weird siren sound?
This is my first PSD and was woundering if the loud siren sound that is coming from the engine is normal?
I was pulling a small hill and near the top of the hill the engine started sounding like it was winding up to blow!
This has happend a couple times, and I have only towed about 100 miles and only went up a couple steep hills so far.

They sound like jet engines.
They sound like jet engines. My first answer was Mother-in-law.....usually the whine is constant in a situation like that...

It was hot as hell this weekend and I was going thru some West Va mtns and I heard the noise for the first time as well. Definitely the fan.

Quick question. I was pulling our trailer through the mtns this past weekend, I too heard what I assumed was the fan, based on what I've read on FTE before. But I noticed it seemed to get loader if I pushed the throttle. Is the fan variable with engine RPM? In other words, when there is a need for fan cooling, does the speed of the fan vary with how "hard" the engine is working or is it just a simple on or off?
thanks

the fan speed varies with engine temperature(actually runs with P/s fluid) technical name is hiscotronic. turbo sound will be higher pitched, also changes, only with engine load and speed.
