    New water restrictor plate for the Mercury or Ford equipped with the 351 Cleveland engine. It has been an accepted fact for decades now that the 351C bypass system was not the greatest idea Ford ever came up with. The unique 351C thermostat "hat" never seals well, causing a certain portion of coolant to just circulate through the block and never make it to the radiator. Years ago, Pantera enthusiasts (all Panteras had cooling issues from the factory BTW) found that if they soldiered a penny into the hole in their restriction plate and used a standard small block Ford thermostat, their cooling issues all but disappeared. That trick worked fine until Ford discontinued the brass restrictor plate. 

    This aluminum unit is designed to replace the brass plate and be installed as-is. Simply remove the original brass plate and tap this one back in its place. This unit must be used in conjunction with a standard thermostat , you cannot use the 351C unique thermostat with this block off plate. The tiny hole in the center is for air bleed only. Want to find out how to use a penny instead of purchasing this plate? Click hear to learn more!

    On a record hot day in Evansville, In at 108 degrees the car was driven a while. She never went over 200. Im so happy with this upgrade, get the WCCC part and a 160 thermostat and your problems are cured!

    Replaces Ford Part number D0AZ-8K517-A.

    I had to poke around the internet to understand that there is a factory plate, covered in blue paint that disguise that it wasn't a cast part of the engine. It needs to be pried out and this piece replaces it. It was difficult to pry it out, but the replacement piece needed to be tapped in with a punch and fits tightly.

    A few instructions would have been nice. It is really the"right" fix for the problem. I am glad your company came up with the solution.

    Your recommendation to use the water restrictor plate to solve my overheating problem was spot on.
    Ironically the thermostat I took out, which I thought was original turned out to be a Windsor thermostat.

    Thanks again for the solution to my problem,
