Okay, so about two weeks I swapped my EA82's longblock. It came with a brand new water pump. The first day, I noticed some coolant loss, but it was a combination of bleeding the system, letting coolant pump through every hose, and I didn't fill up the overflow tank. By the second day, she was holding coolant nicely.
About a week later, I notice the temp gauge is reading a bit higher than normal (not overheating though). Up until then, I noticed no coolant loss, and I was checking it every day. However, the radiator went dry and there was no coolant in the overflow tank. I noticed no visible leaks. Filled her up and wanted to double check the coolant to make sure.
Wasn't noticing any problems, until I turned the car off when I got to work today. As always, I look back at my car when I walk away, haha. But this time, I noticed coolant was dripping pretty fast out the bottom of the car. I crawl underneath, and find it's dripping from the oil pan onto the skidplate onto the ground. Pop the hood, and notice no visible leaks. Completely dry of coolant, but yet it's still dripping out onto the ground.
I had to clock on, so I left the car sitting. Nine hours later, I need to get home. First thing I did was adjust the metal pipe that fits in between the driver side radiator hose and the water pump. Adjusted it so it sits better on the water pump. I start adding some coolant, and it starts dripping out the bottom again. Again, no visible leaks.
Luckily, I only live 5 minutes from work, so I was able to drive it home. Got home right as the temp gauge reached its normal readings, so it didn't overheat. Turned the car off, and noticed smoke coming out of the grill. Pop the hood and find coolant sprayed around the water pump. At this point, it is NOT dripping coolant on the ground.
So anyways, anyone have tips? I searched topics on water pumps, but there aren't many threads about it. Best solution I could find is that new water pumps will do this, especially if there's debris in the cooling system, and it'll eventually fix itself. I can do some work in the morning, but should I just run the car a bit more and see if it fixes it? Oh, I forgot to mention that I've noticed no other problems. No overheating, no coolant in the oil, no oil in the coolant, etc. Here is video of it dripping out, and what happened when I got home:
Thanks for any help!
