how to change/replace radiator

Hi

Does anyone have instructions on how to change/replace the radiator on my Mk1 Golf 1981 1.3, ive got same rad that has the top filler kneck inbuilt.  

Thanks

dead easy job. get a large container under the rad and undo the lower hose. let it drain fully, then undo the top hose and the 2 brackets holdign it onto the slam panel.

next unplug the loom from the radiator fan and thermoswitch on the rad, and remove it from the car. if you need more room you can unbolt the fan shroud from the rad its only 4 bolts but it'll probably be ok.  if your car still has them there may be some cardboard air guides, unbolt those if need be but they're probably long gone.

if your coolant is all dirty and brown, undo the hoses from the side flange and the hoses to the heater matrix (pies that go to the bulkhead) set your heater to hot. push a hosepipe in all the open holes and blast thru till the water runs out clear from everywhere. reconnect hoses, swap the new rad over the reverse of how the old one came out.

If the bottles of coolant you bought are not pre-mixed, empty 1 bottle into the tank, top bottle with plain water (or deionised battery water if you wanna be posh!) and tip that in. pour the 2nd bottle of coolant into the 1st up to half way, then top both up with water. then fill system as required. 50/50 antifreeze mix the easy way

finally bleed and check the system as per:

It is easy to get an air lock in the coolant system with a top fill rad once you refill it, the way I get around it is 1/2 fill the radiator with the top hose still off then fill up the engine with coolant from the radiator top hose till it starts to come back out the hose the put it back onto the radiator the fill the radiator to the top  line the run with cap off as per guide posted on this thread.

If you have an air lock the engine will heat up quickly and not all the hoses will get hot and the heater will only blow cold air.
