So. Who decided nissan xtrail would 2 thermostats? One out and one in. And then to attatch 3 hoses and a sensor to some stupid monstrosity to boot.
And tuck the other one behind the exhaust heat shield on the front of the engine? Idiots.
Heater core was clean as a whistle so lack of heat is a terminal ilness or a design flaw.
Cardboard in front of rad will help with the lack of heat.
