I am trying to replace the front crank seal on my brother's 190D 2.2. It's an '84. One member here said to use an impact wrench which is what I tried. that obviously didn't work. How can I keep the engine from turning over to get a break-over bar on it? Also, should I need a puller to remove the waterpump fan?
Thanks
David
