In desperate need of advice my 2.0i z4 n46 e85, I recently changed the water pump thermostat housing pulley and mechanical coolant pump and changed the coolant now my lower radiator hose isn't getting hot and my thermostat inside the vehicle is going way past the centre I have tried bleeding it way too many times and I can't get to the bottom of this issue I suspect there's an air lock in the radiator from when I drained it I have tried many methods to bleed it but no joy. This hose I'm pointing at is the culprit the radiator top to bottom also is stone cold and the fan isn't kicking in until the engine is scorching every other hose is really warm. I really am fully out of ideas or what to do if anyone has any idea of the cause of this and how I can fix it or if anyone knows anywhere in South Wales or around abergavenny that can fix this I'd be extremely grateful I'm at my wits end with this I really don't know what else to try all the parts came directly from bmw if anyone would like to get hold of me my telephone number is 07476913299
I also should add that the other hose on the thermostat popped off yesterday and dropped all my fresh coolant rac did the head gasket test as there was a lot of steam coming from the expansion tank but confirmed it was definitely not head gasket I thought maybe the water pump sucked air up through the system as the hose came of and perhaps the steam was hot air? I'm not entirely sure on how the internals work
