Hello,
The 200 is overheating just driving down the road. The thermostat was changed recently. Checked the oil and no water in the oil.

Any ideas?

Thanks:
Justin

Was it overheating before the thermostat change? Could be possible it got put in upside down. The spring goes towards the engine. Hope its something simple like that.

Radiator full?
Water pump belt tight?
Radiator fins clean?
Thermostat good?
Radiator flushed good?
Pump good?

Are the belts running to the bottom of fan pulley?

Does it cool down at idle? MACK

Is the radiator pluged up. Our 200 was doing weird stuff getting hot. One part of the radiator was cold and the other was hot. We took the bottom hose off and back flushed it bunch of times. Took thermostat out flushed out through that way to. Seems to be ok now. Have to put thermostat back in still tho.

What about the outside fins of the radiator? It doesn't take much crap to fill up the cooling fins and restrict air flow through.
