Bought a 56 plate R50 a few weeks ago, all seemed ok till steam started coming from under the bonnet, soon realised the fan wasn't kicking in. Quick google found out what the problem was and by passed the dreaded resistor, guess what, still no fan. So I just changed the thermostat, absolute nightmare couldn't get the battery tray out(bolt heads had corroded). I put the coolant back in that came out and it was way over the max line, so ran the engine till warm, expecting it to fall once the thermostat opened but no, nothing, so must have an air lock. Opened the bleed screws 1 just off the top hose and another on the heater hose, coolant came out of both straight away, still nothing, still way over the max line. Pumped the top hose a few bubbles appeared in the reservoir but nowhere near what you would expect. And worst of all still no [email protected]#&*"g fan. Can anyone please help I'm at a complete loss.
