How to Inspect a Diesel Engine Before Buying a Used Semi Truck: American Motors 

He picked one of the cleanest cummins motors possible.

You did a very great pre trip inspection sir.

Noting we can do will substitute PRE- PURCHASE INSPECTION. It helps to do this important checks and obviously to filter the good from the bad. However, at the end we must do pre purchase inspection with a professional shop.

Did anyone notice the fresh new paint on the frame rails, radiator support brackets, new decals, steering rod, new wiring looms with new protector sleeves? But original faded plastic air breather tubes?

You forgot to mention the valve cover always open that up!!! and inspect the cams and rollers

I'm not mistaken I saw quite a bit of smoke coming out of that blow by test

Avoid anything with new tires and fresh paint... read between the lines, your alignment is out and frame is bent, and rust is going to take over. Also, check blowby and feel how tight it is, agree on a price and put $200 non-refundable down and send oil sample to CAT lab ($15) and wait... you don't buy a house without an inspection so don't be an idiot again. That is the best $200 you will ever hand someone. Also check if there are maintenance records... that can sometimes be instructive, avoid all DEF Internationals and DEF engines in general if you can. Codes can be erased temporarily or pieces disconnected... do not trust. Get YOUR KNOWLEDGABLE and trustworthy mechanic to look it over. Also, 100% of the time, if one area was not maintained (eg it has a new engine), then nothing else was either. run away, those are bankruptcy traps. Good luck.

I been at Volvo dealer every 2 weeks for 24 hours. Only 200,000 miles. Different issues. Fuel pressure control switch, box number 1 bad( ck engine light came on) ,APU problem once a month. You earn the 8mp gallon. Like Volvo trucks but they go to the dealership often. Down time even though warranty covers.

I really like this inspection thanks.

Damn! I realize I do that every workday on that same engine

This is my fevret truck sir

Thank you, very helpfull

Impressive knowledge.

Thank you bro so much.

great video my man

If the dealer cleans and paints an engine u can't detect shit 400 mile test drive under load and dino testing u want a truck they haven't changed the oil yet trans rears engine so u can get it analysed

You can do all those inspections and still wind up with a lemon, It's a real crap shoot when buying a truck. You just have to be lucky to get a good one. You can prevented from buying a potential bad truck. but sooner or later.. you MONEY GODS will get your money.

Good Job. salute to you.

What are the most common problems with Used Freightliner? When buying a used Freightliner what are the vital things to check or look for?

Great video.Excellent!

Depends on how many miles are on the truck.Buy and take to the mechanic and tell him you want a engine rebuild.That way you can get a new engine to last a quite a bit longer, and hopefully everything is good

Bro you might think about having a mechanic do this. Your Insp is all over the place..

Great job

Check under the truck for signs of leaks as a final after test drive.

I like to see how the truck looks in my driveway

Stick a match in that rad. 😀

First u should do is check if it has a def tank 😭

Thank u sir so much

If the truck has a smog motor or def tank/reservoir walk then run away.

Why was there water drops inside the oil tube were u put oil at end of video when you took off oil cap off can you tell me if thats normal

Take the engine apart to see if all the parts are there. 😀

You have to check check the check and check again

You need to get some tools out, you just did a pre trip inspection .

Or you could go buy a new truck with a warranty....just sayin

Check check checking check check checking check 🤔

Currently studying for my CDL, I’m still in the studying phase but can any seasoned drivers confirmed what he mentioned? As well as hit on anything he may have missed for me?

better of buying a truck for 20k and just do a rebuilt all over.

Uhh , thanks.

Check.check.check

Sell me a truck that you have inspected please, so my investment is secured!
