WOW! CTD Exhaust can scorch grass!

Idle for a quarter hour, why?

Automatic shutdown should be mandatory on all vehicles just not commerical delivery trucks.

You guys are too much....
You would ridicule someone for using too much TP after dropping a duece if given the chance.

Ron, thanks for the heads up.
Sidecar, not everyone is a farmer and thinks of things like that. Besides OP said he was parked on short grass. Would seem relatively harmless.

Confirm they do get HOT. When we'd manually regen trucks on the ice, even at 30 below zero, they'd melt a rather large area under them. Had one truck tires froze in place after the regen!

I know a guy who returned his new Tahoe because it would not stay running for more than 30 minutes while parked. The guy's dog almost died while the owner was touring a museum that was not dog friendly and the car shut itself off. He was told that GM would not allow that setting to be changed unless the owner was an emergency responder. I guess that if you want to travel with animals and leave the vehicle for any reason on a hot day you have to do it in a motorhome. That is good for the environment!

Hardly a reason to blame GM... Doesn't sound like a responsible pet owner - find out beforehand if pets are allowed. There's always kennels, doggy day care, walkers, or leaving the dog at home?

As I recall there were some issues with Fords starting grass fires when regen first came out and they changed the programming not to allow regen unless the truck moving. This was probably just from exhaust heat. I guess that this is one argument for a lift kit, as if trucks aren't already high enough.

I have heard tales of emegency vehicles that are left idling a lot having expensive repairs due to regen being inhibited. This re-enforces my belief that regen was not related to his problem unless it was already started when he parked.

As for idling a long time, I don't make a practice out of doing that but I did notice that nobody seemed to care if he had a reason for doing so and there are some. One good one that comes to mind is keeping the air on for a dog that is not allowed to leave the truck for some reason.

This brings up an interesting thought with me.

I will never park by one of those rattling trucks in the Wally World parking lot again. :S

Thanks for the tip that has been around since the catalytic converter came out 42 years ago!

Think if you bother to read your owners manual (most people don't), it will caution you about parking on grass or near potentially flammable shrubs. Any catalytic regenerated exhaust is hot as well as the SCR unit under the truck. In regen, exhaust temps can exceed 1000 degrees.

Fire insurance paid up?

Thanks for the condescending, self-serving, and rude comment, and yes, I read the manual; it warns against parking in TALL grass, which can be set on fire. This was a short cut lawn. Point is, the radiant heat off these exhausts is very great.

Apologies all round guys if I wasted somebody's time. Thought
somebody might be interested.

This is a rough crowd sometimes, don't get your feelings hurt. It's just another day on the internet.

I'm sure many remember as well, when ford came out w/ either 6.4 or early versions of the 6.7 PSD, someone placed a painted barstool few feet from end of tailpipe and when the re-gen cycle happened, the paint got blistered off the stool. Then everyone chimed in saying, "Don't park your Saturn next to a Ford cuz it will melt the plastic panels off the car".

No problem.:) Glad you read it. Most people don't. Wasn't being rude, just factual. Have a good day and water the lawn. Wet grass won't burn as quick.

No worries! Watered every day via automatic sprinklers! Never any chance of fire, just over-heated the grass and killed it in that small spot.

Folks; just to clarify here; we're talking grass a little taller than a putting green. No chance of a forest fire, thought we have plenty of those in So Cal!

I've noticed the exhaust system on my truck gets super hot during regens too and radiates a ton of heat. I have no doubt that the radiating heat could kill off grass.

just about every harvest season someone burns up a truck by the engine heat setting a field of stubble on fire
