• This kit fits all 5/8" and 3/4" heater hose systems which is just about 99% of all vehicles out there.
• This kit DOES fit 5/8" hoses contrary to several reviewers. It does take a little M. A. N. to get a 5/8" hose on the nipple but it can be done. If needed you can use a little soapy water to get the hose to slide over the barbs on the valve.
