Coolant problem with Vauxhall Vectra
I have a problem with my 2005 Vauxhall Vectra C 1.9 diesel, which dumps the coolant out of the overflow tank every time I drive it. Also the temp gauge never leaves zero.
I have changed the filler cap and it has not helped. The only place I can see the coolant leaking is on the tank. Could it be that the thermostat has failed in the closed position?

You've got an airlock. Could be a problem with the thermostat. But if just an airlock you can probably purge it yourself by running to temperature with the expansion tank pressure cap off.

Far better than previous Vectra. Now with decent handling and an excellent ride. Plenty of safety kit. Roomy in the front. Big boot. Good looks.
