Gidday there Bill.
Having just come out a rather hard Winter here, I'm glad that I had the chance to do a really good service on my Faults truck (which is a Toyota Hilux SWB ute).
Before the weather got too cold here, I spent a whole day giving the truck an oil change, replaced the Fuel filter, checked the Belts and Timing Chain.
I flushed the Coolant system and recharged it with new water and Anti-Freeze.
I then checked the AirCon system and ran it for an hour and checked the HP/LP pressures.
I Load tested the Battery and replaced it as it was found to be wanting in CCA, as I have a Winch on the front of this truck.
The Alternator was also tested.
As far as my house goes, I just checked the Air Conditioning pressures and the Compressor currents and all seemed to be fine.
All that was left to do was to get my BIG pot of Winter soup started on the stove and get the bread baking in the oven!.
