Sounds like your runnin' the **** outa that truck. Why don't you take it easy for awhile.

What color is your windshield wiper fluid?

 

Windshield washer fluid is blue.

I am going to check the heater hoses tomorrow in the light as its is supposed to warm up to -20 or so.
I have never seen an A/F leak like this in my life. But if all the glycol is being burned up from the exhaust heat maybe it would freeze?
But what are the chances that it would all fall onto the hot pipes and not the ground.
Really, I will go insane if I dwell on this anymore tonight.........
I hate broken vehicles in the dead on winter and driving my FJ40 with a soft top is not very inviting.

 

I think I figured it out.

I went out this morning to drive the kids to school (we live in the country) and no leaks, nothing.
So I get home and crawl under the truck and look under the hood, nothing.
I can still see the stained snow and the stained pipes so I picked up a chunk of snow and placed it on top of the pipe.
It fizzled and hissed and the run off was yellow!
So I tried a few different locations and same thing. The melting snow on the pipes turned yellow.
We have had 2 good blizzards lately and I bet the snow was packed everywhere and melted when I stared up the truck.
Must be some sort of coating on the pipes for it do do this.

 

Snow? What is that?

There's only three seasons in Texas: Summer, Hunting, and Christmas...



saskdiesel,
Sounds like you got some road salt/grime or some such trapped and it started oxidizing, looking like yellow pee....nothing to worry about I'd wager.

 

Man you got yellow snow up there!
keep it, but don't eat it!!!!!!!!
Now go have a cup of joe !

We all can relax now ,thought we were going to have to take a road trip for a repair in western Canada!!!!
You better have lots of firewood !

Mr Big do those buzz tails like the cold weather????

Rich

 

I had to go out and try this again.
This time I packed some snow into the y-pipe shield and started it up.
As the snow melted it looked like my truck was having a ****.
I will keep an I on this but I think this is the cause. Good thing to as I don't feel like pulling the heads off in the winter.

 

Not so's you'd notice...but they won't say.

I have noticed that they when they coil up by my fireplace they yawn alot - sure sign it's apt to get cool.

You don't happen to need a few do you? I could FedX you a couple...

 

That makes sense. The only time I see that color on the pipes is the mornign after I wash the truck. Good work saskdiesel.

 

Snow turns yellow with heat?! WOW!? Wonder what's in your air up there!

Can you put this snow on other heating sources and have it change color?

 

Nope.
It only has yellow run off on the Ford. None of my other vehicles have ever done this.
Weird eh!

 

Weird Stuff!!

 

I just noticed you are from Hawaii.
So I don't know if you have ever seen the different kinds of snow.
The kind of snow that blows into every crevice during a cold (-30 or better) blizzard is very fine and granular, like powder.
After it sets it becomes very hard. You can walk on top of a bank right up to the roof.
I always open the hood of my trucks after a good storm to see if the engine is completely covered or just a bit snowed in.
When is covered you have to remove all the snow in the fan shroud and as much as you can from everywhere else or a lot of ice can form as it melts.
There must be someone from northern ND that can add to this!

 

He just ran away to become a cop! He's not a Hawaiian native

I hate to say it, but I have to - you're not color blind, at all, are you? Even mildly and might not know it?

It's funny what a certain color looks like when you're color blind, even slightly. I can imagine that rust color would look yellow if you can't see red well.

Not a down, just wondering?

--

Also, I wonder if the roads (if any) are salted? Road "salt" isn't necessarily sodium chloride like table salt. It might be potassium chloride, calcium chloride, and others I might not even know about.

That salt, corroding the mild stainless exhaust, just might create a yellow color...

Just a theory... but at this point, anything goes...

 

Nope, not color blind. My job requires that.
I wonder if these pipes are galvanized from the factory and its deteriorating?

 

I don't know, they are supposedly stainless (obviously very mild) but the pipes on my '01 look like they are galvanized. Yet, obviously some type of stainless.
