This is also time to install new injector seals. Check for a coolant airlock via "coolant line valve, (same size as a tire valve)" after evac. , otherwise chance heat damage to heads . Use engine oil flush, siliconed areas have to be clean. Do a second oilchange a week later, three years later, change out your expired acidic gasket eating coolant .
