Review on Airtex AW4124 Engine Water Pump by John Martin

Revainrating 3 out of 5

Design changes can be a cause for concern.

recently their design has changed. Now they use a metal impeller instead of white plastic. While this may seem like a good thing, consider that a metal impeller is much more likely to cause cavitation than plastic. The specified Jaguar OAT coolant does not contain the anti-cavitation additives required for this type of impeller. Most likely there will be no problems, but who knows. This device is made in China. :-( They used to be made in Canada. They only came with a paper gasket, while the AC Delco unit comes with a stronger gasket and rubber O-ring.

Pros
  • spare parts
Cons
  • there are nuances
