Motorhome overheating

Have a 1994 Georgie Boy Swinger with a 7.4 liter gasoline motor. Where can I get a replacement electric fan as it is only coming on periodically causing motor to overheat

I wonder if the problem is the temperature sending unit on the rad or engine rather than the fan itself?

Sounds like the temp switch is bad or set to low. If the fan comes on it is most likely ok.

While I won't swear to the engine in your model, the Chevy 454 (7.4 L) has a clutch driven fan on the motor and 1 or 2 auxillary electric fans in front of the radiator. The electric fans have a separate temp sending unit in the block, and usually come on in stop-and-go traffic types of situations.

The sending units are available and not too hard to replace, or you can wire the fans to a switch on the dash, and turn them on whenever you feel the need.

Is your motor overheating (what do you mean by that?) at speed, or only in traffic/idling?

You can get complete cooling fan set ups at any auto parts store or speed shop.

If I'm not mistaken, those fans are hooked to the A/C unit. If it is like my 1990 there is a relay just above the fans. I ran override switches for the fans so I can turn them on at anytime. Those fans will not cool the engine they are an aid if your sitting in traffic but on the highway they won't make a difference. Like Senior Chief said there most likely will be a declutching fan on your unit. That declutching fan will move 10 times the air that those electric fans will move. Now that being said it sounds like a radiator rebuild/replace might be in your future. There are a ton of us that are/were in denial about the radiator. IT was the best money I spent a few years ago to get mine recored.
Back to the declutching fan if it is working it will ROAR under the doghouse when it is working.

I've said it before, be sure all sides of the cooling cores ahead of the engine fan are clean on both sides and not blocked with crud. 18 years ago it was clean.

Thanks to everyone for the help! I did not let you all know that our coach is heating up when going through the mountains. We are loaded very heavy and towing our car. We replaced the thermostat and test drove 6% grade to about 5,400 ft. I did hear the "growling" in the dog house at the beginning of the trip but after about 10 miles growling stopped and overheated again. We will try some of your suggestions and if anybody has others we would welcome all. We are grateful for all feedback. If anybody sees our camouflage coach please honk and wave.

Really won't be a growling noise as much as it should sound like the transmission down shifted and the engine is redlining. That's how it normally sounds.
