hey all

 

after some help.

 

i have fitted a legacy radiator to my leone, which will hopefully help with the temp problems I have occasionally in stages (esp. the tighter ones). now, what I don't know how to do, is to plumb in the header tank, as the radiator has no cap to fill it. has any one done this, and if so, can you explain, prefer with pics, but words will do.

 

as far as I can see, on a std legact turbo, it flows back into the water/aire intercooler, and then through the system, so with the leone, I was thinking of running it backing to the heater inlet, and plugging off the heater outlet hose that goes to the heater...does that make sense?

 

all suggestions welcome...and required.

Put a recovery tank on the side wall. Should work.

You will prolly have to modify your support panel. A few people have been talking about it on Ausubaru.com. That was the general consensis.

The idea here is to add a rad fill port (i.e rad. cap) plus a bit more coolant volume.

The heater hose is not a bad idea (the one running under the intake is the return hose to the H20 pump)

I don't know how many Jaguar XJ 6 Series III s there are in boneyards over there, but they have an excellent tank/cap/hose set up. Which would fit nicely on the inner fender behind the battery.

Hope this helps.

I guess I'm wondering why you choose a Legacy Turbo radiator, the N/A Legacy has a radiator cap. But I do suspect that if you looked at it long enough that one could figure out how to install the tank (filler, not overflow) as it is on the Legacy. I have gone the other way, and installed a Legacy Turbo engine into a RX and used the RX radiator, after some slight modification to the angle of the input and output tubes. I'm kind of surprized that the Legacy radiator even fits, but it appears that you have made it work, good job.

 

By the way, the air/water IC on the Legacys have a separate water system, it does not use that engine cooling system. The water reservoir is the tank on top of the I/C, the system has it's own pump and radiator.

great, thanks for your help all.

 

the legacy turbo radiator is bigger, and has better flow, which is why I chose it, and to get it to fit isn't too hard., just have to modify the front vallance a bit...and hey presto...much better cooling...which equals a faster rally rx, well I hope so, won't know until the engine build is finished, and th ecar runs it's first shake down test in mid february.
