Radiator Fan in Engine Compartment
Has anyone put a radiator fan (or any fan) in the engine compartment to help move air around the engine?
Our ST350 gets a lot of use rolling in parades at a crawl. This last parade (July 4th), I noticed that it put out a lot of heat. A lot more than normal. Granted, it was a hot day. So, I got to thinking that putting a fan in the compartment to either help pull the hot air out or to pull cooler air in would help it out. Thoughts? |

Re: Radiator Fan in Engine Compartment
For things like parades,you can remove the access cover behind the seat.The problem with fans is getting proper flow,if it pushes the air,it needs a good vent to release it or it will just air-lock and get hotter.Hope this helps.

Re: Radiator Fan in Engine Compartment
There's not much of a access cover behind the seat.
Most of the time, I tip the dump bed back a touch. |

Re: Radiator Fan in Engine Compartment
Hey Tegger!
I was gonna create an individual thread but you asked..... I also had the heat in the compartment issue. I live out here in the Southwest and do a lot of desert and dune riding. A lot of times, the temps are 100+. We all know the greatest enemy to any engine (especially an air-cooled one) is HEAT. I have an EZGO TXT with a big block V-twin. My engine area is pretty full. Also, adding to the heat, are a set of stainless headers. So here's what I did: I measured the space I had available in the front panel and found the largest fans I could. One is a 7 1/2" and the other is a 4 1/2". They are Spal automotive fans made for cooling radiators etc. These fans are puller type. They bring air from outside into the engine area. Now I placed the large one so it mostly blows across the header and other blows across the top of the motor (onto the air cleaner). The air continues out the compartment through the rear. I drilled holes in the front diamond plate to allow air in. I used 2 marine grade switches and wired them with fuses as well. Also to help, I wrapped the header to help keep the heat down and i used a fireproof insulating blanket under the seat to protect it. Now I don't have any temp gauges to verify its effectiveness, but just feeling under the seat I can feel a difference. Gonna have to do some tests maybe with a infrared thermometer with the fans on and then with off. |

Nice setup, LVCJ!!!
From what I can tell, it appears that the engine compartment in the ST350 is a little longer than the TXT, but your post has gotten me thinking though. Thanks! |

Re: Radiator Fan in Engine Compartment
I like the way you did that where did you get the fan and do you have a part #

Re: Radiator Fan in Engine Compartment
These are what we use on our garden pulling tractors. I get mine at Midwest Supercub
High Velocity Cooling Fan . High Velocity Cooling Fan View Full Size SKU: CF $32.23 Quantity Draws just 2.6 amps-145 CFM. Measures 3” around and 5” long. Great for keeping engine cool, just hook it up to a toggle switch, can cool an engine down in just a few minutes. Prevents overheating which can damage your engine. Should be bolted behind the engine or grille; bolting the fan to the engine directly will cause too much vibration. Category:Chassis Parts, Miscellaneous Parts . .

Re: Radiator Fan in Engine Compartment
I think will put one the same size you put in the front on the side so it will blow over the motor and wrap the muffler. I have a 3inch muffin fan that I am going to put in the back behind the carb to pull air in from the back of the cart.
