Had to replace the crankshaft pulley bolt on my ibiza 6L 1,4 BBY, the one my car came with (from factory) is a 19 mm 12 point with a flat head but the one dealer gave me is 21 mm 12 point with a hollow head?
Looking at the repair manual they do mention two different crankshaft pulley bolts with different torque requirements, flat head 90 nm + 90 degrees vs hollow head 150 nm + 180 degree. What's strange is that the manual does state that the same version of crankshaft pulley bolt that the car came with should be used, so why did the dealer give me the new bolt?
Can I use new bolt without issues or do I play safe and get the original flat head bolt? 150 nm is quite a lot of torque and I don't want to strip something.
