Cracked water pump
Has anybody tried repairing hairline cracks with heat resistant epoxy/glue? For me it takes around 2 hours to replace these things, so it's worth a try. Also they are mounted directly to the engine which is why I think they crack, I'm going to try adding small rubber bushing on the bolts to see if that helps

I remember hitting a big pot hole and the next day I saw water under the car. I did an oil cooler retrofit a couple months ago on my 07 so I replaced gaskets while I was at it. I decided to not fix it and went to the junkyard and pulled one out for $20, it's been working fine so far

My water pump just went out today, what is everyone using? I'm thinking I'll go with the OEM thermostat and replace the pump with a cheaper aftermarket. Any reason I can't go with aftermarket on either of these? Important parts so I want to make sure I don't get junk.

I don't have an answer....but I'm curious about the metal water pump I've seen. These seem to fail from various cracks in the plastic housings and I'd think the metal housings would rectify that and take a frequent maintenance item off the list for good right?

It's an N55 and I'll be doing the work. I have x-drive, so it's going to be a pain.

So this was a pain. I was going to drop the subframe so I would have more clearance, but the engine support bar I borrowed from a friend did not work. This would have been a lot easier, because the subframe on all wheel drive is so much bigger than rwd. Anyway, I got it knocked out on Saturday, turned into an 8 hour job due to hose clamps positioned poorly so that I could not get a screwdriver or wrench/socket on them easily. I re-oriented the clamps so that next time I can just get a screwdriver on them.
