My vw Bora. had a water flage problem it was liking I replaced but now it has started raising the temperature what could be the problem. The engine feels very hot you can't even touch the gear box side its very hot
did you blead the air out of the system,check collent leval also.
dont know what engine you have,but i had to replace my thermostat housing,and decided to replace the termostat itself,as the old one was in bad condition. however,after a test drive,the engine became very hot too,and i found that the thermostat didnt open as required(80* C) ? I felt the hoses in the engine compt and the hose from the house to the front radiator was cold as ice= thermostat didnt open. i switched back,since then no problems.. hope it helps
