Radiator Recovery Systems

[Buz400]

Hi guys ,

I have 95 R33 GTR and just recently replaced the factory radiator with a Just Jap cooling pro one after the factory one cracked and as soon as I saw coolant coming my vented bonnet I shut it down so it didn't over heat.

Now my problem is that the recovery seems to be only working one way and not returning to the radiator.

Any suggestions??

I have had it pressure tested heater core etc are not leaking it doesn't get hot at all just a pain in the rear to keep topping up.

Many thanks

Radiator cap? I have had so many faulty ones lately.

Easiest to try the rad cap first.

Is it pushing out, but not drawing back?

Is the radiator neck welded all the way round, or does it looked pressed in?

I had an issue with my china radiator where I thought I'd lifted the head because I was alway pushing coolant. But what was happening was the coolant would push out under pressure, and the neck would allow air in to the rad on vacuum. Got a new neck welded properly on the rad and bingo, problem fixed.

Thanks guys, yes not drawing back , but held pressure for at least 30min when pressure tested .

I'll buy a new cap and see.
