    Default Radiator heating ?airlock? HELP

    I fitted a new radiator to my veccy 1.9 cdti 120 on sunday as my old one had a crack in it,took it all apart fitted new rad and all went together without a any probs,checked it all for leaks and was fine.filled the system back up cap off,bleed nipple out,heaters full on and so on and left it to run on the drive for about 30 mins and the temp gauge didnt read at all so took it for a quick drive,the temp gauge seemed to go up the faster you go and come down when you slow down,about 3 miles down the road the engine management light came on and the car juddered a bit.got it home and topped the system up a bit and the management light has stayed on since and the temps seem well dodgy.
    has anyone got any ideas?
    thanks

    there are probably 2 bleed nipples - you will probably find another on the rear bulkhead

    Hi M8..this is the procedure for re-filling according to the haynes bible...

    Fill the system by slowly pouring the coolant into expansion tank until it is up to filler neck.

    Using a small screwdriver ,lift up the wire clip securing the left hand heater hose to the heater matrix pipe stub,and disconect the hose from the stub.

    Additionally,on 1.9 ltr engines,open the bleed screw in the coolant pipe above the exhaust manifold.

    As soos as coolant begines to run from the heater matrix,push the sucuring wire clip back into position on the heater hose end fitting ,then push the hose back onto the matrix pipe stub.

    Ensure that the wire clip securly locks the hose in position.

    On 1.9ltr engines,close the coolant pipe bleed screw as soon as coolant emerges.

    Hope this helps.
