Problem DK35 overheating, changed fan belt, new thermostat. When releasing pressure cap, fluid flows into resinous but not when cap is on. Will get a new cap this week but this one is only a couple years old. Any other ideas??

The reservoir is supposed to catch excess fluid as it heats and expands then allow it to go back to the radiator when it cools. I'd try blowing air then running water through the radiator fins from back to front. You may have dust and weeds built up preventing the transfer of heat.

What symptoms of overheating are you seeing. Guages sometime malfunction but if you are saying steam comes from cap when in operation, that doesn't sound good. Might want to try a thermal thermometer or new sending unit. Be very cautious to not overheat more than absolutely necessary for troubleshooting. Diesel engine doesn't tolerate overheating and can be easily destroyed. Blown head gasket is a suspect and usually causes bubbles in radiator when turning engine with starter and idling. Some auto supply stores offer chemical that changes color if exhust gases are present in coolant.
