Re: Exhaust Manifold Flooding with Cooling Water
How long it takes to fill, depends on the installation. The water pump capacity, the hose lengths, the muffler volume...too much stuff.
Bottom line is that if your engine doesn't fire up right away, you want to shut down the raw water intake and then scurry back and open it again immediately after starting.
There are probably no drains on your muffler, etc. so if you want to drain things, you'll have to take off a hose.
Why is it done this way? Because its cheap.
