MGB Water Pump for 5 Bearing 18GB to 18GG Engines. (With Gasket) GWP114.

MGB Water Pump for 5 Bearing 18GB to 18GG engines. GWP114.

To try and de- mystify this a little bit:

The nominal  "height" of this pump, when standing on its Impeller measured to the mounting flange for the Fan-belt pulley is 129mm

Take care, particularly when cars may have had Alternator Changes etc, that your Water Pump may not be the original set up for the car.

 Supplied with a Gasket as pictured

For earlier 18G and 18GA engines, see GWP115

For later 18V engines, see GWP130
