Speedway Motors 91015805 Details

This valve is used with Speedway's aluminum T-bucket radiator (91015600). It threads into a 1/4" NPT hole in the top radiator tank and it limits the pressure in the radiator to 15 psi.

The aluminum T-bucket radiator does not use a conventional "pressure" radiator cap, rather it uses the decorative "T" caps to seal the neck at the top of the radiator.

The arrow on the valve indicates the flow from the radiator if unit has arrow noted on side of fitting.  If no arrow is noted, the radiator side of the fitting or 'inlet'  side can be identified as the end with the allen hex fitting threaded into the end of the unit.  The oposite end or the smooth bore end on the opposite side is the 'outlet' end or the over flow hose side.
