Hoping first of all you have access to your Genny. Both top and Pulley side covers need to be removed , have the new belt ready- same part number, don't think yours has a belt adjuster. remove the water pump pulley and install new belt,may be tight but should be when re-installing the pulley. Start the Genny with covers off to assure all is ok then button it up your done.
I'm sure others will chime in, this is how we changed my friends last year- took less than an hour. but the Genny had a slide out the front.
