I would genuinely love to help but it's nearly impossible to read what you have written there. Try introducing some punctuation.

 

However, it seems to me that you've got two questions:

 

1) My plastic bleed screw has snapped in the thermostat

 

- Not a problem, just replace it with a screw of the same pitch thread, from memory the bolts that hold the discs in place (front or rear) fit. This is what I did to mine when I made the same mistake as you. I also wrapped it in a bit of teflon tape to ensure that I didn't get any leaks and it's been fine for well over a year now.

 

2) What is the best way to bleed my GTI?

 

- This is a nice easy one, because the GTI is a really easy car to bleed, you don't even really need the lower coolant screw I've found. Simply turn the heater to hot, and turn the fans on. Then fill with coolant mix, and undo the heater matrix coolant bleed screw, just to be sure that there's no air left in the matrix itself.

 

Then, with the cap off the coolant bottle turn the engine on and leave it to idle, at this point it will be cold and will be self bleeding all of the air out of the engine block. By the time the air is blowing hot from the cabin heater the thermostat will have opened and all the air should have been bled out of the radiator. Obviously you should be monitoring the temp gauge and water level the whole time this is happening. Top the car up with water, put on the water bottle cap and go for a long drive, carefully watching the temp gauge for any funny movements.

 

After a bit of a drive I always pull over and check that the water level still looks good, it may drop a bit just bleeding the last few bits of air out of the system.

 

Finally, once the car is cold again I top the water level up if it needs it.
