Listeroid Engines / Re: Hot Water Circulator Max Temp Rating.

Thank you all for the great advice. You have generously given me ideas to implement on my generator. Mounting the radiator horizontally sounds amazing. I can picture the air just pouring through the fins.

Bronco to answer your two questions

""What is the temperature coming out of the bottom of the radiator? Did you put your pump on the inlet or outlet of the engine?""

I dont remember the temperature exactly but I think it was in the high 100s. And the pump is on the inlet side of the engine (the lower one).

Ajaffa the radiator is mounted vertically like a car radiator but I will look into mounting it horizontally. Also, I do not have a bypass for the electric water circulating pump. I should put one in right away. Or, If I ventilate the radiator adequately should I just remove the pump and convert the system to a non-pressurized? Maybe just use the thermosyphon setup?

This is all awesome info to ponder.

Okay, well I am finally getting around to working on cooling my listeroid 10/1. I have installed a small radiator, a household fan for the radiator and a hot water heater circulating pump. I filled the radiator with a 50/50 solution of antifreeze and water.
My operating temperature on the engine block next to where antifreeze leaves the generator is 220-degrees farenheit after about 20 - miinutes of operation.

Is there anything else that I might want to try in order to bring the temp down some?

The circulating pump has 3 - speeds. I have it on the lowest speed in order to keep from adding too much pressure to the cooling system.

The fan is not pushing too much air through the radiator. The simplist test that I could do is install a more powerful fan.

The radiator is probably something that you would see in a small 4-cylinder car.

Thanks for the help..

I am looking at some Grundfos hot water circulator pumps for the radiator on my Listeroid 10/1. The one that I am looking at is rated max temp of 150-degrees farenheit. Is that high enough to handle the ranges on my generator?

The India "manuals" are very generic, same one issued for a 6/1 or 25/2. Theyoffer little information of value, some of it flat wrong.. Also there are variants of engines called 10/1 with various RPMs and bore sizes.I might have a manual here somewhere. What is it you need to know? I might be able to help

I have been researching radiators and have decided to go with a small one off of a 4 - cylinder car out of the junk yard, add a 120-v household box fan to it and also add a 120-v grundfos circulating pump to it as well. Just wondering whether or not this should be sufficient for keeping the 10/1 1,000RPM nice and cool. I am not thrilled about using 120-v for the fan or the circulating pump but that would be easier than adding a belt and pulley or an alternator.

Thanks for the input. Hope youre having a great day.

Where can I find a manual for a Listeroid 10/1?

We've been using those relatively inexpensive "Grundfos" style hot water circulating pumps with good results. They run on 120v, take very little power and seem to be utterly reliable.

The Grundfos brand is prob top notch and will cost about $130 if you look carefully. The clones are about half that. I don't know how well the clones hold up.

Hello cujet,

If I use a circulating pump does the system need to be under pressure?

Can't wait to delve in. My damaged one is a nice sized one and I had it set up for Thermosiphon (I believe).

Nice.....  I will start researching this.

Thanks for the good info. I will look those up.

Listeroid Engines / How To Choose A Radiator
« on: August 16, 2023, 12:22:59 PM »


The radiator on my 10-HP / 1-Cylinder Lister Clone has 1 - substantial leak at the fitting where the freon exits the radiator. I showed it to my friend who is an old school plumber and very good at soldering and he is recommending that I just try to find another radiator at the junk yard. Is there a certain type and size radiator that I should be looking for?

Thank you for the advice.

LOL   :)
Putting the generator inside the attached garage was probably not the best choice. One day I hope to run the generator on some sort of biofuel that smells good. I work at restaurants so I may be able to get their fried chicken oil. Yum Yum.

Hey Bob,

Thanks for the great advice and the word of caution.

I think the electric fan plus a thermostat to cut the antifreeze  flow off until warm would be the simplest route for me to take. Do you think that it would be ok to put the fan on the radiator where it will pull air from the generator through the radiator to the outside or should I pull the air from the outside through the radiator towards the generator? I would prefer to pull the air from the generator to the outside in order to help get rid of the fumes in my garage which is attached to my house.

Thanks again....

Greetings Fellow Lister Enthusiasts,

Would someone please advise me as to whether or not I should install a radiator coolant pump or fan on my Listeroid 10/1? The dimensions of the radiator are 21" x 41". It is installed above the generator. The temperature of the fluid exit port is about 240 - degrees F and the temperature of the fluid entrance port is about 215 - degrees F.

Thanks for the great help.

Sounds like you have good draft.

We also have a port outside the generator shed where we can screw in the stock "pepper pot" muffler;  I used that initially so I could see the exhaust.  It's a good idea for us to confirm our rich on full load situation with the pepper pot in place just to see.  Thanks for thinking of that Gary.

Our leach field "earth muffler"  is a 24" wide, 3.5 foot deep ditch 20 foot long filled with 3" rock (1 foot of dirt on top of some aluminum flashing).  A section of about 6 feet of 2" ID pipe with holes cut on the sides and downward feeds the leech field.  A section of 4" plastic perforated drain pipe leads out of the last 6 feet and up to a vent cap above ground.  I'd be surprised if this was overly restricting the exhaust.

I will add that I've seen some videos of  masonry mufflers (buried large expansion chamber), that they work very well and would also solve the soot on the solar panel problem.  They just won't clean up the exhaust smell as well as the leach field method.  I didn't invent it, I just appropriated it.  The leach field is the ultimate but takes some digging.

Great video. That leach field muffler system is quite nice.
I like the chimney on the roof of your generator building. Does that capture all of the (secondary) gases coming out of the side of your engine or do you pipe the gases out separately?

Thank you for sharing that.
