5 Signs You Shouldn't Buy A Used Car

[@EngineeringExplained]

Good number of folks asking about the bluetooth scanner I'm using. Here's a link! amzn.to/2AwvtSQ I've had this one for maybe 4 years or so (EricTheCarGuy actually gave it to me). It's worked great!

[@julestiernan7056]

I love your channel, been a fan for some time, your knowledge and no nonsense approach to engineering and mechanics is unparalleled, for this I thank you sincerely. I have a question about the scanner you are using, can it also give you vehicle information about the car as you drive? I am looking for something that will give me engine temp and oil pressure in real time that I can have in my field of vision on my phone as I am driving, more just to monitor certain parameters in different driving environments. Any feedback would be greatly appreciated, continued success my good man, I always look forward to your uploads. Best channel and best host on the subject!!!!

[@EngineeringExplained]

Yes, it actually has a live display where you can read things like temperature, throttle position, that kind of thing. It will depend on your make and model what it can read, but you can get live stuff and record data. It's quite neat! I'd recommend looking into compatibility with your make and model, but it's worked well with the cars I've tried it on.

That also depends on the dealership/technician. I've worked for a hyundai dealership that would sell used cars with what I consider major issues without repairing them. They'd ask that I clean it up and make it as good as I can without any parts. I.e. I had a hyundai tuscon with oil on the front cover and they wanted me to clean it up and do what I can to slow/stop the leak but just pulling the cover and replacing the gasket and doing an inspection behind the timing cover was a no-no. I no longer work for that dealership btw.

I have a special tool. It's a spring loaded magnet, you stick it to a panel and slowly lift of, when the magnet lets go it has a scale that tells you the thickness of the paint. Obviously if it doesn't stick at all, it's been bogged up. Sometimes the best time to check for smoke is at night with some one driving behind you. Their headlights will highlight the smoke. Also if it smokes going up a hill, then it's the rings, and when you engine brake down a hill and then you blip the throttle if it smokes it's the valve stem seals.

Since it has the same engine as a yukon denali, which isnt that problematic and is fairly cheap to fix. In addition to being literally being as floaty and comfortable as a yacht.

after 2 of my family members went against my advice and purchased the used vehicle they wanted anyway. i came up with one sign you shouldnt buy a used car. 1. get on craigslist and find the highest mileage of the same model you are considering. if you are excited because this car only has 80k miles but you can only find 4 of them for sale, the highest with 110k miles. high and low miles is relative to the car you are considering. i would actually say that for THIS car, 80k is really high miles.

When scanning for codes , if you find none , check to see if all the " Monitors " are ready and able to send a code .

I see you are using the BlueDriver! It’s an awesome tool. I was having an intermittent cooling fan issue on a Mustang GT this summer past and that tool was instrumental in allowing me to monitor the temperature as I drove to avoid ruining the engine. I changed the thermostat, radiator cap, had the radiator out and tested (good) and even replaced the cooling fan assembly with a new one from Ford. But the issue persisted. I was told it could be a head gasket but I had no symptoms for that. I was getting no codes for anything either. A ford tech looked at it with a Ford computer and was baffled. I was fixing to replace the PCM when I decided to disassemble the BEC (bussed electrical center) in the engine bay. Lo and behold there was my issue, a short in the connector to the high speed fan relay. I got a salvage BEC and a new connector and repinned the wires from the old connector into it and problem solved! Right before I had disassembled the BEC the BlueDriver had started giving me an open fan circuit code. Worst issue I ever had to troubleshoot on a car but now it’s working great, well was, it’s winter stored now. Even the stereo sounds way louder and clearer and I was having an intermittent transmission flare issue that has gone away too. I had an issue in that BEC for a while that was interfering with voltages needed for other things like the transmission operation. It progressively got worst with the cooling fan issue. I put a lot of time into troubleshooting it, working on it myself, reading stuff online, etc. So glad I solved it and that the car did not catch fire!!

[@pattyeverett2826]

One thing you can use to check for rust is take a small magnet with you. If bondo has been used to hide rust, the magnet will not stick to it. In my younger days, I knew a fellow who moved from Michigan to Texas(where I live), bringing his 1969 Buick. This car had rust where you would not think a car could rust. After he got a new car, he bondoed the Buick up, had a cheap paint job put on it and sold it. Another person I know caught a body shop in a lie with a magnet. He had a truck he needed some paint work on and the body shop claimed the hood was aluminum and would cost more to paint. He stuck a small magnet to it. Magnets do not stick to aluminum.

This is why I always change my oil every 3000 miles, and filter every six. Coolant changed every five. Have yet to reach the 10,000 for my transmission fluid in my newer car. Just keeping up on those things is a good way to make sure your car goes over 300,000 miles.

