Gen6 cooling flush
From Wiki
Cooling System Flush: (Approx:- 7 Ltrs)
- Remove the under engine cover then pull off the bottom radiator hose.
- Remove the thermostat then put the housing back on without the thermostat.
- Remove the top rad hose at the rad end.
- Switch on the ignition, turn the heater control to full hot then switch off the ignition.
- Stick a garden hose in the top rad hose removed earlier using a cloth to make a bit of a seal then let rip with the water until what runs out the bottom hose looks nice and clean.
- Use the same method to flush the rad through, sticking the hose in the top pipe outlet.
- Once everything is flushed out stick the old, or preferably new thermostat back in and re attach all the hoses.
- Fill up slowly until you can't get any more in using fresh coolant.
- Once full, leave the cap off and start the engine.
- The level will likely drop straight away so add more and keep doing so until any trapped air is out.
- Once its settled, stick the cap back on and let the engine come up to full temperature, making sure its not overheating.
- Then switch off and let the car fully cool down again before doing a final check on the level.
