Looking at the part in Rockauto, says:

"It Is Necessary To Remove The Timing Cover And Exhaust Manifold Assemblies To Replace This Pump. These gaskets will need to be replaced And Are Not Included With This Pump."

This wouldn't be accompanied by an unexplained oil loss, would it?

I just replaced the water pump on an 06 Malibu 2.2 litre. Not sure if it's the same engine. it was a real treat.

It is a Quad 4, GM just changed the displacement slightly & dropped the Quad 4 name. The Ecotech is closely related/Evolution of the Quad 4 but they made the WP easier to change with the use of a special tool.

One word of advice. Pay someone else to do it and make sure they change the thermostat. It has been a long time since I've done one and don't miss it. Exhaust manifold, timing cover, chains need loosing and most importantly the bleed process has to be followed or you will replace the head. Depends on mileage but would not be a bad idea to replace the chain and guides.

Paying someone to do it is likely more than the car is worth.

Uggghhhh. My dad had a quad 4 that needed a water pump. I scrapped the car as I didn't want to do it

How long does the water pump on the Ecotech tend to last ?
Cruze is coming up on 120k - just flushed the cooling system.

But if you buy parts and spend time doing and no problems you will be able to learn a few things. If you have it together and you get a bubble in system on this particular engine head is wiped costing more than it's worth. This is not a DIY job on this vehicle. If a shop screws up they eat it.

When I say Ecotech.....I'm referring to the 2.2L & 2.4L engines with the chain driven WP's. (The LSJ & LNF 2.0L boosted engine as well)

The 1.4T & 1.8L used in the Cruze are Opel engines & share nothing in common with the above engines. The WP on these engine are a weak point but EASY to change!
I'm guessing you had the Timing Belt changed?
