Pretty hard to read that lol.

But it sounds like you haven't bled it properly so have a airlock somewhere.

Also the RADWELD / K-stop etc is shit - so wouldn't use that again :P

To fill / bleed you should -

Cut bottom off a 2 litre bottle
get a bucket / watering can full of water
open the 3 bleed valves
Place hand over the lid of the cut bottle and fill with water
Put the cut 2 litre bottle in the rad
Keep filling it with the watering can / bucket (so there is always water in the cut bottle)
Wait until water comes out of all 3 bleed valves - let it run through for 5-10 secs
Close valves
top up with anti freeze

This makes sure no air can get into the system - as it's always water whats going into the tank - no air.

Simple job but easy to get wrong.

:y:

The K-seal that you used will eventually bung your heater matrix up,so as above to a good idea mate.

[PICKLEBASHER]

how do you bypass the heater matrix because im pretty sure its nackard anyway ??? and i did above but i need to geta new valve thing as i threaded it no biggy, i did it as said and it sits tick over fine but when it comes to driving it goes crazy ?

[andyyy]

it will tick over fine as its not under anyload ...

if you want a quick dirty fix just to make it drivable turn the heating up full as you drive around and open your windows

having the heating on take heat from the engine and puts it in the car ...
