Hello Years ago the thermostat was always in or near the top hose,,now many are in or near the bottom hose---can you tell me why//???
Anyway the stat on my car was stuck in open position so engine and heater was running very cold
For a qwick temporary fix I put an inline stat in top hose,, this worked perfectly holding engine temp at 85c uphill and down dale
Until I selected cold on drivers side heater control ,,,upon which the engine was boiling in less than a mile
When selecting hot on the heater everything was OK again,,running at 85C
Can any one please explain???

Thank you
 
No replies,so must be a stupid or dificult question

Anyway,today I removed temporary thermostat from top hose and replaced new stat in proper place in bottom hose
Now running nicely at 80 degrees C
