    51112 is rated 4.9 out of 5 by 22.
    Rated 5 out of 5 by from Successful install first time Since o ring crush is minimal, it's important to have flange and neck sit flat and flush. Burr on the inside of the flange where it holds the neck could have loaded the neck unevenly. I sanded it off and lubricated both parts where they make contact. I also put a small head of silicone on the edge of the neck just outside of the o ring. I did not rotate the neck once tightened. No leaks on Edelbrock manifold.

    Rated 5 out of 5 by from Sweet Piece! Very impressive product for a very good price. Replaced my radiator with a non-OEM model and needed the ability to readjust the upper hose installation. This adjustable thermostat housing worked perfectly and was not ridiculously expensive like some are. Not sure how the other guys are justifying the cost for theirs as this is a pretty nice looking and working alternative.

    Rated 4 out of 5 by from Nice part for the money Looks good, but the finish is not as shinny as i would have liked. But for the price it looks descent. Can't say if the o-ring seals yet....still in the process of finishing the engine.
