Description
Water pump for the Mazda Sentia and MS-9. GMB GWMZ-53A, made in Japan, one per box.
Sat in a warehouse its whole life. Scuffs and creases all over the cardboard, none of it on the pump.
The label gives the part number and the two model names, W/PUMP MAZ SENTIA MS-9, and nothing else. No engine, no chassis code, no years.
What the catalogues add. GWMZ-53A is sold in the United States as GMB 145-2125 and listed against the Mazda 929 from 1992 to 1995. The Mazda numbers are 8AH7-15-010 and JE48-15-010E, along with their A, B and C suffixes. JE is Mazda's 3.0 litre V6.
Which V6 is yours? The Sentia and MS-9 were sold with two different V6s, the 2.5 and the 3.0. Everything traceable about this number points at the 3.0. If yours is the 2.5, send us the number off your old pump before you buy.
It is an alloy housing with a metal impeller and no pulley attached. Weight is about 1.5kg.
Fitment
Mazda Sentia and MS-9 as printed, and the 929 HD by cross reference. Give us your chassis code or your rego and we will pin the engine down.
Fitting
- Drop the coolant and keep it off the driveway. It is toxic to pets.
- Scrape the old gasket away without gouging the alloy, then check the face is true.
- Nip each bolt in turn rather than pulling one up tight on its own.
- Refill, run it with the cap off until the thermostat opens, then cap it and recheck cold.
- Best fitted by a qualified mechanic.
