Water Leak

[mike505]

2011 Cruze Eco and I just had to add to the overflow. Took almost a half gallon. A little concerning since the car is only 1.5 years old. I looked and could not find any visible leaks but am not able to get the car in the air since we are 500 miles from home. I need to change the oil next week and I'll look under it then. If memory serves the water pump is only covered for the first 36000 miles? Ours has 61000 on it right now. If it's the water pump are there any how to bulletins? I will do it myself before paying a dealer.

Thanks in advance.....

There's "Good News" for you, the water-pump is actually covered under the 100K-mile "Powertrain Warranty" not the 36K-mile "Bumper-to-Bumper" Warranty:

"Powertrain Coverage
In addition to the 3-year/36,000 mile protection, many of your powertrain components are protected even further with coverage extending to 5 years or 100,000 miles, whichever comes first.

Engine
Engine coverage includes all internally lubricated parts, engine oil cooling hoses, and lines. Also included are all actuators and electrical components internal to the engine (e.g., Active Fuel Management valve, lifter and oil manifold) cylinder head, block, timing gears, timing chain, timing cover, oil pump/oil pump housing, OHC carriers, valve covers, oil pan, seals, gaskets, manifolds, flywheel, water pump, harmonic balancer, engine mount, turbocharger, and supercharger. Timing belts are covered until the first scheduled maintenance interval. Exclusions: Excluded from the powertrain coverage are sensors, wiring, connectors, engine radiator, coolant hoses, coolant, and heater core. Coverage on the engine cooling system begins at the inlet to the water pump and ends with the thermostat housing and/or outlet that attaches to the return hose. Also excluded is the starter motor, entire pressurized fuel system (in-tank fuel pump, pressure lines, fuel rail(s), regulator, injectors, and return line), as well as the Engine/ Powertrain Control Module and/or module programming.

- For trucks equipped with a 6.6L Duramax diesel engine, the diesel engine, except those items listed under “What Is Not Covered” later in this section, is covered for 5 years or 100,000 miles, whichever comes first."

I have noticed the same problem with my 2011 LT. I have owned mine since march of this year and have filled the overflow twice. No visible leaks and no coolant smell. Would like to see if anyone else having a similar problem and what the dealers have done to correct if anything.

That is very good to hear. It needs to go in for the last 2 recalls so I'll let them deal with it. Wife can use my Mariner a day or 2.

Djc83 - I will post what the dealership says.

My ECO has florescent dye in my coolant right now. I dropped about an inch in 4,000 miles of driving. Waiting for it to drop enough to be able to hunt down the leak.

This is my wife's commuter. It goes 120 miles a day if she only goes to work and back. Don't want her having troubles and I don't want to have to work on something this new.

GM is aware that Cruzes were shipped with defective water pumps and are working on the problem. I'm in direct contact with two people from GM powertrain regarding this issue and will create a new thread as soon as I get some information.

I noticed mine was getting low when I changed the oil last weekend. I need to get some of the proper coolant to put in there. I better not have to take this thing back to the dealer again.

Its probably the water pump. I just had mine replaced at 22k.
