Rubber O-rings for Heater Matrix

Hello all, I just found out that my heater matrix is leaking coolant on my carpet when temperature is below 0 ( Celsius ). I pulled apart plastic housing that heater matrix sits on top of and found that coolant is going pass the pipe joints.

i'm thinking there are rubber O-rings in that pipe that can be changed but I can't find the right part online to order. Can you post a link from amazon or e-bay for those O-rings and if you can, write me your experience when dealing with heater matrix leak.

Thank you.

After changing the coolant and rubber O rings for the heater matrix, when heater fan is turned on, engine coolant temparature is getting lower.


Anyone knows what might be the cause?

I don't think that is abnormal at such a low outside temperature. You actually try to cooling down the coolant to increase the interior temperature and it dropped only a few degrees.

positive I only recorded it for a few minutes, temperature gets below 80 degrees when heating fan is turned on. Before the coolant change, engine temperature would reach 90 degrees pretty easily and it would stay there no matter what outside temp is nor if heater is on. Is there maybe a temp. sensor or something inside of a cabin next to heater matrix that could disrupt engine temperature?

Try to validate the coolant temperature with an OBD2 tool and check it again in a warmer outside temperature. I have no other idea.
