Thread: Water piping questions

Are both water pipes that go behind the block necessary?
I Was thinking about cutting the smaller one off And relocation the temp sensors to the thermostat hosting. I don't have heater in my car so I don't Need half of the lines back there.

My concern about eliminating that smaller pipe is that I don't want the engine to not get water in certain parts. If it all goes to the same place them I'm only going to keep the main one.

I particularly Hate these pipes because the two times I've broken something in my engine is been because of them leaking.

Thanks man, that's weird though the water from that pipe goes against the current back into the thermostat housing?

The smaller pipes sends coolant to the head and the other to the block. The other 2 stems off to the heater core. You need to leave them all
