses to absorb the pressure.. both my "DG's" barely create enough pressure to bleed the rad unless its hot and been worked hard...
In my scoob, perhaps 3 4 or foot of rubber hose.. in the T25.. ooh... 9+ the heater hoses at 14 each way.... dont forget that a modern vehicle holds 6L of coolant if you are lucky.. the T25 is 17L+...
