Rust on frame - too much?

OP,

Your truck looks bad. I hope mine never looks that way.

A point of clarification. Toyota offers vehicle service agreements (VSA) which is not a warranty in the traditional sense. TFS does this to avoid the legal requirements of being classified as an insurance company. But more importantly RUST and corrosion damage is specifically excluded from the agreements.

 

How hot water has to be to not freeze by the time hits frame at -14F (-25C for Canadians)?
Also my water (well) is PH 6.5 should I premix that with something?

 

Toyota frames = shit

Toyota ABS = shit

People who stand up for inferior products due to ignorance = shit

 

Whatever comes out of your hot water tank.
Hose it long enough to warm up the frame.
Air has very poor conductivity, so it will stay warm for a while.
I don't know anything about PH.

 

x2, you need to wait til it's close to freezing or above or if you have a garage to store the truck in that will not get below freezing. Spraying hot water on a steel frame won't warm the frame unless you continuously spray the frame for hours on end.

 

Water is highly conductive, air is not. Hot water will warm the frame up VERY quickly, and it will remain warm for a while.

 

If you were in MA... then I understand the issue....however you as an owner should take care of your truck. MA is a highly salted environment... I know because I lived there.....but I took care of my rig. I only have surface rust. Yours is starting to flake it looks.

Wash your vehicle weekly....rinse it daily in those environments. For now you need to go to town with a wire brush and some POR 15 or alternative rust preventative paint. You could have prevented this damage AGES ago my friend.

 

Steel is highly conductive which means it heats up quickly and cools quickly which means it will not stay warm long enough for the water to drop off if it's well below freezing. That being said, water freezing on the frame isn't a huge deal as long as it's not excessive build up or near something that shouldn't be encased in ice plus the first time you drive the salt will melt the ice away anyways...

Again, better off waiting for a warm day.

 

Pugga: yes, steel is highly conductive, but that doesn't matter unless there is something else that is also highly conductive in contact with it to exchange heat with. Water is highly conductive, so hot water will heat it up fast and easily. Air is highly NON-conductive, which is why the steel will retain the heat for a far far far longer time than it takes to warm it up with water.

Just so there is no miscommunication, I'm not saying that it will sit there hot for 5 hours after you hose it off. But it certainly will long enough that the majority of the water will drip off of it. You won't be blasting an ice sheat at the frame.

In the winter, I, in fact, do hose off my frame with hot water in the extreme cold. It works great. The only reason to wait until it warms up is if YOU don't like the cold.

 

All you people saying spray it off in the winter must have never been in a northern climate. This is not an option where I live.
I do get mine undercoated every year. Seems to be working pretty good so far.

 

I only spray the undercarriage when it's above zero ( 32 for the Yanks )

 

No, I wait for a fluke warm day or do it in a heated garage (my parents have one, obviously not an option for everyone).

If it's a hard winter and never warms up, I never hose it off. I haven't undercoated mine yet (2007) and it's got some rust but it's not terrible. This is the year I think I finally need to start addressing it.

 

One thing I can add to this; the colder it is, the slower rust will form. Each 10 degrees warmer (C/K scale) represents about a doubling of the rate of chemical reactions, like oxidation.

 

Sounds like a better reason to wait til it warms up to hose the frame to me...

 

Sure its option. I lived near where the open lived(s). ...... just do it indoors that way it doesn't freeze. I have surface ruse but nothing near the ops. Had I not taken care of it...I might be in the same situation

 

That shock looks like it hasn't moved in years.

 

Did you ever try that ?
Even water at 120F (what comes from the water heater), by the time travels through hose, then through air at -14F by the time hits frame will be at probably right above freezing point. It will never dry before freezing. So on the end Truck will look like this

I mention PH because only water from city is guaranteed to have PH at or slightly above 7.

 

Seems that you posted your picture data inline, rather than a link to the file.
Read last line of my last response. Yes, it comes out hot. Very hot. Quit trying to argue, you're not saving face. I assure you that it can be very cold out and you can shoot out hot water through a garden hose and it will raise the temperature of your frame enough that it will feel hot if you stick your hand against it.

Btw: rubber is almost as poor of a conductor as air is.

 

Your post is hilarious. Most home garden hoses are 25' or 50'. If such a hose was used with water heated to 120F there is no doubt that the water would still be very hot when it comes out. It is laughable to suggest that it would be close to freezing, even at -14F.

 

Its not like we don't know that Tacos rust...or I guess there are a couple people out there. Treat it before it starts, if not you just got hosed -a con for these trucks.
