Cheers Andy, the video is actually very helpful to me. I have a new rad to fit and I was going to give the job to a garage but having looked at this vid I'm sure that I can sort it out myself. One thing you might think of mentioning is that when recharging the rad with coolant it's very important to have the correct level of anti-freeze/anti-corrosion mixture. Otherwise the cylinder-head bolts can corrode and possible cause a massive engine failure. Same if your buying a t25, any water leaks around the cylinder-heads, steer clear. Thanks a lot and best of luck mate, Dave.
