I started noticing leaks under my car when I started it. They began small with a redish color to it. I just had my transmission fluid replaced at 63k (about 2 weeks prior to the leak starting) so I thought it was transmission fluid, maybe a bad plug screwed in wrong.

After the car warms up and driven, the leak would stop. Rinse and repeat for about another 2 weeks before I was able to get it back into where it was maintenanced. Turns out it wasn't transmission fluid at all, but a coolant leak. Apparently my water pump had failed along with a piece of the plumbing. It was covered and they replaced the water pump & piping and all is well. Car runs great, but I can't help but feel the possibility of damage done internally for driving it a few weeks with a dead/failing pump. No CEL's ever went off, temp guages were all at normal operating temps every drive and everything seems just fine... I never hammered it while the leak was there for obvious reasons.

My question is, is it possible losing that much coolant over the course of 2 weeks every startup do any longterm damage? Is there anything you recommend I should check?

If the car did not overheat you have nothing to worry about. Even if it does overheat the car has some fail-safe programming built in to shut off cylinders and lastly shut the engine off when overheated (Although I would not fully trust it, if it overheats shut it down). Only concern would be debri in the system so I would just keep an eye out maybe flush the system to be sure.

Mine started leaking last week, and left a 6 foot by roughly 4 inch wide puddle on my garage floor. The coolant reservoir was only about an eighth inch below the minimum line when I noticed that. No harm done. I think you're safe.

Do you plan on replacing the pump yourself? If so, get a shorter M6 bolt for the steel crossover tube that bolts to the pump. Some replacement pumps aren't tapped as deeply as the stock pump, and the bolt bottoms out. I had to use a M6x1.0 25mm bolt in place of the stock bolt on the Duralast pump I put in my car.

Your good. I drove my truck two gallons low to the mechanic because I didn't have time to mess with it. Got a little warm on the highway, but even then, not a big deal.

By how much was it too shallow? Enough to notice during assembly?

Shallow enough that with the bolt tight, there was still a good 1/8th inch of movement. You could probably even go down to a 20mm long bolt. That's still plenty of thread engagement for that kind of bracket.
