Re: Exhaust Manifold Flooding with Cooling Water
Rusty, the pro and con of electric-vs-mechanical pumps is an old story. Fuel pumps, oiul pumps, water pumps, air pumps, power steering mechanisms...
If you lose electricity for any reason, you lose the pump. So a direct mechanical pump is usually considered more reliable and cheaper. If you've got faith in your electricity, by all means, you can go electric. Just remember that if you lose electricity for any reason, you'll also have to shut down the engine or burn it out. And if the electric pump has a loose wire or blows a fuse...you have no warning and again, the engine is in danger.
