    63745 is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from Great part I needed a radiator hose filler for my rebuilt 1986 Toyota MR-2. The factory part was made of plastic and falling apart. $86.00 last cost. This part has been discontinued for years and no replacement part available. I found this part at Jeg's and it worked great. Made out of aluminum and fit inline perfectly, should last a lifetime for a fraction of the price. Thanks Moroso and Jeg's.

    what cap does this take? I bought a standard size cap (87 mustang) and it doesn't seal, it fills my overflow bottle to the point it overflows and doesn't build any pressure??

    This uses a Moroso 63320 cap.
