Generator cooling tower tank?

Just a length of pipe isn't going to radiate much heat out...

Yes, and Yes. In fact, easier and cheaper than a relief valve.

Not easily. Why reinvent the wheel? Go to a junkyard and get a good small radiator with an electric fan attached, and note what car it came out of. And get a generic radiator overflow bottle.

A regular radiator will run in thermosiphon mode also, but it works better if there is a water pump in the cooling system. That's why the user them on cars, you can't get enough cooling from thermosiphon alone with a high-horsepower engine unless you use Big coolant lines

I agree with the other poster of why the tank?

Get a radiator and mount it above the engine if you want to go with a thermo siphon system.

Personally I'd look into a condenser. That's what they use on these type engines in the oil field. It's basically just a radiator with the bottom directly connected to the top of the tank (in other words there's not bottom tank on the radiator but rather the tank on the engine is the bottom and the cores connect directly into the tank). There is a top tank and a small fan run by belt from the engine itself.

The way the condenser works is that as the water evaporates from the engine heat it rises up into the condenser which cools back into water which then falls back into the tank. Real simple system with built in thermostat (the boiling point of the water).

For an aluminium filler neck you could try a shop that sells parts for motor racing. In the UK at least these are readily available so you can weld up your own aluminium tanks/rads etc.

So the red tank on the top of the engine is just a cooling tank? That boils and bubbles when you run it?

A thermo siphon system works fine but:

-You need to have fairly large and unobstructed piping.

-The system is self starting if the inlet to the engine is much lower than the outlet. Any hot water needs to rise to one specific port.

-Why not use a big truck radiator? It should be mounted vertically so that you complete the syphon effect.

-The radiator (or larger tank) needs to be on the same level as your engine.

-D> I have put together a diesel generator set, can be seen at:

I would mount the radiator at 45 degrees from vertical and above your engine. my reasons are that flow occurs because the hot water going to the top of the radiator is somewhat lighter than the cooler water going from the bottom of the radiator to the lowest part of the engine water jacket. So the hot water rises. The longer the pipes to the radiator the greater the difference ( but somewhat offset by greater frictional losses ).

At 45 degrees so the air that is heated rises through the radiator without needing a fan.

For noise reasons or ?

If you are planning on using this genset for emergency power you may want to consider using a water pump and a radiator / fan setup from a car or a truck. This way it could help keep the house/shop warm instead of just wasting the heat outside
