  1. The thermostat housing looks quite common to most other older engines you may find something in a very similar size form Chevy or Ford at first glance.

    The water pump may work like the union next to the corroded one by chopping off the outlet pip and threading the body to accept a steel pipe to connect to. Its worth a try before binning of the assembly if the rest of it is in good condition

  2. Most cars will perform better on highway as running at a constant speed.

    Around town the figure will most definitely drop but enhance slightly by the hybrid assist if enough regeneration occurs on stopping and on overrun

    Those figures don't seem too unreasonable at all

  3. I would look at the above post as it mentions replacing the vehicle battery which if discharged will give these symptoms.

    Additionally, the vehicle may need to be programmed to accept the new battery voltage, otherwise it will still read the discharged voltage reading

    A breakdown/recovery service should be able to get you up and running if the vehicle is immobile

  4. That's a tough one! 

    you seem to be checking everything in the correct order and the only other items I would check is the integrity of the catalytic converter joints (the slightest air leak can cause issues with lambda readings)
    An emissions gas check can highlight any air leaks by way of high oxygen content (should be zero at the end of the exhaust).

    Otherwise, you could replace the oxygen sensor connections or even hardwire them to ensure no error with the connection terminals?
