Shopping for a car or truck? What to look for in a secondhand vehicle?
Make This Your First Inspection
The Most Gainful Test and time saver is to inspect the inside of the exhaust pipe at the end of the vehicle. Check the color, it should be clean, sometimes a neutral light grey and void of any oil. The cleaner the better! Black and sooty reveals a poor burn, resulting in poor gas mileage and poor performance. This may the only test you need to make before walking away from the sale. Black dirty looking exhaust pipes usually indicatesl worn piston rings, damaged valves or worn valve stems, a costly repair item! If the exhaust test checks out, then follow up with these other tests. Check the Exhaust pipes and muffler- visually inspect for rust and holes.
Tires
tire wear can tell you a lot, are they wearing evenly across the tire? Rough driving and rough roads can cause front end damage which may or may not be able to be corrected with an alignment.
Go Further
If the exhaust pipe is black inside, more tests are in order. Remove the spark plugs one by one and note the condition of each one. The color tells us a lot about the health of each cylinder. Follow up with a compression test of each cylinder, the readings should be consistent with each other.
The Other Things To Look For
Shocks- you can do a basic test. First do a visual inspection, there should not be any oil on the outside of the shock. Try rocking the car back and forth above each tire, one at a time. The car should quickly stop bouncing. If the car continues to bounce after you let up, they may need replacing.
Steering Wheel Play- try turning the steering wheel left, then right while watching the front wheel on the drivers side. If there is excessive motion in the steering wheel, before the wheels move, it could be an indication of worn tire rod ends. Worn tie rod ends cause vehicles to wander on the road.
Under the hood- visually inspect everything, looking for leaking fluid. Check the radiator for rock damage and check the radiator hoses, look for cracks. Try squeezing them in your fingers, they should feel rubbery, not hard. Check the fan belts for cracks and damage.
What A Good Eye Can Tell You
Have a really good look at the wear of the steering wheel and the rubber on the brake, clutch pedals. If the speedometer says 80,000 kilometers and the wear indicates otherwise, the odometer may have been turned back. Also uneven spaced numbers of the odometer, indicate they have been turned back.
Last but not least if possible take the vehicle for a road test, listen for scraps, knocks etc., and no sound is best! Try the brakes, hand brake, turning signal, windshield wipers, lights and horn. Take the vehicle down a long hill, let it coast then at the bottom of the hill step on the gas, a blue cloud behind you indicates worn rings, cyclinders and valve guides.
By locating any of these problems you will be able to bring it to the attention of the seller. You might be able to get them to lower the price in order to have the necessary repairs done. On the other hand you may avoid a major headache.
