Great product

Used this cap to replace, my old one because I wasn't sure of the pressure rating of my old one. Nice leak free fit, easier to keep clean than my old aluminum one. This and overflow/ catch can solved my over heating problem. Never over 180 degrees even in stop and go traffic on 90+ days

Not a good part

The cap looks cheap and does not fit the walker radiator very well. I had to force it into the neck and then had to use lots of pressure to get it to turn and seal. Used a Stant cap and it fit and turned easily.
