Spark plugs will not cause vehicle to over heat. Over heating is caused by bad thermostat, water pump, clogged radiator or cooling system or anti freeze leak.

And also make sure the fans are coming on.

Yep, had issues with overheating on 300m as well. As firebird said one of the radiator fans was not working. Replaced it and now is fine. If you change it out make sure you bleed the system well. There is a bleeder valve on the top of the block near the front.
