steps to replace rad
1. Engine cold (only to avoid burns) undo the tap at the bottom of the rad on the offside (drivers) side of the car, this will allow the rad to drain. Collect this in a bucket if you wish to re-use ( or make sure you have some replacement coolant ready)
2. Undo all hoses connecting to radiator
3. Undo 2 mounts at the top of the rad (they also locate the bonnet stay)
4. (I think) the rad just lifts out now?
5. Remove fans and carriers from you rad and transfer to new rad.
6. Install new rad into car (reverse the removal process)
7. Fill coolant system with coolant.
8. Run engine with cap off coolant system, squeeze hoses to encourange the air to get to the header tank, top up as neccesary.
Done
S'netters feel free to correct anything with this ( im just trying to demonstrate the scale of the task) Easy to do really.
Hope this helps
