Hello. The AA technician that came out said the water pump is running fine, and other parts are running fine. He put it down to either a hole elsewhere allowing air to come into the system or possible headgasket failure ...
He did a tempreture test on the pipe with a lazer temp checker and it seemed ok he said.
However at this moment is time there is no mayo on engine oil cap, the oil looks fresh. The high tempreture doesnt always show up on the dashboard, it seems like its normal operating temp but engine management light is on and you can feel the heat around the cars emgine bay.
