Liquid de icer and frame rust

Specifically tacoma 2014, 2015 are the frames immune to rust from magnesium chloride?
Reason i ask i called 2 different toyota dealers in spokane about doing a frame inspection before i drive down and look at the vehicle. Long drive for me. They both said the same thing. They dont even do frame inspections cause they dont have the problem unless the vehicle came from Canada or a salt state. Is this a true statement? The vehicle i am interested in has been in the spokane area its whole life as far as maint records go

 

No. The frame can and will rust.
Even if the truck lives in a state that doesn't use chemicals on the roads, the frame can/will rust.

The frame itself holds water. Crawl under one and look at the muti-layered frame.
Water gets between the layer and eventually you'll see rust.

 

@Blanked check out this post on mine. https://www.tacomaworld.com/threads/another-frame-corrosion-question.782069/ post 19 from Msgt O haves the link to the message from toyota. Print it out and read it fully and then take it with you and go have a conversation with them about it. Its in black and white they can't deny that. Slowly make your way up the food chain until it gets done. Just be nice and stay calm about it. I was told the same thing until I brought this paperwork into my dealer on it. Hope this helps

 

Yes, as @TnShooter stated, the 2014 and 2015 model years will still rust.

 

Thanks! I didnt know Corpus had frame issues? I am from La Porte. Before i moved to idaho

 

As long as i get fully underneath the complete frame cant i do an inspect myself? Or its much more detailed than that for someone with no experience? Would a paint and body shop be better since both toyota dealers claim they dont have frame rust problems in the area

 

Well if you drive it down the beach all the time like the previous owner (I assume) did then yes. But it really doesn't matter if it gets wet and water collects where it shouldn't be its going to rust no matter were you live. The salt just helps expedite that a little. I do know its not as common down here. I think the service manager said it was only the 2nd or 3rd one that he has seen.

Don't waste your time with corporate because they will just argue start at the bottom and work your way up. Once the service manager actually read the message he was like ok inspect it and if it qualifies why would I be against it as it provides a week worth of work.

 

The Maine study, based on a year-long study of winter road maintenance in that state, found that while all chlorides cause corrosion, both calcium chloride and magnesium chloride are particularly corrosive because of their ability to retain moisture.

 

If you look at the message it will tell you were to inspect and what to look for. On mine I put a hole in the frame by putting it on a jack stand and on the other side there was a hole on the frame face. I believe I loaded pictures #post 9 (there is only a picture of the hole that I put in it from the jack stand) of it in the thread I sent you to earlier.

 

No vehicle is immune to rust especially when salt and/or chemicals are involved, some are more resilient than others but they all will rot away in the presence of chemicals and/or salt if no preventative measures are taken.

Always get a pre-purchase inspection (not not just the frame but the whole vehicle) by a shop (not the selling party) or yourself if you know what to look for before buying any used vehicle, too many people buy a used vehicle and find out later they bought a doctored up POS.

 

If you're capable do a pre inspection with a hammer. The mag chloride stuff is highly corrosive,I used to put it down on roads so I'm speaking from experience. The dealer doesn't sound like they know what they are talking about,typical.

 

Go crawl under it, take a few pictures and post them up here.

 

The problem with Tacoma frames is that many of them have been undercoated. That might not have been terribly bad when the truck was new, but I'm seeing many of them around here (the rust belt) where the undercoating is recently applied by unscrupulous used car lots to hide the rust. And that would be a very bad thing.

As for who should inspect your frame, it has to be a Toyota dealer to ensure that you're covered under the 12 year replacement plan.

 

I am a bit confused on the 12 year plan. It says date of first use. If i take a 9 year old truck for inspection it doesnt reset the clock when the 12 years starts again does it?

 

This, MC is even worse the CC and the liquid brine garbage used on bridges may as well be steel acid. All of it will eat the living H E double L out of frames, axles, suspensions and any exposed/bare steel or castings.

The ONLY acceptable undercoatings on a Taco frame [or any vehicle frame for that matter] is a non hardening non rubberized fluid film type oil/wool lanolin based treatment. I've used FF and LPS 3 and both do an excellent job.

If you see even Toyota's rubberized coating they used for awhile, run away, it'll be FAR worse underneath then you can imagine.

 

No date of first use is the original purchase date from the dealer. You may have a 2014 but if it was built late and not sold until 2015 the date of first use would be 2015 and 12 yrs from that point it's covered under the program.

 

@Blanked to answer your other question that I don't see on here but it's in my email. If the previous owner had done that I would have rusty rear bumper, tail pipe and things like that. But I don't everything else is solid.

 

Tacoma is known for rust. Toyota is known for rust. No it is not immune. The frame design nor the coating.

Audi hot dip galvanizes their chassis from factory. That is why they have a 12yr anti perforation warranty. Toyota does not.

welding galvanized is also hazardous. Non galvanized is not. Pretty sure it creates phosgene gas fumes.

WA supposedly used non corrosive sand. CO uses mag CL which is corrosive.

Either 1. They truly do not have rust problems and the truck is from there
Or 2. They’re hiding it and too lazy to hold their iPhone underneath the truck or take a picture when it’s on the rack in the shop.

used car trade ins at the dealership go into the used car department to be raised on the lift, inspected by a technician, and any potential repairs quoted to see if anything is needed to make it legal to sell. Whether that be smog or tire depth or anything else based on local laws.

there is budget within lowball trade offers and expected flip profit for certain repairs to be done. Depending on vehicle it may have already been raised on the lift where inspecting and documenting frame condition would not be hard to include in the portfolio of pictures they have taken of the cupholder from 40 different angles using a $1000 Nikon done by a porter.

I’d be curious to see CO use sand. In my experience living there when the road was snow and ice a plow was not there.
When the road was dry a plow was there dragging and scraping the plow on the ground sparking.
Snow and ice never kept me from work despite tires I ran all year regardless of conditions or plows.
The rich folks swapping to studded winter tires probably did even better.

I have a steel bumper. Came powder coated. Started rusting within a year of being in CO despite a schedule of underbody car washes and putting garden sprinkler underneath.

not every dealer is honest. Dealt with one sales place. They seemed honest. Looked at a truck at a different sales place. They did not reveal the truck had collision damage.

sales job is to say words to make you buy something. Tech is not. If you want to know reality ask any tech in that state what they think and what they actually see working on cars there on a real life daily basis being underneath them.

 

They are lying to your face

 

Wa mainly uses mag and cal on their roadways. Heavily. Sand is used when temps are too cold for deicer to be effective. People bitch when sand is layed because it gets thrown up and eats their paint, cracks their windshields, etc. I wouldn’t call it sand, it’s more of a mixture of sand, small gravel and medium sized rocks. Sand is utilized more in less populated areas for instance PO county in NE wa and Lincoln county ea cen wa.

Galv steel still rusts rapidly when exposed to de icer. Galv steel rusts in a relatively short period when exposed to just water. I work at a steel mill that specializes in galv coated structural and non structural construction.

Our millrights and fabricators are required by wa state law to wear papr’s when welding on galv products. Shit is nasty stuff, You don’t want to be breathing.
