Autocheck water temperature warning?
I pulled the 90 out of the garage this morning to give it a short run up to temperature as I do every so often to keep things from seizing as it spends so much time locked up in the garage.
So very shortly after starting the car, the Auto check comes on coolant warning..........
Of course I turned the car off straight away. out and checked, coolant bottle full to max line.
Water pipes as warm as one would expect for only running a few minutes.
My first thought one of those damn sensors I replaced earlier in the year has quit.
So I restart the car run it up to temp, all the while the Autocheck beeping, but temp gauge reacting as normal, fan comes on as normal.
I open the bonnet again, water pipes are hot and rock hard, yet expansion tank was still cool.
Waited a while for everything to cool down, opened expansion tank and to let the pressure out (squeezed the water pipes, all hot) and bubbled some of the coolant out of said tank.
Thinking I maybe had an airlock, although don't know how that could have happened as it has been fine up until now?
Got under the car and the water pipe that goes to the bottom of the radiator is still cool.
Anyone got any Ideas?
For those that don't know my car It IS a 1990 90 2.3NG.
Just to add to that getting hot air through blowers.
TIA
