blower sound

[RGutierrez]

My first post. Just bought a 2001. 5 2500 6 spd HO. The wife and I were on the road with the cruise set at 83 mph no load. It was about 102 degrees and I thought I could here some low pitch and faint sound of a blower (not turbo) coming on and off every few minutes. Engine temp never moved from 190. Was it my imagination? Didn't hear it on the way home but it was cooler then.

First, welcome to the insane side of CTD ownership, watch out for the "BOMB" disease



It's probably the A/C compressor clutch cycling.

Did you have the heater-a/c controls on?

Maybe the fan?

 

[RGutierrez]

Yes I had the AC blasting. The sound would spool up like a low voltage motor not really a clutch that would engage and it was barely audible. Would the AC clutch engage slowly?

Sounds like it may have been the radiator fan engaging in that case.

A friend just suggested that it might be the lift pump. Does the lift pump cycle? Can you hear yours?

its the mighty roar

of the radiator fan kicking in.



Man that sucker is loud!



its not the lift pump

More than likely the radiator fan. It will do that if the temps are just right.

Thank you all. I love this truck. I also like the TDR and all who support it. Thanks again.
