Okay guys, I have looked it up a bunch but I have found a million different ways to do this. So this is how I was gonna go about it... How does it sound?
1. Open radiator cap
2. Drain radiator via drain plug at bottom of radiator
3. Take off tstat housing and take out tstat
4. Replace radiator cap, keep drain plug open.
5. Using a garden hose with a rag to create seal, place it in the opening in the engine block (where tstat was) and spray until clear water comes out of the radiator drain plug.
6. Put new thermostat in (180* for me) with new gasket and replace housing
7. Close drain plug.
8.Open radiator cap and fill with water. Then close cap
9. Run the car for 30 seconds then drain water via plug.
10. Repeat steps 8 & 9 a few times to ensure clean flush.
11. After final drain, refill radiator with water. Run car until tstat opens and water level drops. Fill radiator to top with green coolant concentrate. Run again and repeat.
12. Bleed system via bleeder screw on housing
