    Worthless

    2 of 2 people found this helpful

    I installed this in a 1999 Taurus with a 3.0 OHV engine. After initially warming up quickly, the temperature suddenly dropped. It rose again, then, once again dropped dramatically. This cycle continued as long as I drove the car. It must be noted that the engine never achieved normal operating temperature, and a check with a scan tool showed that the temperature just barely surpassed the rated opening temp before falling.

    I took this unit back to AutoZone for a warranty replacement (and another gasket). The second one behaved just like the first one.

    A third, name brand superstat (and a third gasket) solved the fluctuation/low temperature problem.

    I will not purchase another Duralast thermostat again. It's money wasted.

    Pros: Stainless steel construction

    Cons: Does not maintain anything like a constant temperature

    No rubber rim gasket.

    2 of 3 people found this helpful

    Went to change the thermostat, after draining the fluid, I took off the old thermostat, bad surprise, the thermostat is supposed to have a rubber rim gasket. I had ordered the paper gasket (pn 35062) but you also need the rubber rim gasket (pn 35710).Hope the old gasket seals.
    1992 Chevy C2500 with 350 engine.

    Pros: Not sure,

    Cons: No Rubber rim gasket
