How cold is it there and does your engine cool down any while going slow? If it does it may mean you need a hotter thermostat installed, My first thought would be to check the coolant level in the radiator and the coolant reservoir! Hope this helps and Merry Christmas

For the sliding doors you need to clean the contacts, there are 6 or 8 on both sides, just wipe them clean as they are probably covered in oil/grease/grime.

Might be a weak or failing water pump... Does it leak antifreeze or do you have to add antifreeze very often? When the engine gets to operating temperature squeeze the top radiator hose and see if you can feel pressure from the water pump forcing water through it.
