2-1/16 diameter Wittek hose clamp fits 5/8 hoses.







Original-style "hightower" hose clamp produced by Wittek, the original manufacturer for GM. The clamp is stamped with the correct measurement.

These are GUIDELINES for usage; you should measure the

hoses ON YOUR CAR to determine the actual size needed.

5/8" heater hose -- W34 or WD3_ _ _

3/4" heater hose -- W40 or WD4_ _ _

*typical upper radiator hose -- W66 or WD1_ _ _

*typical lower radiator hose -- W72 or WD2_ _ _

*Due to production variations (larger bottom radiator hose

than top, for example) and variations in the thickness of

some aftermarket or replacement hoses, you may find a clamp

to be listed as too small or too large for the hose that is

currently on your car. MEASURE FIRST!

HOW TO ENTER DATE-CODED HOSE CLAMP PART NUMBERS:

Enter the base clamp number (WD1, WD2, WD3, or WD4)

followed by the quarter and year of the date code desired.

Ex: WD1 clamp dated 4th quarter of 1970 = "WD1470"

Note: Only 1st and 4th quarter dates are available.

So, a part number such as "WD2270" or "WD2370" will

not work!
