Now people are saying their engine is running perfectly cool, but they are going to remove their water pump housing anyway because of this thread. Am I missing something? Is there really that much of a sheep mentality going on here?





I removed my housing because it was easy to pull and look at, no coolant, motor not hooked up and running but dyno time.

And yes I thought it was a cat housing, which everyone sells.

Now for the question if the housing has a small opening,

IT DOES, will it cause a cooling problem, seems to have for one. Not sure for anyone else

The narrow passage is only the feed ( back to the block ) lower passage on the passage side. All other passage look fine and closely match a factory housing.
