2.5T Coolant Change

Post by xcinla »

Hi, I'm planning on changing the coolant on my 04 2.5T XC90 but can't find any info clarifying where the petcock is or the procedure itself. I recently had to top off with the green stuff when I found coolant low and want to change out completely now that I have the pentosin (blue stuff).

Any info is appreciate.

I just recently did this. All I did was removed the lower hose and drained, reinstalled hose. Put in distilled water, ran engine until thermostat opens. Pulled hose again and drained. Refilled with distilled water, ran again, kept performing until water being drained was was clear. Bought Volvo Engine Coolant, mixed 50/50 with distilled water and refilled with the mixture, had to top off twice after the system burped itself. It has been 500 miles now and temp is fine and level hasn't changed.
