Reply to "Waterpump plug ?"

The Theory about hot spots and uneven warm up is very interesting.

The way people talk about it, they make it seem like the heads are going to get a hot spot and crack. It sounds like if you run a non-bypass water pump, that only horrific things will happen to the motor.

While the uneven warm up MAY be true, in the real world, there in NO NOTICEABLE warmup or performance difference with running a non-bypass water pump.

I ran one for YEARS without noticing any issue. NONE of the doom and gloom issues happened in my case with a dreaded non-bypass water pump.

However, the Cleveland design works well the way the engineers intended. So there is no reason not to run the Cleveland design. Unless of course, you want to run a non-Cleavland T-Stat or a non-bypass water pump.

My only point is this, a non-bypass water pump works fine. Nothing bad is going to happen if you run one...
