Hey guys, I know this has been covered before but cant find a difinitive answer to my problem. My car has started overheating. I replaced thermostat and temp sensor about 8 weeks ago. Car gets to operating temp as normal then creeps up. Hose from the thermostat housing to bottom of radiator stays cold throughout while other hoses get hot. Car is a 2000 1.8T Aum with just over 80k. Could this be a faulty thermostat? Or something worse like the water pump? Is there any test I can perform to check the if the water pump is u/s? Many Thanks, Graham.
