    Coolant Supply Line

    Is the coolant supply line located by the right passenger side tire?, I took off my tire because I had to find a leak and it seem's like there's a metal tubing and rubber tubing connected together and my metal part is leaking, I'll have picture's to show alot better but is there a way to fix this.

    Did you take a picture yet? I have coolant going somewhere and found some on the passenger tire and on the wheel well, sounds like it maybe the same leak that you have. I hope that's all it is, losing about a 1/4 gallon of coolant a week. TIA!!

    There are 2 metal heater pipes that run along the back of the motor. Hell to change. Check the all the clamps on hoses running to and from the heater core.

    If you do need to change the heater pipes, they are a dealer only item.
