Well it is my waterpump. Of course I can loosen the crankshaft bolt. The waterpump is so bad I don't dare drive it to a garage to get them to loosen the crankshaft bolt. I've heard that it could cause the belt to break or come off then the valves hit the pistons. I put the car in gear and put the spark plugs back in and the crank just turns. I've heard the screwdriver in the flywheel doesn't work. I've also heard on here that some people put the wheel on the ground and have someone put the brakes on while loosening the bolt, but how would that make any difference?
Anyway, I'm thinking of breaking off the lower timing belt cover to get to the waterpump. Any thoughts on that? All I really need to do is to remove the timing belt covers to gain access to the waterpump for replacement. Of course later, I would go to a garage and have them loosen the crank bolt and replace the lower timing belt cover with a spare I have now.
