yeah thats it the bottom 1 is rock hard ill jack it up in a bit and take it off and have a look ill let you know if it work
thanks for your help

theres 2 pipes for the matrix, just take them both off, easier from underneath.

yeah it aint an air lock though i have done this a few times now and it still aint getting hot though and theres a water pipe that goes through the bulk head and its hard as a rock and the 1 above it can be squeezed a bit if u know what i mean. so would i have to take the pipe off to flush it? cos its a bit of a pig to get to

1. get engine up to about 95 degrees
2. remove cap from expansion tank
3. put blowers on hot on setting 2
4. run on fast idle (2000rpm) until coolant bubbles over from expansion tank
5. let it bubble over for 5-10 seconds
6. turn off engine and blowers
7. leave to cool down completely
8. top up expansion tank

that will get any airlocks out.

i had to shoot a hosepipe through my system to blast the gunk out


did u have to locate the cloged pipe and remove it or just done it through the water resevoir?

you need to bleed the system, there should be a wee valve on one of the pipes. Not too sure on how to do it in a corsa.

hi ya my heater inside the corsa aint getting hot. i think 1 of the pipes is bloked with rad weld or something as i had to change the rad as it was fluffed. how would i be able to flush it out? any suggestions?

thanks
