Hi guys and gals. Firstly a hello from me, just bought a mint astra 1.7td 1995. Very well looked after but it has a problem. I broke down the other day. overheated. the RAC man took out the thermostat and said that should sort it (temporarily) and keep it cool. I have since flushed the radiator. Now the temperature is all over the place. as soon as i hit motorway speeds the temp rises to around 100 degrees. but if i slow down and put the heaters on it falls to below 90. there is no oil in coolant and no gunk on the oil filler cap.
sorry for my first post being a question but if anyone could offer any suggestions I would appreciate it
Thanks in advance
