Aloha -

Many 240s, maybe others too, come from Sweden with the temperature slide control connected to the water valve in such a way that a little hot coolant flows even though the control is in full cold position.

That prevents the coolant sitting in the heater core from getting stagnant.
But in climates warmer than Sweden it really makes a big difference.

Remove the kick panel by the driver's right toe. Watch how the water valve moves as you move the slide control. What I have done on every 240 I've owned is to re-connect the control wire to the valve lever. There may be an easier way than that. What you want to have is the valve fully closed when the slide control has maybe 1/8 inch yet to go to be in full cold position.

Good Luck,

Bob
