Well I got a short question. Cannot find the cockpit on this radiator. How can I drain this radiator? The car listed above is the Luxury model.

Hello,

You can't find the radiator petcock because there isn't one for this particular model. You drain the cooling system with the lower radiator hose. In the diagrams down below I have included the procedures for draining and filling the cooling system from the vehicle manufacturer for your vehicle. Please go through them and let us know how everything turns out. I hope this helps.

Thanks,
Alex
