[Mgs] Sleeved Thermostats

[Paul Hunt]

Sticking my head in the lions den here but the thermostat doesn't actually
control maximum or minimum temperature.  It maintains a *given* temperature,
plus a bit of hysteresis, between certain upper and lower limits that are
dependant on external factors.  If driven in very low temperatures the coolant
may not get hot enough to even start opening the thermostat due to surface
cooling and heater use.  Conversely if the engine is generating more heat than
the radiator can dissipate either due to one or more of loading, high ambient
temperature or defects in the cooling system then the coolant temperature will
keep rising after the stat is fully open.
