Once you read down to the end of the first "read this" I posted, you'll find a link to click to go to page 2, "radiator caps". Direct link is here. At the end of that page is a link to page 3, radiators…which links to page 4, coolant (read the coolant page before deciding on a radiator cap), which links to page 5, fans.
