    Default ANother coolant leak

    Greetings All,

    I had the upper coolant elbows replaced last summer. I am now getting the 'low coolant' light come on again! Any suggestion as to where the second leak could be coming from? Are there another set of plastic elbows that could be bad? No puddles under the car.

    Thanks in advance for any help! 2002 3.8 V8 no turbo.

    Scott

    your engine could be eating the coolant, via bad intake and upper intake gaskets going bad.

    What does the oil look like? Any moisture under the oil fill cap?

    Is it even low or is the light just on? Could be a bad sensor.

    Thanks everyone,

    The car has 95K, no water under the cap, water is low. I guess I could change out the sensor, just looking for ideas.

    Thanks much!

    If your coolant is low and there are no external leaks then you probably have leaking LIM gaskets, or a failing UIM. Need to get this taken care of ASAP before you spin a bearing and toast the motor. Search for LIM gasket replacement on here. It's been covered 11 billionity times.
