Hey guys, my VX Clubsport is not getting up to normal temperature, it will sit way down close to the cold mark all the time when warmed up or driving for ages. it only gets to just below half, which is normal right? when i flog the crap out of it for a while. would it be a thermostat? i have recently replaced heater tap and flushed the system which caused water pump to leak but now it has stopped. any ideas?
