When I pulled the water pump cover off to replace it with a black one I found built up rust on the front two bolts and rust on the outer gasket. I was surprised to see a ton of caked on dried coolant in the pump assembly. I had to vacuum it out. I just wanted to check and see if this is normal. I ordered chrome screws, a new inner and outer gasket as well as the two little orings to replace them. I also plan on using gasket sealer on all mating surfaces too. Anyone else have this problem or suggestions on how to better seal those areas? I have not experienced any overheating or such. My next check is the bolt under the alternator cover like others have had problems with. Thanks for any advice on this.
