Had a great day without getting stuck anywhere but suffered a few scars.
On the way home the engine was noisy, possibly a pully. Maybe power steering pump as the power steering seemed to go off a few times during the afternoon.
There was a grinding noise on the way home, maybe brakes or propshaft
Then it overheated and lost power coming into Braintree, had no heaters all the way home.
Topped up with 2ltrs of Tescos own water for 17p but no heaters.
I'm hoping its just an airlock and will replace the water with antifreeze in the week and top it up through the thermostat housing.
Might even get a new stat in there.
