Default Re: Flathead heater continued

When I first bought my car, the heater was just one of the things that didn't work. The car has sat for well over 10 years. When I decided to rebuild the engine I de-rusted many of the parts to include the water pumps. The reason the heater didn't work, was a clogged pipe, on the water pump.

You can see the pipe was completely clogged even after soaking it for 24 hours in rust remover.

Two person job, one to pull the lower hose and one to put their thumb over the pipe, or not, if the pipe is completely rusted shut, like mine was.

Obviously I bought new water pumps, for the engine rebuild.
