Appreciate the help guys. Here's what happened next. I couldnt get the jack under the front of the car due to the low splitter so I decided on the jack up the rear of the car and then get the axel stands under the front approach. This worked great, so I was under the car loosening the nut to let the coolant out when I heard a metallic 'ping' from one of the axel stands. I decided to check it out and it had sheered one of the three lower bolts!
I was lucky, as the jack was also supporting that side of the car, and the stand didnt fail completely, but it could have been pretty bad as I was over that side of the car.
Lesson learnt, don't buy cheap collapsable Chinese axel stands from Screwfit. Going to be calling them up on Monday to express my concern.
