Re: 03 Navigator coolant question
i think gm is the only one who uses orange coolant??
I used a hydrometer to suck out the coolant to check out the color cuz looking through the jug is just wrong. I sucked some coolant out and it looks yellow. One problem. I do not know if it is actually yellow, or if it was green and the green turns yellow when the coolant is bad/needs to be replaced and flushed. My best bet, i believe, is go to the dealers and give them my vin number and my production date so they know the right color. I think its green because the coolant never got replaced and it is 100,000 k miles. Also, it smells too
