Hi I recently purchased a 2003 sc430 and my mechanic said it needs a replacement cambelt and water pump. it has done 74,000. He is happy to do it as long as I find a tool to loosen the crank shaft bolt. Hence my search for the above. As it is only needed once it seems excesive to pay £70 from the USA. Any helpful suggestions, he has already ruled out not using the right tool. To buy or borrow please
