Oil & Coolant leak
#14
Did y'all order the water pump with the sprocket attached (ACDelco 251-751) or the one without the sprocket (ACDelco 252-821)? I'm fine swapping sprockets and bolts to save $50 if it's a simple swap.

If one is already replacing the water pump, how much extra time is required/added to replace the timing chain and balancer(?)
I don't have a way to remove the engine and I'm working on an uneven (sloped) driveway using wheel chocks...am I nuts for even thinking about it?
If I have to remove the head or block to do the timing I'm 99% sure I'm skipping it and will sell the HHR within a year of replacing the water pump.

Don't need a sprocket. No need to remove engine. Replacing chains makes it easier to do the pump since you don't need the sprocket holder tool, but is a bit more complicated. I would figure 2 more hours more for someone who has never done timing chains.
Just changing the pump you don't open the chain cover, work from the back.

Make sure its not something as simple as the valve cover gasket as well..... Start simple before going head first into a complete chain job or replacing the water pump; I dont think the water pump fails too often and the only time chains fail is improper oil change intervals and failed tensioners. More people have caused issues than solved them by replacing the chain proactively.
