not sure if this has been covered'had quick look achives. customer complaining of heater going cold & temp' gauge going up & coolant leak.customer put a rad weld in hoping to cure leak. On first inspection coolant was low,and not alot of ciculation,we had fitted a new water pump last march,so confident that is ok,so decided to fit a new thermostat,whist that was out we checked water pump impellors,ok.put it back together,topped up a/freeze,road tested,all ok,heater lovely & hot,temp gauge in middle. my techy gave it another road test a bit later & gave it abit more stick,heater went cold,temp gauge high & coolant in expansion bottle had risen,also quite a lot of pressure in the system. trying to decide if head needs to come off. any out there come across this. many thanks john.
