Attempting a DIY coolant flush based on some videos online. Can someone tell me where the drain plug is for the radiator. Is it on passenger or driver side. Aa picture would be greatly appreciated. I searched extensively online and no pics or videos specific to 07 maxima. I got underneath the car and found a plug right above a small hole, (with the shield still on) on the passenger side. Is this the one? Also, I'm reading posts about striping the plug. Any advice on making this fool proof or not making the situation worse.
