When I replaced my thermostat a little while back, I simply took off the top pipe, waited for enough water to drain out, did the job and then refilled into the expansion tank until it was back up to normal level. Was this a really stupid thing to do? Could that be why when I do 70 for a while it goes slightly above the middle mark? Is there a correct way to "purge" the cooling system, or should I drain it all out and start again?
Thanks
