Opel Vauxhall Ascona Kadett Astra Cavalier Water Pump - GMB GWO-10A

Description

Water pump for the 8 valve GM Family II engine. GMB part number GWO-10A.

Never fitted. The box has aged in storage. The pump is new.

The box lists the Ascona, Kadett, Astra, Belmont, Carlton and Cavalier from 1987. It covers the 1600 N and SH engines, the 1800 SE and NV, and the 2000 E, NE and SHE. GM numbers on the box are 1334008 and 90220568.

Catalogues take it further. The same pump is listed for the Opel Vectra A, Calibra 2.0, Omega A and Frontera 2.0. The Daewoo Espero is on the list too.

One thing to watch.

The 16 valve versions of these engines take a different pump. Check the number on your old one against the two above, or send us your rego.

Fitting

  • On this engine the pump sits in an eccentric housing and sets the timing belt tension. A new belt goes on at the same time.
  • Clean the housing bore before the new pump goes in. A pump seized in its bore is corrosion, not bad luck.
  • Drain and flush the cooling system first.
  • Refill with the right coolant and bleed the air out.
  • Best fitted by a qualified mechanic.
