      Will this thermostat housing fit with the Mishimoto Silicone Radiator Hose Kit? My stock 1996 Mustang GT with 4.6L 2V SOHC NA thermostat housing will not allow the Mishimoto Silicone Radiator Hose Kit to fit without kinking the hose. The upper radiator hose and the thermostat housing do not line up properly.

      • Hi, This 90 Degree Thermostat Housing w/O-Ring is a factory direct fit replacement it should not cause any kinking with silicone radiator hoses unless the hoses are too long and need to be trimmed please call or send us a email so we can help you out with your problem.

          Worked as needed. Will need a longer coolant hose than factory as this is at an angle instead of straight out like factory.

          Odd fitment

          I purchased this quite awhile back to complete a complete cooling upgrade for my 02 GT, and while I appreciated the price and consistent delivery I always get from AM, the product itself left a bit to be desired. It didn't fit nearly as well as the stock housing did and left a little more overage around both the bolt holes and the mouth of the housing than what I was comfortable with. All in all I did not end up using it after a few months and just went back to stock housing.

          Thermostat housing.

          I'm master certified in all areas of automotive repair and can say without a doubt this item is worth it; especially if you have the revised PI intake. Bolts right up, no fabrication required.

          good not perfect.

          Housing is just like stock, only gave it a 4 because there were a few ruff edges. I filled them down and polished it up before installing, works like stock one.
