I know my vehicles really well as I do all the services and repairs. While I knew I pin-point diagnosed the recent engine failed to turn over, there is something in the mind that something can still go wrong. Taking a 6 hours round trip into town is not something to be taken willy nilly. A few months ago I notice there had been slight loss of engine coolant. I did visually witness some wetness on the ground immediate below the water pump, and I replenished the small amount of coolant lost.
