I intend on flushing the coolant system soon.
Other that the standard empty it out, flush with water, fill back up with proper coolant mix. Is there any special points I need to check or bleeding bolts to remove air bubbles?
Cheers Tom

| The best place to start would probably be to remove your thermostat and replace housing. Remove top and bottom radiator hoses and open heater tap to full. I am not sure about where the bleed screws for filling are on the series ones but the series 2's have the screw on the top of the thermostat housing. Someone with a series one may be able to shed some light on that matter for you. Hope some of this makes sense to you. Not in the best frame of mind for this at the moment. |
What's the difference between understeer and oversteer?
Understeer is when the driver is scared.
Oversteer is when the passenger is scared. |

| I have just found some info for you. They reckon you loosen the top radiator hose to allow the air to escape. You can also use the top radiator hose as your fill point. Hope that helps out a little bit. They also recommend a coolent mixture by the name of Tectaloy VPlus +. |

Yep, I did my entire cooling system only a couple of months ago, after a hose split.
The easiest way to get the thermostat out is to remove the throttle body and t/b to manifold elbow, undo the bolt holding the thermostat housing in place. Get a piece of wood about half a meter long (soft wood is good, hard wood would do if it's all you've got), and a hammer. Remove the hose from the thermostat cover, and using the piece of wood, start beating crap out of it with the hammer. All you'll need to do is get it loosened, after that you should be able to twist it out by hand.
I'm going to do a full how-to on the S1 cooling system soon.
In short though, to do a flush/refill...
1. Disconnect hose from thermostat housing
2. Remove thermostat housing.
3. Disconnect top radiator hose from radiator
4. Disconnect bottom radiator hose from radiator
5. Remove radiator (this just makes it SO much easier to flush the radiator and block).
6. Remove thermostat
7. Reverse Flush using hose jammed in bottom radiator hose
8. Forward Flush with hose shoved in thermostat hole
9. Flush radiator
10. Re install radiator and thermostat, hook up all the hoses.
11. Disconnect the water pump bypass hose from the front of the manifold and the overflow hose from the radiator
12. Loosen the hose clamp holding the hose to the thermostat housing (do not remove hose)
13. With a BLUNT nosed screw-driver, gently insert the screw-driver between the hose and the housing so as to allow air to escape.
14. Slowly fill the coolant tank with coolant until coolant starts to leak from the radiator overflow connection and from the waterpump bypass hose.
15. Reconnec the overflow hose and the bypass hose
16. Continue filling slowly until coolant starts to leak from where the screwdriver is jammed into the hose. Remove the screwdriver and secure the hose clamp.
17. Continue filling the coolant tank until it reaches the required level, crush and mix in three cooling system pellets (available from holden)
18. Start and run the engine for 20 minutes (with the cap off the coolant tank), to purge any air from the system, top up coolant level as required.
19. Allow to cool and check level.
Hope that helps, a full how-to should be posted sometime in the coming weeks. |

Clearly you've never seen one of my how-to guides. They tend to come with pictures, measurements and almost fool-proof instructions. LOL.
Check out the how-to section, you'll see what I'm talking about. Cleaning the throttle body is easy enough right...see how long the fool-proof writeup is  |

I have seen the how-to section and it is great. It's a great idea and (IMO) this would be a good topic to have in there.
How are you coming along with the 'how to program your own memcal' going. |
