Probably a shot in the dark, but does anyone know how hot the engine bay gets - say at the upper part of the firewall to 6 inches below that, in the summer at 100 degrees outside sitting in bumper to bumper traffic for an hour?

Does this qualify to be added to the CK5 Trivial Pursuit game? :doah::rolleyes:
 
I'm gonna guess somewhere north of 240 degrees, if you have the a/c on. :yikes: I can't touch ANYTHING under the hood of the Suburban if the a/c has been on for very long. It drastically raises the underhood temps to have the extra heat from the condensor.
 
No idea. Probably not as hot as I might guess, so I'd probably have to stick a thermocouple under there to measure it someday. My cooling system runs at about 200, my oil runs at about 200, and the trans fluid runs at about 155 (those temps are all from gauges).
 
I would say it varies the entire time due to how much heat is being disapated , or not .

For example a BBC equip'd Suburban fully loaded pulling max weight for long periods will have severe temp spikes if shut off imediately with no air flow to cool things off .
Underhood temps can be outrageous but constanly varying.
A over worked engine can have a manifold temp spike close to a 1,000* but that is localized heat and what the ambiant temp is a guess.

True, and the only way to really tell what it is at any given time is probably to stick a sensor there, hook it to a dash gauge, and monitor it.

:haha: :haha:

I used a Toyota 22RE to heat up a can of soup durring one of our hurricain induced power outages . BTW - note to self , remember to vent the can for heat expansion.....:D

Damn, and I thought brake fluid smelled bad when it burns on the manifolds (well, it does), but the thought of like clam chowder :haha:

Campbells chicken noodle Select - smelled a whole lot better in a bowl than it did on the manifold.....:haha:

:haha: Maybe not burrito. Maybe a cake-making capable oven :haha:

I've cooked soup on my 22RE in the Toy many times. Partially got the K5 cuz I was tired of being stuck places that then required me to heat food on the engine. Of course, with as often as I get stuck with th K5 I guess not much has changed. :haha::haha::haha:

Seriously, I wanted to see if it was possible to mount an automatic thermal activating head firebottle in the engine bay, instead of having a manual one mounted in there. I was going to call their tech support to see if they could customise the activating head for our engine bay temps.

Thanks for the responses guys.
 
Without knowing the exact heat range, I don't think they will. Just like a regular sprinkler or fire damper, the heat range is whatever the fuse is set to melt at.
 
I live in Los Angeles. We need to anticipate everything.

Haven't had a fire in the truck, but I thought I might as well be prepared, as long as I was prepared for every other probable manmade or natural disaster (we tend to have them here).

I'd like to have something set up that's better than blasting ABC powder in the bay after I manage to get the hood up (no easy task sometimes). And just in case there's a fire starting in the bay doing damage before I noticed (being as easily distracted as I am) it'd be kinda cool to have something that would just go off by itself. Not very realistic I suppose.

Guess I'll just go with the manual system. Now the question becomes, do I mount the firebottle in the cab and run tubing into the bay with a nozzle into the cab too? Or run 2 firebottles - one for cab and one for the engine bay? Cleaner with 2, but then there's 2 handles, ensuring an available mounting surface in the bay that doesn't get too hot and positions the firebottle correctly (it needs to stand up or lay on its side crosswise to the front), etc.

With one firebottle, I'd mount it behind the driver's seat, then run tube down thru an already unused seat bracket hole in the floor. But then I have to use several connectors, run tubing under the floor into the bay, etc. Looks a little sloppy to me.

*sigh*
 
There's being prepared, and there's jinxing it...

Methinks maybe use a shop between Barstow and Las Vegas for this project - sorta as preemptive strike...??

:haha::haha::haha: So I guess you know that I've been to most shops between here and Vegas. Also used shops IN Barstow and in Vegas. And in St. George and Cedar City and SLC and Buttwipe and most other towns within 3 days driving from L.A. :haha::haha::haha:

kick ass i am wheeling with skigirl. She makes wheeling cake:D
