    My Low Coolant Light is on. I've verified it's not low, bled the system (let the air out) and it's still on. The next thing I will try is replacing the sensor. My question is does anyone have a recommendation on what brand to get? Should I just stick with an OEM product?

    First step is to clean it. Not replace.

    New situation, The low coolant light is on again and this time I'm leaking coolant. As best as I can tell it's leaking from the heater water inlet pipe. On the lower intake manifold side. I'm wondering if anyone has a wright up on this or may know the easiest way to replace it.

    Any and all help/suggestions are appreciated.

    Thanks

    Thank you for the link. My biggest problem was having no clue what to search for. I got the (heater water inlet pipe) part description from alldatadiy but found nothing that was helping me piece it together.

    Again thanks for the link.

    If you go to your local autoparts store with that part number they'll have what you need.

    You can unplug the sensor and the light will go out.

    I've installed the 2 coolant elbows, filled the fluid, bled the system and all is well with one exception. The soft rubber T shaped vacuum piece right above the upper elbow broke. That appears to be a part neither Advance Auto nor NAPA carries.

    Does anyone know where that can be purchased? or is it a trip to a junkyard/dealer for me?

    what you need is a plastic T, advanced has them, they are small and white, come 2 per pack for 2 bucks, then get 3 inches of vac line.

    cut the old lines off the stock line on both sides of the snout T, then cut your vac line into 3, 1 inch pieces, put one on each line, and the snout, then put the T in the vac lines.

    If the lights on and the coolant is full the sensor is most likely bad. They go bad all the time. Simplest fix is to unplug it to turn off the light. Or buy a new one.
    No More GTP for me.
