A cracked radiator hose, a thermostat that sticks in the open position or leakage around the connecting pipes are classic signs that the cooling system on a 240 with the B230 engine has begun to age. Rubber dries out, clamps lose their tension and small leaks lead to dropping temperature or overheating depending on what is acting up.

This category includes thermostats, radiators, radiator hoses and other hoses, gaskets, connecting pipes, hose clamps and plugs – in other words the parts around the engine's fluid flow and temperature regulation. The selection is gathered for the four-cylinder B200 and B230, so that hose and connection dimensions match the engine bay in the 240.
A typical inspection point during a rebuild is the thermostat itself: when you replace it, take the opportunity to renew the gasket and check over the hoses and clamps that are being removed anyway. That way you avoid another stoppage when an old length of hose cracks the week after.
