^^^This^^^Good idea, and excellent advice.
It's your car .... it's your responsibility.
Trust but verify.
I've changed my oil every 4 to 5k, it makes no sense to dump out oil that still looks new. If it goes bad sitting...
The truck hasn't seen any hard work in its life, a few loads of stuff moving but household stuff and a few tractors and tool boxes isn't any serious work for any truck.
The oil in it still looks new at 3,351 miles. I would also think that with the synthetic oil the oil changes can go a bit further.
If I go by time not miles, then last year the truck got zero miles, it sat from 3-22 to 1-25 because I was at my other house and have been using the older truck more lately. The only reason I drove it three weeks ago was to go get new tires for it. The spare set were getting pretty dry rotted looking so I replaced those and bought a new set for the truck as well since those are original as well. I really hate to take off the OEM tires since I can't buy them new anymore,
...and refilled the truck with the original coolant.
Never has the coolant shown as being weak or discolored in anyway.
The trucks at work ranged from 5 to 20 years old. The coolant never got drained and replaced, it got 'replenished' or recycled through a machine that would filter and reuse it. Those trucks, mostly International and Freightliners, ran for over a million miles.
No it is not. That’s silly.So the consensus is that Walmart's Super Tech AF is a fraud?
I find it hard to believe that they sell millions of gallons of coolant and oil and its all subpar snake oil.
If they were selling automotive fluids that were dangerous to use they'd have been sued out of business years ago.
I can believe that some creative advertisement is at play on some items but work used that red coolant for years with no issues but a few bad gallons mixed into a huge system has far less effect then in a pickup truck.
If the positive terminals on the battery are disconnected then how would there be voltage in the coolant?
I tested my 03 and the 96 again and I get no reading between the ground terminal and the positive lead in the coolant. If water or coolant is a conductor, then its really no different than reading voltage at two ends of the same cable or across a metal surface.
Going on the fact that the ohms test in water or the coolant shows a 1v drop than it means the ground to fluid voltage test is going to show near perfect continuity thus no voltage?
Where is the voltage supposed to be coming from?
If you're getting zero volts, then it is good.Electricity takes the path of least resistance.
This truck has at least four ground cables on it. There's one from the battery to the alternator, one from the battery to the frame and engine block on each side from each battery and one from the head to the firewall that looks like a braided strap. (Plus another strap jumping the left front cab mount to the frame.
For a test, if this works then taking a battery, a tin cup or pan full of old antifreeze, and a meter set to volts, I should see some voltage between the neg terminal of the battery which is connected to the soup can, and the positive lead when it touches the coolant?
I get zero, the meter continues to hunt just as it did without being connected.
I don't see how its going to see voltage if there's no positive power supply to the coolant elsewhere. It can't generate current and the vehicle, with everything the coolant touches being grounded to the battery would need to see current somehow for it to conduct current. I'm also doing the same test with five meters here, three of them top grade equipment.
I have never had a cooling system that got rusty, ever. I ran my one LTD which was my daily beater with a 302 in it for 19 years. I bought it with 33k on it with a blown motor from the fire department. I stripped off the decals, pulled out the motor and found #2 cylinder wiped out. It had no warranty but I new that when I paid $900 for a three year old car at auction. I called around to the junk yards and found a wrecked '94 Mustang with 2,200 miles that had been wrapped around a tree. The motor and trans were both good. I put the 5 speed on the shelf and used the motor in the LTD.
To make it short, I made it work and it worked well. I ran that car for 19 years 265k before selling it not wanting to deal with having to repaint it. It ate the first transmission at 110k, I rebuilt it and never did anything to that car but oil and filter changes brakes and tires. It got partial coolant changes over the years with minor repairs, one being a new heater core at 65k, and another at 180k, but it was never drained and it got sold with all the original hoses, radiator, etc. The buyer drove it for 10 more years using it to tow his boat till he got old and died. I doubt he even checked under the hood if a light didn't come on, if ever.
I'm not saying I don't do maintanence but I can tell good af and oil from bad.
My Lincoln lets me know when it needs an oil change, I can here the difference in how the motor sounds and around the same time the oil starts to look dirty. Usually around 5,500 miles or so. I run only Mobil 1 5W30 in that car. Its also never had a coolant change or flush but the radiator had been out of it once after the trans cooler started to leak. It was topped off with about a gallon of fresh coolant on top of the clean original gold coolant it came with.
What’s kind of funny, in college, we have theory, and application.I do think my Cummins 2005 has the red coolant, it has not been a problem. I have older vehicles. I may be confusing red with Dexcool which can turn into jelly, so I have just avoided ever buying any as I don't want extra troubles and have not need any for the truck yet.
When combined, orange and green coolants create a jelly-like substance that can stop coolant flow and lead to overheating, amongst other issues.
- Orange Coolant, or Dex-Cool, is made with organic acid technology (OAT). Dex-Cool (on Amazon) was introduced in 1996 by General Motors. It’s designed for newer cars that have higher amounts of nylon and aluminum components. These mixtures utilize organic acids to help prevent corrosion.
Although some coolant brands claim that it’s safe to mix their product with Dex-Cool, it’s recommended to air on the side of caution. Mixing coolants can cause severe damage to the engine and the vehicle, leading to hefty repair costs.
