my temperature gauge isnt working properly, the needle just goes on red after 10mins of driving it, it hasnt over heated once though, i have replaced the thermostat and checked for blockages, there isnt any. i have realised that when the car has been driven and the needle is on red, the bottom raditor pipe isnt getting hot but the top one is, so the top half of the engine is getting very hot but the bottom part is freezing cold.
Does anyone have any ideas what it could be?

does the bottom hose get hot at all say after a long journey? the bottom hose takes the cold/warm water back through engine the top hose supplies the radiator with hot water so the radiator can cool it. as for the temp gauge goes to hot after short time of driving has the temp sensor been replaced recently? (is correct one fitted?) if not then it could be faulty
