can anyone help?

engines been overheating alot...its ok when sitting idle but when driven it gets way 2 hot....the top radiator hose gets hot and the bottom one stays cold? so far the waterpump, thermostat and radiator thermo coupling have been replaced but still my engine overheats and the same as before, top hose roasting and bottom cold

have you changed the temp sensor too?

[kyle_mk3]

would tht cause it 2 overheat?

Not normally. It would make the idle rough, fuel consumption high, and the temp gauge wouldnt work properly

Take the radiator out and lift it up. If its light its fine, if its heavy its blocked.

cool, ill get back 2 u adter i have done that. would a blocked one call 4 a new one? been quoted 40 quid for one new

Well, you can get like a rad flush fluid for it, but for that price id just replace it - old ones get gunked up over time anyhow.
