We said goodbye to cracked clutch fans and cruddy radiators. This job is really simple if you have basic mechanical skills and tools. Heating the drain plugs will be the most difficult task, and if you don't feel comfortable with doing that or replacing the water pump, you might want to have a professional technician complete the job. We spent two days on the installation, but if you work straight through, it shouldn't take longer than four or five hours. We did ours in mid winter and the garage wasn't heated, so we took frequent breaks to let our hands thaw out.
