Under hood pad to quiet engine

[TDHoffman]

I was wondering if anyone else with an 05 SD has a noise reduction padding on the underside of their hood. I recently bought my truck and it seems like the engine is noisier than some other diesels. I had an 04 6.0 SD in my shop today and it was much quieter than mine so I popped the hood and it had padding under the hood. Is mine just missing or did they not install it in 05?

Ford stopped installing the hood pad/insulation sometime in late '04.

do you think I could put one on my truck or would it cause excessive heat buildup?

You could add one, the only difference you would gain is noise reduction. As far as hotter temps, here is a write up on before and after insulation. There was on average a 30* drop in temp after I removed the insulation.

05+ lost the hood insulation as well as the cord for the block heaters. only trucks specially ordered or delivered to really cold climates had the cords installed. all ford 6.0 trusk do have block heaters though

Go to Walmart get a gallon of the Supertech 2 Cycle Oil. Next time you fill up put 1 oz for every gallon she takes. It will quiet down.

I purchased mine. I enjoy that it holds the heat in after I trun off the engine and the reduction of engine sound in the cab. There is no excessive heat build up because it does not limit air flow.
