LOOKING FOR BAD HG VIDEO

As title says: Everyone talks about a "tea kettle whistle" when you have bad HGs, but I can't find a video or audio of this. Anyone?

Oh and yes I know about how to properly diagnose HGs, I am just looking for the video of the sound

Type that phrase in the search function

Or check Youtube.

I've looked at both options - no videos of hissing associated with HG failure. Lots of videos on pressure testing the degas tank, no vids showing the actual sound that people describe.

YES! Thank you - you tha man!

I was worried because I noticed a lot of pressure in my cap when I opened it the other day after running the truck for a while. THe fluid came up a little bit, but nothing crazy. No puking, max EOT I see at 65 unloaded is 199-201, ECT usually stays around 190. I did see some white steam/smoke during cold starts only. Truck fires up with a puff of black smoke, then nothing, then some white smoke/steam for 30 seconds to 1 minute depending on how cold it is. Then smoke dissapears and nothing else.

Glad to get the video - because I don't have that tea kettle whistle as shown in the video.

These are pressurized cooling systems.
Even if it's puking, it doesn't mean blown HGs... Could be the the EGR cooler is blown, or the oil cooler is clogged

Agreed - but with a spread of less than 15 I think (hope) that it means it is not blown. I've wanted to delete the egr but it seems like everytime I tear into this engine I **** something up (see thread about stripped FPR housing during blue spring mod).

Yup. Gotta be careful. Ron broke an injector clip on his... That was a biotch
