CHEVROLET VENTURE RADIATOR PROBLEM

2001 Chevrolet Venture • 253,700 miles

Just bought van with knowledge of the thermostat needing replaced. Bought from the 2nd owner since 80,000 miles. Now has 253700. My issues are is that I replaced thermostat drove fine with barely hot heat for about 300 miles. Now temp gauge jumps hot to cold, also have had it flushed and a new coolant sensor. Drove fine for 50-60 miles and now temp gauge is either extremly high or really low. Mild warm heat, drives awesome still. Getting frustrated.

Get the radiator cleaned by a radiator repair shop.

Would that cause my temp gauge to bounce around? Im not losing any antifreeze as in intake or a head gasket problem. Would a water pump have any effects?

Radiators will cause temp gauges to pendulum.
