I have a DeWitts aluminum radiator in my Beaumont. It didn't come with a DeWitts cap.

Mine did but that's not the point.

The DeWiits cap is pricey, but I’d first check to see if your system is pressurized correctly (Be careful man…). I was pretty frustrated with mine in traffic until I resolved it. By the way, I can now watch the temp change as the thermostat opens. That wasn’t possible before. It would just keep climbing until the traffic cleared up (or I shut the thing off). I’m currently using a 180 Stewart Thermostat, but I’d like to try a 160 example (I have a similar drilled Stewart on order).
