International Lancia Forums

Hello.
I wonder what is in and out of the heating radiator (inside cupe) on my Lancia Thesis 2.4 JTD 2003. I will mount a hose heater with an integrated circulationpump, and it need to be installed on the return line from the heating radiator. Is there any drawing showing the tube out, or what is the direction of the coolant flow?
I know that models with Webasto parking heater, it is connected on the right tube in the torpedo wall. But the water flow direction does not know .... What is in or out?
You can help me?

best regards

I found it out. The coolant flow is clockwise. The right side connection is in and left connection is return out.

Hi!

I installed heater with pump about a month ago. I think that thermostat box is a bit different on diesel than on 3.0 V6, but here is just a photo of my connections.

Lower one comes from heater core (I added some new hose) and is connected to inlet side of pump. Upper one with 90° elbow is connected to outlet side of pump.

Exactly as I told you at the beginning
