I am new to the Dodge Ram. I have a 01 Ram 4x4 318 Quad Auto 41K miles. About every 8 to 10 seconds, I hear a noise in the engine area that sounds like a relief valve or something. The sound is very noticeable. Any Ideas?

 

Turn off your defroster and AC. See if the noise goes away.
Sounds like an AC compressor short-cycling to me, maybe....

 

damn. Beat me to it.

Could be that the Ram was just chewing up the last bit of silverado it had in it's mouth too.

 

Ooohh, never thought of that. I hope it doesn't get sick!

 

The 99 I just purchased was doing the same. One large can of coolant added to the AC system solved the problem. Hopefully this will help.

Both the AC and the Defrost is off.
