Magnetizer?

[Streetwise]

I just picked up a 2002 Silverado/1500/4x4. After further inspection, I noticed it had "Magetizer" magnets on the coolant, air and fuel lines. I did a little research and it's supposed to be a fuel saver etc. Anyone have any experience with these things?
Also, the truck runs great and is a solid truck. The only thing it needs is tires. Any recommendations?

somebody got suckered into spending money they didn't need to! Not you, the previous owner!!

If you cross your fingers and shut your eyes real tight...wish harder than you've ever wished in your life........They still dont work...LOL!! Previous owner must have lost a bet.

I recommend you remove them, you'll save a few ounces of weight and they make great refrigerator magnets!

check if you do not have magnet underneath the gas pedal. so it does not draw it too much down towards the floor.

now, I'll aplogize for myself being goofy, and for the rest of the posters. It is a very serious question. No, they will do squat on power/mileage thingy.

Lmao! You guys are funny here! Good stuff. The funny thing is, it also had those electrical rust preventers. Wires everywhere. Ripped it out 10 seconds after I opened the hood. I guess the previous owner had some superstitions.lol.

well now, there is a legit device, used by car manufacturers, that is electrical in function and is connected to the body. rust, or oxydization, requires specific polarity for O2 to interact with Fe ions. that device is changing that polarity to the point that electrochemical reaction, called rusting, just does not go.
it's been around since early 90s, i believe, and was used, if memory does not fail me, on Hondas at least. so, it might have been legit doohickey.

now, if you want to see REALLY weird stuff, look into joe cell. that is some serious magic, mah man

I posted a thread a long time ago, that is gone now. But Popular Mechanics did a feature on all of those fuel saving gizmos. From the magnetizers, the "tornado", water injection, ionizers. None of them had any positive effect on fuel mileage, one of them, if I recall right the "tornado" actually caused a drop in MPG

on your tires ...I have used C rated tires on my 1500...these give a good ride...the E rated tires for 2500 are too stiff..

firestone steeltex 245 75 r16 LTX tires C load rating came with special order when new 90,ooomi...replaced with same 3years ago now 120,ooomi plenty of tread left, and a smooth ride also not expensive tire..

rotate every 10,ooomi....

Much like my T-Blazer, it rides very well. I was suprised. The tires I have now seem to have decent tread left, but they're noisy, cause vibration, (they are balanced) and when you run your hand over the tire tread, you can feel spots where it's raised up. I don't know if it was from not rotating them, or what. I will look into the tires you mentioned, thanks for your advice. Do you know if you can put a bigger tire on?

Sounds like the previous owner would have been a good customer of those snake oil salesmen of that roamed the frontier in the 1800's

I have seen a few ICCP (impressed current cathodic protection) systems marketed to protect older, less well preserved vehicles from rust. I don't know anything about their true usefulness, but working in the field they may be of some advantage to them if you're in water alot...boat launching or mudbogging, or exceptionally high-salt use regions. A couple of zincs bolted to the inner frame rails would work too.

the only place I seen this is on boats...keeps the prop from disintergrating...also if it has prop shafts keeps them from corrosion in salt water..they also will reduce the engine coolant [sea water] portion from corrosion...esp. if its a closed system...with heat exchanger...

I don't buy into electrical current preventing rust. I've worked on many cars that had the systems on them, yet they were still a pile of rust you needed a tetanus shot to touch. How much current would you need for there to be any significant prevention? Probably more than the vehicles 12 volt system would allow. Gimmick at best.

when two metals like as an example copper and steel touch each other in a salt solution electrons flow..this then causes the metals to disintergrate....

my aluminum swimming pool after 10 years all the metal support pads where the pool ground wires where connected melted the aluminum TO dust...the other pads where good....

unless you drive your vehicle in the ocean or in a very salty environment this would not be that effective...sealing the metal sufaces has worked for me..mineral based undercoatings ...

this is why also the coolant system must use distilled water and be serviced whenever the coolant starts to get discolored as this is the metals getting into the coolant ...