[@ANelsonViolin]

One thing to know about OBDII codes: not only do you want to check if there are any codes stored or codes being displayed, but you want to see if there are any pending codes and Not Ready statuses. If someone is trying to sell a car that has been throwing up codes and showing a check engine light, they may try to fudge it by clearing the codes themselves to make it appear to the buyer that there are no problems. There’s an easy way to tell if this is the case: plug in your scanner and check the I/M readiness section. If anything reads NOT READY or PENDING, it can absolutely mean that the owner is trying to hide something!

[@Ravaniscool]

I bought a 1997 Pontiac Trans Am with 7,800 original miles. I took it on 2 test drives without any problems. The next day after purchasing it I put new tires and changed all the fluids.

Old car guy here. Old cars/trucks for old guy. Lots of very cool rides that all needed brakes, wheel bearings, transfer case, fuel pump/lines, fuel injectors, TPS, EGR, PCV, Coil driver, plugs & wires, synthetic oil when it even looks dirty and plenty of rust. They all made plenty of 100,000 mile odometer rollovers. I love bass, no treble, but it's all about the oil, no trouble. p.s. Love that 420 code. My repair procedure is personal, however. (O2 spacer and full bowl). My '79 Z28 has 420 mechanical logic...windows automatically roll down some, depending on severity.

[@jerryfacts9749]

These are excellent tips. Many of the newer cars no longer have dip sticks for checking the oil in the engine and or transmission. It would be a good idea to have a proper quality scan tool and go through the readings to view for any error codes. If the person is not proficient to properly check out a vehicle it is best for them to pay a qualified mechanic to check out the vehicle. If you can have access to a lift it is a good idea to check for loose ball joints, loose suspension parts, condition of the tie rods, struts, springs and shocks.

[@DAN007thefoxx1]

If buying a classic car it might be normal for it to bellow out a big white cloud of smoke when its very cold outside and the engine is still cold. Also a few small leaks are common. But you still dont want to see gushing fluid or smoking very heavily even after its warmed up.

It has the clutch and throttle on opposite sides of a normal car (clutch on right, throttle on left). My dad, no joke could be heard 1/4 mile away flooring it and grinding gears (for a solid 4 minutes before I could run over to him), because somehow he couldn't figure out why it wouldn't go into gear... Now, you would think, well maybe if this engine is revved to max shooting flames out the side, well maybe, just maybe, that's not the clutch? That transmission died shortly after. Sad part is he knew it was backwards, but really the worst part is not stopping and thinking, hmmmm.... maybe something is wrong....

We wish! The P0420 family (0420, 0421, 0430, 0431) are troublemakers. 0420/0430 are often exhaust leaks ahead of the converters (or even really dirty injectors) but could also be a bad converter. 0421/0431 seem to always be bad pre-converters. Trying to fix a P0420 or P0430 by blindly replacing the converter can take the car up a very dark alley. The code goes away because the new converter is just enough better to clear the code, but it comes back six months later when the new wears off and the problem gets worse. A second replacement lasts a month or two as the problem gets even worse. I fixed the last P0420 in the family - my daughter's 2002 Sienna - by instructing her to use top tier gas. I cleared the code a week later and it didn't come back for nearly a year. She had gone back to random gas.

At 5:10 if you run the AC on a hot humid day during the test drive, expect to see condensation dripping from somewhere in the back of the engine bay near where the condenser is. You can differentiate condensation from other fluids because it will be clear water. Any other fluid leaks will have a different color (coolant will be either green or orange/red, break fluid will be amber, oil will be brown or black, etc) or a different viscosity thicker than water.

If you don't live in the rust belt maybe you can be that picky about rust on suspension bits, but if you live in the snowbelt states, you're going to have to accept some rust on suspension components. In a dream world, DOT's the world over would quit using salt, just use sand and everyone would buy snow tires, but since that is bound to never happen, we must make a compromise, haha.

[@EngineeringExplained]

Yeah, it’s a shame we still use corrosive ingredients for snow. Snow tires and sand/dirt works great!

[@russlehman2070]

Colorado uses lots of mag chloride. It melts the snow and ice beautifully, but it's every bit as corrosive as salt, and it puts a layer of crud on everything it touches: windshield, paint and headlights included. Under no circumstances run out of windshield washer fluid when the roads have been treated with that stuff. You will be driving blind in 5 minutes or less. In fact, I've always suspected that it was actually the people who make windshield washer fluid who first came up with the idea of using mag chloride for de-icing. It must have tripled their sales.

[@AmandaHugenkiss2915]

I used to put my vehicles in the garage, crank up the heater, and flush underneath with hot water every time they ran through salt. It slows rusting, but nothing will stop it since they would have sat all day at work or school marinating. I did keep them rust free for a long time though. Long enough that comparable cars were rusted away or in the junkyard.

I also like to check for bubbles in the oil, particularly if the seller changed the oil.
