Hi guys, I'm having issues with the cooling of the 4age which I've installed in my mini. The cooling system is pretty standard except the rad is from a Nissan Micra. Now before you all shout 'fit a bigger rad' hear me out:
When driving on a flat dual carriage way at up to 3500ish rpm, its fine. Up hills it will start getting warm. If I sit at 3500-5500ish rpm, it gets almost to the red. Over 5500rpm, it cools down a bit but is still near the red. If I sit at 5500rpm with it near the red and floor it, the needle actually drops as if its had a shot of cool water through the engine.
I'm wondering if the cool water in the rad isn't getting circulated very well? Can anyone help with this? I need to get it sorted as I've got a DTA ecu and ITB's waiting to be fitted, but there's no point if I can't keep it cool
