93 Telstar AX 2 Litre Thermostat Location

[dirty hands]

bathurst ..yes lets see volvos roll over

I see where the confusion is ..got me confused

y to the bottom w to the top

as mazda engineers see it that location works - for an east west motor -

just not sure why , Mazda

15-270 pipe is the thermostat bypass

my thoughts
1#the whole water flow is stopped inside the block till the thermostat opens
2#if I read the exploded view correctly that thermostat spring is to the block-- behind the water pump

I forget this bit
3#water flow and direction theory in a closed pressurised system

hot to cool physics in a radiator
