They really need to be designed with a cooling system with a radiator and fan for the way we use them.

Best reply i have ever read., thanks

I agree that the carts weren't designed for how we use them. But air cooled VW Bugs did fine. I will definitely be making some changes to vent the engine bay a bit better. But that is more for my comfort than the engine. I can put the shroud back in the cold weather to heat the cabin.

While I agree golf carts were not designed for use as personal transportation vehicles, they work just fine for that use without a cooling system. Yamaha made a great change by adding independent rear suspension, but needs to change the negative camber in the front end alignment and rewire the voltage regulator setup as those are both designed for slower speed stop and go driving on turf.

Air cooled engines do just fine in the heat, especially when they are not running when the vehicle is stopped (not getting air circulation). Look no further than all the air cooled zero turn lawn mowers that are working very hard for several hours daily during the summer heat.

My electric Yamaha doesn't have a cooling system and it stays cool as a cucumber. No heat what so ever comes up from the seat. And it is quieter than those Quietech gas carts. Having said that, I don't drive our electric Yamaha far enough to have to worry about range. I understand the need for gas carts for those who travel long distances without the opportunity to recharge an electric cart.

And they sound like lawn mowers, especially when in the tunnels. YIKES!

But.......aren't the air cooled engines OK for the engines but make life uncomfortable for the occupant of the cart? Why add heat to the passenger compartment in the heat of the summer, especially where a person sits?

The heat underneath the seat is unnoticeable unless you lift the seat. Having a dark colored seat, absorbing sunlight, would make a much bigger difference on the people sitting on the seat in any type of cart. Seat color and seat heat really make a difference if you park in the sun or constantly get in and out of the cart (golfing).

Mine is very quiet. Not as quiet as an electric, but I only filled the tank in six months.

I also have no fears of range reduction when adding more electrical components to my golf car.

Electric is nice, but the gas ones are very quiet these days.

That is true, though some manufacturers are recognizing the transportation side of the market such as Star EV, GEM, Crown and others, which are all electric, and therefore have no need for engine cooling system. They are designed more as LSV’s with transportation as the main function.

As far as Gas Golf Carts, you are basically sitting on top of a 13.5 HP lawn mower engine (the newer QT’s are even less HP) that’’s put into a hulking fiberglass body with fancy seats, and a sheeve belt drive. If you drove your John Deere or Cub Cadet mower like you do your Yamaha QT, they’d overheat, too. They are basically the same as the little Go-Carts we built and raced in the 60’s.

Yours is quiet because they seal off the engine area so you don’t hear the engine noise. The problem with that is that an Air Cooled Engine needs Air in order to Cool. Probably fine if you are just playing a close by 9 hole Executive course, but not good if you are running from say Spanish Springs to Southern Star for a tee time. Doing that, the engine will run Hot - too Hot - but of course they weren’t designed for that anyway.

I had heat coming up between the el tigre bucket seats in our new Yamaha. I took it back to the Villages golf car store at Everglades and they installed additional foam insulation where the seats meet the engine compartment. This solved the heat radiating issue.

I still had concerns about the heat in the engine compartment. The golf car store told me some people removed the skid plate under the engine compartment for heat dissipation and it works well. It is not as quiet but doesn't get as hot. I have not tried this yet but probably will when I get back down to the Villages.

All this talk about Yamaha Quiet Carts running too hot. I really don't understand all the hoopla. Our 2017 is on its 7th year of running now and we run all over TV in it and never see this issue. Are there just some model years that have this issue? I think for the past 7 years they are built all the same but maybe I am wrong. ??

Engine heat from my 2023 quiet tech does indeed come up between the cushions. It may depend on seat type. I have the nice bucket seats.

No they don’t. GCs have quieter muffler that about as big as the engine. GCs engines are governed lower RPM.

I bet That sound don’t bother you when mowing your yard??

I got a sheet of foam insulation from lowes and cut it into a couple strips that I slide between the bucket seats. Works for me.
